Differences in how a PHP array is built - php

I'm trying to get an array to output in a key and value format. When I use the second style shown below it works fine, but when I use the first style I don't get the same results. I think something is different in how the keys are used but I'm not entirely sure.
So, is there any difference between building an array like this:
$featured = get_post_meta($profileID, 'profile_featured', true);
if ($featured == '1'){$my_fake_pages["featured"] = "Featured";};
$celebs = get_post_meta($profileID, 'profile_celebs', true);
if ($celebs== '1'){$my_fake_pages["coversandcelebrities"] = "Covers & Celebrities";};
$fashion = get_post_meta($profileID, 'profile_fashion', true);
if ($fashion == '1'){$my_fake_pages["fashion"] = "Fashion";};
$beauty = get_post_meta($profileID, 'profile_beauty', true);
if ($beauty == '1'){$my_fake_pages["beauty"] = "Beauty";};
$advertising = get_post_meta($profileID, 'profile_advertising', true);
if ($advertising == '1'){$my_fake_pages["advertising"] = "Advertising";};
$bio = get_post_meta($profileID, 'profile_bio', true);
if ($bio == '1'){$my_fake_pages["bio"] = "Bio";};
and writing one like this:
$my_fake_pages = array(
'featured' => 'Featured',
'coversandcelebrities' => 'Covers & Celebrities',
'fashion' => 'Fashion',
'beauty' => 'Beauty',
'advertising' => 'Advertising',
'bio' => 'Bio'
);
Thanks in advance.
** To be clear, I know one is conditional and the other isn't. What I'm wanting to know is if the output style of the first example is equivalent to that of the second, where the key is the index of the array rather than a number being the index, and the value is still the value.

They are the same. To prove it, I've simplified your code and compared the two generated arrays
<?php
$a["featured"] = "Featured";
$a["coversandcelebrities"] = "Covers & Celebrities";
$a["fashion"] = "Fashion";
$a["beauty"] = "Beauty";
$a["advertising"] = "Advertising";
$a["bio"] = "Bio";
$b = array(
'featured' => 'Featured',
'coversandcelebrities' => 'Covers & Celebrities',
'fashion' => 'Fashion',
'beauty' => 'Beauty',
'advertising' => 'Advertising',
'bio' => 'Bio'
);
$same = !array_diff($a, $b) && !array_diff($b, $a);
var_dump($a);
var_dump($b);
echo "<br>Same = $same";
This outputs:
array(6) { ["featured"]=> string(8) "Featured" ["coversandcelebrities"]=> string(24) "Covers & Celebrities" ["fashion"]=> string(7) "Fashion" ["beauty"]=> string(6) "Beauty" ["advertising"]=> string(11) "Advertising" ["bio"]=> string(3) "Bio" }
array(6) { ["featured"]=> string(8) "Featured" ["coversandcelebrities"]=> string(24) "Covers & Celebrities" ["fashion"]=> string(7) "Fashion" ["beauty"]=> string(6) "Beauty" ["advertising"]=> string(11) "Advertising" ["bio"]=> string(3) "Bio" }
Same = 1

The if() version only adds to the array if the conditions are met. the second one adds everything, unconditionally. that has nothing to do with the keys.
It's the difference between going to the grocery store with a shopping list and only getting what's on the list, and going to the store and buying 1 of everything.

If i understand your question right, you want to know if building an array like this:
$my_fake_pages["featured"] = "Featured";
$my_fake_pages["coversandcelebrities"] = "Covers & Celebrities";
$my_fake_pages["fashion"] = "Fashion";
$my_fake_pages["beauty"] = "Beauty";
$my_fake_pages["advertising"] = "Advertising";
$my_fake_pages["bio"] = "Bio";
is any different than building it like this:
$my_fake_pages = array(
'featured' => 'Featured',
'coversandcelebrities' => 'Covers & Celebrities',
'fashion' => 'Fashion',
'beauty' => 'Beauty',
'advertising' => 'Advertising',
'bio' => 'Bio'
);
The answer is no. Both generate an associative array (instead of a numbered array) like this:
array(6) {
["featured"]=>
string(8) "Featured"
["coversandcelebrities"]=>
string(24) "Covers & Celebrities"
["fashion"]=>
string(7) "Fashion"
["beauty"]=>
string(6) "Beauty"
["advertising"]=>
string(11) "Advertising"
["bio"]=>
string(3) "Bio"
}
And also since PHP 5.4.x you can have a "short syntax" array generation like this (notice the []):
$my_fake_pages = [
'featured' => 'Featured',
'coversandcelebrities' => 'Covers & Celebrities',
'fashion' => 'Fashion',
'beauty' => 'Beauty',
'advertising' => 'Advertising',
'bio' => 'Bio'
];

** To be clear, I know one is conditional and the other isn't. What I'm wanting to know is if the output style of the first example is equivalent to that of the second, where the key is the index of the array rather than a number being the index, and the value is still the value.
Yes, if all conditions evaluate as true, then the array format is exactly the same. Both will be associative arrays with the same key

Diference between $var = array($key => array()) VS $var[] = array($key => array())

i have a question about these 2 ways of declaring the array (I thought they would be the same):
$result[$zone->id]['activities'][$activity->id] = array(
'title' => $activity->title,
'image' => $activity->image
);
$result[$zone->id]['activities'] = array(
$activity->id => array(
'title' => $activity->title,
'image' => $activity->image
)
);
So my goal is to provide an array that is sorted by the Zone then by it's activities listed under the array of "activities".
The first array gives me the following result which is correct for my example:
array(3) {
[5]=>
array(2) {
["title"]=>
string(15) "Oftalmologistas"
["image"]=>
string(28) "logotipo_1575907014_4232.png"
}
[6]=>
array(2) {
["title"]=>
string(7) "Óticas"
["image"]=>
string(28) "logotipo_1575907021_1130.png"
}
[7]=>
array(2) {
["title"]=>
string(21) "Outras especialidades"
["image"]=>
string(28) "logotipo_1575907034_8988.png"
}
}
But the second array gives me the last activity found and replaces the two above it doesn't add them to array instead it replaces them.
array(1) {
[7]=>
array(2) {
["title"]=>
string(21) "Outras especialidades"
["image"]=>
string(28) "logotipo_1575907034_8988.png"
}
}
My goal here is to understand the diference syntax between them why the first adds them to array while the seconds replaces. Also any other way of declaring the array to the same first value. Thanks in advance!
this is just simple nested arrays with different keys and values for better understanding i change it to this code:
$result[100]['activities'][200] = array(
'title' => 4000,
'image' => 3000
);
$result[300]['product'] = array(
444444=> array(
'title' => 5000,
'image' => 6000
)
);
echo '<pre>';
var_dump($result);
first we have two array and inside each of them again there is another two arrays with different key and values if you look at this picture i uploaded i think you can understand completely.
nested array result
for first example
$result[$zone->id]['activities'][$activity->id] = array(
'title' => $activity->title,
'image' => $activity->image
);
You are assigning value to key "$activity->id"
Here as id gone be dynamic it will create new key everytime.
In second example
$result[$zone->id]['activities'] = array(
$activity->id => array(
'title' => $activity->title,
'image' => $activity->image
)
);
You are assiging value/array to activities.
So every time you try to assign value to activities key it will
replace it.

Make multidimensional array with php and pdo

i want to edit a script i found online. is has an hardcoded array like this.
$servers = array(
'Google Web Search' => array(
'ip' => '',
'port' => 80,
'info' => 'Hosted by The Cloud',
'purpose' => 'Web Search'
),
'Example Down Host' => array(
'ip' => 'example.com',
'port' => 8091,
'info' => 'ShittyWebHost3',
'purpose' => 'No purpose'
)
);
Result:
array(2) {
["Google Web Search"]=>
array(4) {
["ip"]=>
string(0) ""
["port"]=>
int(80)
["info"]=>
string(19) "Hosted by The Cloud"
["purpose"]=>
string(10) "Web Search"
}
["Example Down Host"]=>
array(4) {
["ip"]=>
string(11) "example.com"
["port"]=>
int(8091)
["info"]=>
string(14) "ShittyWebHost3"
["purpose"]=>
string(10) "No purpose"
}
}
I put this data in a database and want to make the same array but i dont seem to get it working
This is the code i added to make an array:
$query ="SELECT name, ip, port, hosting FROM sites";
$select = $conn->prepare($query);
$select->execute(array());
$testing = array();
while($rs = $select->fetch(PDO::FETCH_ASSOC)) {
$testing[] = array($rs['name'] => array('ip'=> $rs['ip'], 'port'=> $rs['port'], 'hosting'=> $rs['hosting']));
}
The result from this is:
array(2) {
[0]=>
array(1) {
["Google Web Search"]=>
array(3) {
["ip"]=>
string(10) "google.com"
["port"]=>
string(2) "80"
["hosting"]=>
string(19) "Hosted by The Cloud"
}
}
[1]=>
array(1) {
["Example Down Host"]=>
array(3) {
["ip"]=>
string(11) "example.com"
["port"]=>
string(2) "09"
["hosting"]=>
string(14) "ShittyWebHost3"
}
}
}
is there a way to make the bottom array the same as the top array, i dont want to edit the whole script, this seems easier.
You are appending a new integer indexed element with [] and then adding 2 nested arrays. Instead, add the name as the key:
$testing[$rs['name']] = array('ip'=> $rs['ip'],
'port'=> $rs['port'],
'hosting'=> $rs['hosting']);
Since you specify the columns in the query and they are the same as the array keys, then just this:
$testing[$rs['name']] = $rs;
When you assign a value to an array you use the syntax $arr[key] = $value. If you omit the key during the assignment, $value will be assigned to the next available integer key of the array, starting from 0.
This is an example of how it works:
$arr = array();
$arr[] = 'one';//Empty, so insert at 0 [0=>'one']
$arr[] = 'two';//Last element at 0, so use 1 [0=>'one',1=>'two']
$arr[6]= 'three';//Key is used, so use key [0=>'one',1=>'two',6=>'three']
$arr[] = 'four';//Max used integer key is 6, so use 7
print_r($arr);//[0=>'one',1=>'two',6=>'three',7=>'four']
So, when in your code you are using
$testing[] = array(
$rs['name'] => array(
'ip'=> $rs['ip'],
'port'=> $rs['port'],
'hosting'=> $rs['hosting']
)
);
You are assigning the newly created array to the positions 0,1,2,..N.
To avoid this, just specify the key explicitly, using the value you really want, like
$testing['name'] => array(
'ip'=> $rs['ip'],
'port'=> $rs['port'],
'hosting'=> $rs['hosting']
);
You can read more about arrays in the documentation
Side note
If you don't mind having an extra column in the generated arrays, you can rewrite entirely your code this way:
$query ="SELECT name, ip, port, hosting FROM sites";
$results = $conn->query($query)->fetchAll(PDO::FETCH_ASSOC);
$testing = array_column($results,null,'name');
It's slightly slower, but very handy in my opinion, PDOStatement::fetchAll retrieves all the data at once and array_column using null as second parameter does reindex the array with the wanted column as key.
PDOStatement::fetchAll
array_column

compare structure of php arrays regardless for content

I have two arrays that i want to compare their structure i.e, same keys.
I tried using array_diff_key but the problem is that one array is defined like this:
$fields = array('id' , 'site', 'placement', 'device', 'source', 'campaign', 'url', 'country', 'dof_count', 'dof_idx', 'active');
so when i use var_dump() on it i get this result:
{
[0]=>
string(2) "id"
[1]=>
string(4) "site"
[2]=>
string(9) "placement"
[3]=>
string(6) "device"
[4]=>
string(6) "source"
[5]=>
string(8) "campaign"
[6]=>
string(3) "url"
[7]=>
string(7) "country"
[8]=>
string(9) "dof_count"
[9]=>
string(7) "dof_idx"
[10]=>
string(6) "active"
}
and the other is created by a function and comes back like this:
{
["id"]=>
NULL
["site"]=>
NULL
["placement"]=>
NULL
["device"]=>
NULL
["source"]=>
NULL
["campaign"]=>
NULL
["url"]=>
NULL
["country"]=>
NULL
["dof_count"]=>
int(0)
["dof_idx"]=>
NULL
["active"]=>
NULL
}
so while the two arrays have the same structure, array_diff_key won't help. is there a way in php to compare this two array's structure while ignoring the content, which in my case it's all the null's and the one int in the second array?
You can simply use array_diff along with array_keys as
$result = array_diff($fields,array_keys($keys_array));
Note : Not Tested
I saw the other answers and for all I know they are correct. Those functions will be able to help you out.
But I couldn't understand why would you create your array like this:
$fields = array('id' , 'site', 'placement', 'device', 'source', 'campaign', 'url', 'country', 'dof_count', 'dof_idx', 'active');
If your objective was to simply verify the other array all along, then simply associatively create it:
<?php
$fields = array(
'id' => null,
'site' => null,
'placement' => null,
/*...*/
'active' => null
);
But still, I don't understand your need to verify the array structure, given that it should always be the same. If you have more than one input type for the array's then you should create a field called type on all of the arrays you are going to return and "if" them from there.
Example:
<?php
/*This array has a type and only two indexes of data.*/
$inputArray = array(
'type' => 'firstType',
'data1' => 'data',
'data2' => 'data'
);
/*This array also has a type but 6 indexes containing datas*/
$anotherInputArray = array(
'type' => 'secondType',
'data3' => 'data',
'data4' => 'data',
'data4' => 'data',
'data4' => 'data',
'data4' => 'data',
'data4' => 'data'
);
treatArray($inputArray);
treatArray($anotherInputArray);
function treatArray($array){
if($array['type']=='firstType'){
/*Treat it in one way*/
}elseif($array['type']=='secondType'){
/*Or the other way*/
}
}
I hope I could help, but you didn't describe the context you are working with, so I did my best to guess arround (even though it is not recommended).
Just array_flip your $field array:
var_dump(array_diff_key(array_flip($fields), $array2));

Authorize.Net-XML - Adding line items

First off thanks for writing this class. It has made life much easier for me in building applications.
I have CIM set up and I have no problem adding users, processing payments, etc. However I am stuck on adding line items. The examples on github use static population of the array used to create the XML request EX:
'lineItems' => array(
'itemId' => 'ITEM00001',
'name' => 'name of item sold',
'description' => 'Description of item sold',
'quantity' => '1',
'unitPrice' => '6.95',
'taxable' => 'true'
),
'lineItems' => array(
'itemId' => 'ITEM00002',
'name' => 'other name of item sold',
'description' => 'Description of other item sold',
'quantity' => '1',
'unitPrice' => '1.00',
'taxable' => 'true'
),
This works great if you are manually creating things but I am dynamically creating these line items based on user input. Unfortunately, I am unable do add multiple line items to the array due to the fact that the key ('lineItems') gets overwritten and I end up with one line item.
I have tried creating an array of lineItems and then merging it with no luck. Hopefully I am just missing a simple fix for this.
Thanks for responding John! Once again, great work on this class it has made my life much easier.
Here is what I ended up doing for simplicity. I am sure this can be expounded upon if necessary, but for me this worked perfect. Instead of passing multiple line items on the same level of the array I created line items as their own array and then modified setParamaters() to iterate through that array.
private function setParameters($xml, $array)
{
if (is_array($array))
{
foreach ($array as $key => $value)
{
if (is_array($value))
{
if($key == 'lineItems'){
foreach($value as $lineitems){
$line_item = $xml->addChild('lineItems');
foreach($lineitems as $itemkey => $itemvalue) {
$line_item->addChild($itemkey, $itemvalue);
}
}
}
else
{
$xml->addChild($key);
$this->setParameters($xml->$key, $value);
}
}
else
{
$xml->$key = $value;
}
}
}
}
This suited my needs perfectly and made it so I did not have to change anything on the front end except nesting the lineItems array. So the array I am sending looks more like this:
["lineItems"]=>
array(2) {
[0]=>
array(6) {
["itemId"]=>
string(9) "ITEM00010"
["name"]=>
string(21) "Blah Blah"
["description"]=>
string(21) "Blah Blah Description"
["quantity"]=>
string(1) "1"
["unitPrice"]=>
string(4) "100"
["taxable"]=>
string(5) "false"
}
[1]=>
array(6) {
["itemId"]=>
string(9) "ITEM00011"
["name"]=>
string(25) "Thing Thing"
["description"]=>
string(25) "Thing Thing Description"
["quantity"]=>
string(1) "2"
["unitPrice"]=>
string(3) "50"
["taxable"]=>
string(5) "false"
}
}
Also, for anyone out there looking to build the arrays for the line items I did this:
foreach ($services as $key => $service){
$line_items["lineItems"][] = array(
'itemId' => 'ITEM000'.$key,
'name' => $service->name,
'description' => $service->name,
'quantity' => $service_count[$key],
'unitPrice' => $service->price,
'taxable' => 'false'
);
}
And then just added it to the transaction_array that I passed to the AuthnetXML instance.
Thanks again!

I am the author of that class. The AuthnetXML class currently has a bug in it that results in the results you saw. You would need to make a change to core class to work around this.
I received an email from a user who offered a solution which I have not had a chance to review yet. I'll give you the same information they gave me and hopefully it helps you:
The problem is that you can't have duplicate keys at the same level in an array. If you do the last one entered wins and the rest are overwritten.
So you need a way to represent repeating items from XML in and array. I decide to use the JSON methods to keep it simple. A quick wat to convert Simple XML to and array is to pass it through JSON.
$array = json_decode( json_encode( $simpleXML), true);
That will convert XML like this:
<transactionSettings>
<setting>
<settingName>allowPartialAuth</settingName>
<settingValue>false</settingValue>
</setting>
<setting>
<settingName>duplicateWindow</settingName>
<settingValue>0</settingValue>
</setting>
<setting>
<settingName>emailCustomer</settingName>
<settingValue>false</settingValue>
</setting>
<setting>
<settingName>recurringBilling</settingName>
<settingValue>false</settingValue>
</setting>
<setting>
<settingName>testRequest</settingName>
<settingValue>false</settingValue>
</setting>
</transactionSettings>
To an array like this:
array(
'transactionSettings' => array(
'setting' => array(
0 => array('settingName' =>'allowPartialAuth' , 'settingValue' => 'false',),
1 => array('settingName' => 'duplicateWindow', 'settingValue' => '0', ),
2 => array('settingName' => 'emailCustomer', 'settingValue' => 'false', ),
3 => array('settingName' => 'recurringBilling', 'settingValue' => 'false',),
4 => array( 'settingName' => 'testRequest', false, ),
)
);
So you need to modify AuthNetXML.class to recognize this format. Just replace your setParameters() method with:
private function setParameters($xml, $array)
{
if (is_array($array))
{
$first = true;
foreach ($array as $key => $value)
{
if (is_array($value)) {
if( is_numeric($key) ) {
if($first){
$xmlx = $xml;
$first = false;
} else {
$parent = $xml->xpath('parent::*');
$xmlx = $parent[0]->addChild($xml->getName());
}
} else {
$xmlx = $xml->addChild($key);
}
$this->setParameters($xmlx, $value);
}
else
{
$xml->$key = $value;
}
}
}
}
UPDATE 2012-08-21
This bug has been fixed. Sample code has been updated.
EDIT: I've solved this issue. The lineItems key must be passed in like so:
'lineItems' => array(
'itemId' => '13',
'name' => 'hello',
'description' => 'hello description',
'quantity' => '1',
'unitPrice' => '55.00'
),
Note this differs from what's provided the samples over at the Authorize.net-XML repo. I'm going to head over there now and submit a fix.
ORIGINAL QUESTION:
I'm running into a similar problem involving the Authorize.net-XML class; when executing the createCustomerProfileTransactionRequest() method I receive the following error:
The element 'lineItems' in namespace 'AnetApi/xml/v1/schema/AnetApiSchema.xsd' has
invalid child element 'lineItem' in namespace
'AnetApi/xml/v1/schema/AnetApiSchema.xsd'.
List of possible elements expected: 'itemId' in namespace
'AnetApi/xml/v1/schema/AnetApiSchema.xsd'.' (length=272)
I've even gone so far as to paste in the sample input provided here, but receive the identical error? The class is otherwise working just fine; I use the createTransactionRequest() and createCustomerProfileRequest() methods to process AIM transactions and create CIM profiles without problem.
To reiterate, I'm even attempting to use identical sample input as that found on GitHub.
Any ideas?
Thanks so much!

PHP Remove elements from associative array

I have an PHP array that looks something like this:
Index Key Value
[0] 1 Awaiting for Confirmation
[1] 2 Assigned
[2] 3 In Progress
[3] 4 Completed
[4] 5 Mark As Spam
When I var_dump the array values i get this:
array(5) { [0]=> array(2) { ["key"]=> string(1) "1" ["value"]=> string(25) "Awaiting for Confirmation" } [1]=> array(2) { ["key"]=> string(1) "2" ["value"]=> string(9) "Assigned" } [2]=> array(2) { ["key"]=> string(1) "3" ["value"]=> string(11) "In Progress" } [3]=> array(2) { ["key"]=> string(1) "4" ["value"]=> string(9) "Completed" } [4]=> array(2) { ["key"]=> string(1) "5" ["value"]=> string(12) "Mark As Spam" } }
I wanted to remove Completed and Mark As Spam. I know I can unset[$array[3],$array[4]), but the problem is that sometimes the index number can be different.
Is there a way to remove them by matching the value name instead of the key value?
Your array is quite strange : why not just use the key as index, and the value as... the value ?
Wouldn't it be a lot easier if your array was declared like this :
$array = array(
1 => 'Awaiting for Confirmation',
2 => 'Asssigned',
3 => 'In Progress',
4 => 'Completed',
5 => 'Mark As Spam',
);
That would allow you to use your values of key as indexes to access the array...
And you'd be able to use functions to search on the values, such as array_search() :
$indexCompleted = array_search('Completed', $array);
unset($array[$indexCompleted]);
$indexSpam = array_search('Mark As Spam', $array);
unset($array[$indexSpam]);
var_dump($array);
Easier than with your array, no ?
Instead, with your array that looks like this :
$array = array(
array('key' => 1, 'value' => 'Awaiting for Confirmation'),
array('key' => 2, 'value' => 'Asssigned'),
array('key' => 3, 'value' => 'In Progress'),
array('key' => 4, 'value' => 'Completed'),
array('key' => 5, 'value' => 'Mark As Spam'),
);
You'll have to loop over all items, to analyse the value, and unset the right items :
foreach ($array as $index => $data) {
if ($data['value'] == 'Completed' || $data['value'] == 'Mark As Spam') {
unset($array[$index]);
}
}
var_dump($array);
Even if do-able, it's not that simple... and I insist : can you not change the format of your array, to work with a simpler key/value system ?
...
$array = array(
1 => 'Awaiting for Confirmation',
2 => 'Asssigned',
3 => 'In Progress',
4 => 'Completed',
5 => 'Mark As Spam',
);
return array_values($array);
...
$key = array_search("Mark As Spam", $array);
unset($array[$key]);
For 2D arrays...
$remove = array("Mark As Spam", "Completed");
foreach($arrays as $array){
foreach($array as $key => $value){
if(in_array($value, $remove)) unset($array[$key]);
}
}
You can use this
unset($dataArray['key']);
Why do not use array_diff?
$array = array(
1 => 'Awaiting for Confirmation',
2 => 'Asssigned',
3 => 'In Progress',
4 => 'Completed',
5 => 'Mark As Spam',
);
$to_delete = array('Completed', 'Mark As Spam');
$array = array_diff($array, $to_delete);
Just note that your array would be reindexed.
Try this:
$keys = array_keys($array, "Completed");
/edit
As mentioned by JohnP, this method only works for non-nested arrays.
I kinda disagree with the accepted answer. Sometimes an application architecture doesn't want you to mess with the array id, or makes it inconvenient. For instance, I use CakePHP quite a lot, and a database query returns the primary key as a value in each record, very similar to the above.
Assuming the array is not stupidly large, I would use array_filter. This will create a copy of the array, minus the records you want to remove, which you can assign back to the original array variable.
Although this may seem inefficient it's actually very much in vogue these days to have variables be immutable, and the fact that most php array functions return a new array rather than futzing with the original implies that PHP kinda wants you to do this too. And the more you work with arrays, and realize how difficult and annoying the unset() function is, this approach makes a lot of sense.
Anyway:
$my_array = array_filter($my_array,
function($el) {
return $el["value"]!="Completed" && $el!["value"]!="Marked as Spam";
});
You can use whatever inclusion logic (eg. your id field) in the embedded function that you want.
The way to do this to take your nested target array and copy it in single step to a non-nested array.
Delete the key(s) and then assign the final trimmed array to the nested node of the earlier array.
Here is a code to make it simple:
$temp_array = $list['resultset'][0];
unset($temp_array['badkey1']);
unset($temp_array['badkey2']);
$list['resultset'][0] = $temp_array;
for single array Item use reset($item)
