I am using this code below but although I have the same domain twice only one output it echoing on the page.
$urls = array(
'phpclasses.org' => 'phpclass',
'phpclasses.org' => 'php',
'php.com' => 'php'
);
$RankChecker=new RankChecker(1,5);
foreach($urls as $url => $keyword) {
$result=$RankChecker->find($url,$keyword);
if ($result!==false) {
echo $url . " is found at page number ".$result["page"].".";
echo '<br>';
}
}
I need to be able to use same url multiple times.
Why is this not working on the code above?
You can't have an array with the same key twice. How would you access the value you wanted by key if it wasn't unique?
You need to try some other structure for your array.
E.g
$urls = array(
0 => array('url' => 'phpclasses.org', 'keyword' => 'phpclass'),
1 => array('url' => 'phpclasses.org', 'keyword' => 'php'),
2 => array('url' => 'php.com', 'keyword' => 'php')
);
Then you would need to call your function like $result=$RankChecker->find($keyword['url'],$keyword['keyword']); in the loop.
You are overwriting the value of the key 'phpclasses.org'. Doing
$urls = array(
'phpclasses.org' => 'phpclass',
'phpclasses.org' => 'php'
);
is essentially the same as
$urls = array(
'phpclasses.org' => 'phpclass'
);
$urls['phpclasses.org'] = 'php';
In the end, there will only be one key for 'phpclasses.org' in the array
Think about changing it to a multidimensional array, removing the dependance on the key

I am new in PHP. I am working for send data using PHP API. Its method is like below
$createContact->setCustomFieldValues(
[
array(
'customFieldId' => 'pcVFD6',
'value' => array('35')
),
array(
'customFieldId' => 'pcVnzW',
'value' => array('37')
)
]
);
I have data in array like this
$aa = array("pcVFD6"=>"35", "pcVnzW"=>"37");
I want pass this values to above function but I am not getting idea about proper way to do it.
I have tried something like this
foreach ($aa as $key => $value){
$createContact->setCustomFieldValues([
array(
'customFieldId' => $key,
'value' => array($value)
)
]
);
}
its working but passing only last one array to API. Anyone here can please help me for achieve my goal?
Thanks!
You need to transform the array before you pass it to setCustomFieldValues. You don't want to be calling setCustomFieldValues multiple times as your current attempt does, as that's not equivalent to the original. You just need to change the structure of the array ahead of time.
For example:
$aa = array("pcVFD6"=>"35", "pcVnzW"=>"37");
$transformedArr = array();
foreach ($aa as $key => $value){
$transformedArr[] = array(
'customFieldId' => $key,
'value' => array($value)
);
}
$createContact->setCustomFieldValues($transformedArr);
im currently trying to generate a dynamic subnavigation. Therefor i pull data off of the database and store some of it an an array. Now i want to do an foreach in this array. Well as far as I know, this isn't possible.
But maybe I'm wrong. I would like to know if it would be possible, and if so how do i do it?
This is my code, which wont work since it hands out an syntax error.
$this->subnav = array(
'' => array(
'Test Link' => 'login.php',
'Badged Link' => array('warning',10023,'check.php')
),
'benutzer' => array(
'Benutzer suchen' => '/mother/index.php?page=benutzer&subpage=serach_user',
'Benutzer hinzufügen' => '/mother/index.php?page=benutzer&subpage=add_user',
'Rechtevergabe' => '/mother/index.php?page=benutzer&subpage=user_rights'
),
'logout' => array(
'Login' => '/mother/login.php',
'Logout' => '/mother/index.php?page=logout'
),
'datenbank' => array(
(foreach($this->system->get_databases() as $db){array($db->name => $db->url)}),
'Deutschland' => '/mother/login.php',
'Polen' => '/mother/index.php',
'Spanien' => '/mother/index.php',
'Datenbank hinzufügen' => '/mother/index.php?page=datenbank&subpage=add_database'
)
);
}
You can't place foreach loop inside an array like this. You can do something like this though.
foreach($this->system->get_databases() as $db)
{
$this->subnav['datenbank'][$db->name] = $db->url;
}
This is not possible. but you can do it in other way like you can place the foreach outsite and top of this array and assign to an array and then you can use that array variable.
e.g.
$arrDB = array();
foreach($this->system->get_databases() as $db) {
$arrDB[$db->name] = $db->url;
}
Now assign it to:
'datenbank' => $arrDB
How do I push arrays inside the "adjacencies" key value pair that should have an encapsulated array holding the "arrays" (ie. array(("nodeTo" => "$to"),("nodeTo" => "$to"))) without overwriting them and appending them similiar to "+=". also the push into the key "adjacencies" doesnt seem to pick up the value.
$node[] = array(
"adjacencies" => array(), //inside this array should go all the arrays seprated by commas.
"data" => array(
"color" => $color1,
"type" => $type1
);
// this push doesnt seem to detect the adjacencies value and doesnt really push the array inside of the container array. I also tried $node["adjacencies"][]=array("nodeTo" => "$to"); but it didnt work
$node["adjacencies"]=array("nodeTo" => "$to");
}
If you want multiple arrays within 'adjacencies', append them to the end of the array:
$node[0]['adjacencies'][] = array("nodeTo" => "$to");
Granted, you'll need to know which $node index to work with (if there are multiple nodes).
Edit:
After reading the comments, it looks like the OP's desired array structure is this:
$node = array(
'adjacencies' => array(),
'data' => array(
'color' => $color1,
'type' => $type1,
);
);
Thus, to append additional nodes to the adjacencies array, you can do this:
$node['adjacencies'][] = array('nodeTo' => "$to");
By the way you use $node in the second statement I think you meant:
$node = array(
not:
$node[] = array(
// ^^
Then you can push the array by doing:
$node['adjacencies'][] = array('nodeTo' => $to);
I am not very familiar with this type of array. How do i push another set of data in this type of array?
$array = array(
array(
'service_name' => $row['application_name'],
'html_id' => $row['html_id'],
'url' => $row['url']
)
);
as far as I understood-
$array[]= array(
'service_name' => $row['application_name'],
'html_id' => $row['html_id'],
'url' => $row['url']
);
will add another section, same as first
This adds another array to the outhermost array:
$array[] = array('key' => 'value', 'key2' => 'value2');
Always take the path of the PHP man my friend :) http://php.net/manual/en/function.array-push.php
it depends on which array you want to put data into :) - the first one is a classical array and the included one is an associative array
The answer really depends on what the application or API is expecting but to take a wild stab at it, something like -
<?php
$array = array (
array (
'service_name' => $row['application_name'],
'html_id' => $row['html_id'],
'url' => $row['url']
),
array (
'service_name' => 'app2',
'html_id' => 'htmlid2',
'url' => 'url2'
)
);
I would like to retrieve the first key from this multi-dimensional array.
Array
(
[User] => Array
(
[id] => 2
[firstname] => first
[lastname] => last
[phone] => 123-1456
[email] =>
[website] =>
[group_id] => 1
[company_id] => 1
)
)
This array is stored in $this->data.
Right now I am using key($this->data) which retrieves 'User' as it should but this doesn't feel like the correct way to reach the result.
Are there any other ways to retrieve this result?
Thanks
There are other ways of doing it but nothing as quick and as short as using key(). Every other usage is for getting all keys. For example, all of these will return the first key in an array:
$keys=array_keys($this->data);
echo $keys[0]; //prints first key
foreach ($this->data as $key => $value)
{
echo $key;
break;
}
As you can see both are sloppy.
If you want a oneliner, but you want to protect yourself from accidentally getting the wrong key if the iterator is not on the first element, try this:
reset($this->data);
reset():
reset() rewinds array 's internal
pointer to the first element and
returns the value of the first array
element.
But what you're doing looks fine to me. There is a function that does exactly what you want in one line; what else could you want?
Use this (PHP 5.5+):
echo reset(array_column($this->data, 'id'));
I had a similar problem to solve and was pleased to find this post. However, the solutions provided only works for 2 levels and do not work for a multi-dimensional array with any number of levels. I needed a solution that could work for an array with any dimension and could find the first keys of each level.
After a bit of work I found a solution that may be useful to someone else and therefore I included my solution as part of this post.
Here is a sample start array:
$myArray = array(
'referrer' => array(
'week' => array(
'201901' => array(
'Internal' => array(
'page' => array(
'number' => 201,
'visits' => 5
)
),
'External' => array(
'page' => array(
'number' => 121,
'visits' => 1
)
),
),
'201902' => array(
'Social' => array(
'page' => array(
'number' => 921,
'visits' => 100
)
),
'External' => array(
'page' => array(
'number' => 88,
'visits' => 4
)
),
)
)
)
);
As this function needs to display all the fist keys whatever the dimension of the array, this suggested a recursive function and my function looks like this:
function getFirstKeys($arr){
$keys = '';
reset($arr);
$key = key($arr);
$arr1 = $arr[$key];
if (is_array($arr1)){
$keys .= $key . '|'. getFirstKeys($arr1);
} else {
$keys = $key;
}
return $keys;
}
When the function is called using the code:
$xx = getFirstKeys($myArray);
echo '<h4>Get First Keys</h4>';
echo '<li>The keys are: '.$xx.'</li>';
the output is:
Get First Keys
The keys are: referrer|week|201901|Internal|page|number
I hope this saves someone a bit of time should they encounter a similar problem.
