Push Associate array into another array - php

I would like to push an associate array into another array but I an not sure how to go about it. At the minute I have the following:
$rate_info = array(
"hotel_rating" => $hotel->{'hotelRating'},
"room_rate" => $hotel->{'RoomRateDetailsList'}->{'RoomRateDetails'}->{'RateInfo'}->{'ChargeableRateInfo'}->{'#total'},
"currency" => $hotel->{'RoomRateDetailsList'}->{'RoomRateDetails'}->{'RateInfo'}->{'ChargeableRateInfo'}->{'#currencyCode'},
"deep_link" => $hotel->{'deepLink'}
);
array_push($hotel_array[$hotel->{'name'}]["offers"], "expedia" => $rate_info );
"Offers" is an array , all I want to do is add an key value with an array within in. Any ideas? All I seem to be getting at the minute is parse errors.
UPDATE
This is the output of the array so far
["offers"]=>
array(2) {
["LateRooms"]=>
array(4) {
["hotel_rating"]=>
int(4)
["room_rate"]=>
string(6) "225.06"
["currency"]=>
string(3) "USD"
}
[0]=>
string(4) "test"
}
As you can see instad of [0] I would like ["site"]=>array()
Thanks

I'd do this for the array assignment:
$hotel_array[$hotel->name]['offers']['expedia'] = $rate_info;
Ensure your warnings are enabled, so you know arrays (and subarrays) have been set up before you use them.

Did you first do this?
$hotel_array[$hotel->{'name'}] = array();
And then you can do:
array_push($hotel_array[$hotel->{'name'}]["offers"], "expedia" => $rate_info );

How to store associative array in Laravel

I'm new to Laravel, and I want to store this array in DB.
This is the php code of my array:
$socialNetwork = array();
$socialNetwork[0]["name"]= "Facebook";
$socialNetwork[0]["account"]= "facebook_account";
$socialNetwork[1]["name"]= "Twitter";
$socialNetwork[1]["account"]= "twitter_account";
$socialNetwork[2]["name"]= "Instagram";
$socialNetwork[2]["account"]= "insta_account";
The var_dump() looks like this:
array(3) {
[0] => array(2) {
["name"] => string(8) "Facebook"
["account"] => string(16) "facebook_account"
}
[1] => array(2) {
["name"] => string(7) "Twitter"
["account"] => string(15) "twitter_account"
}
[2] => array(2) {
["name"] => string(9) "Instagram"
["account"] => string(13) "insta_account"
}
}
I've tried several things but I can't get it to work!
Please help with the code. The table name is socialAccounts
Add a column in your database for this field; a JSON or TEXT type will do the job.
Next, you should add the column to the $casts array on your SocialAccount model:
protected $casts = [
'facebook_account' => 'array',
];
Now, whenever you retrieve this value, it will be deserialized for you.
To store the value, just use json_encode():
$social_account->facebook_account = json_encode($facebookArrayData);
$social_account->save();
You can read more on attribute casting in the docs; https://laravel.com/docs/7.x/eloquent-mutators#attribute-casting

Get an EXACT value in $_POST array

I'm studying php and I'm trying to figure out how to get the string "Juve_Milan" from this var_dump($_POST) :
array(5) {
["Juve_Milan"] => array(2) {
[0] => string(1)
"5" [1] => string(1)
"1"
}["Inter_Roma"] => array(2) {
[0] => string(1)
"4" [1] => string(1)
"4"
}["Napoli_Lazio"] => array(2) {
[0] => string(1)
"2" [1] => string(1)
"5"
}["name"] => string(0)
"" ["submit"] => string(5)
"Invia"
}
I could get all of them with:
foreach ($_POST as $param_name => $param_val) {
echo "<tr><td>".$param_name."</td><td>".$param_val[0]."-".$param_val[1]."</td></tr>";
}
But i want to get them exactly one by one, for example, if i want to get the string "Juve_Milan" or "inter_Roma" how can i do?
Without looping, how can i get the string value: "Juve_milan" or "Inter_Roma"? Becouse with the loop i can access them this way : $_POST as $param_name => $param_val
But i want to get them without loop, my first attempt was something like $_POST[0][0] but its wrong...
There are numbers of php array functions you can use.
You can use
array shift
to remove an element from an array and display it .e.g
$club = ['juve_millan', 'inter_roma', 'napoli_lazio'];
$juve = array_shift($club);
echo $juve;// 'juve_millan'
but note that the array is shortened by one element i.e. 'juve_millan' is no more in the array and also note that using
array_shift
over larger array is fairly slow
Array Slice function
PHP
array_slice()
function is used to extract a slice of an array e.g
$club = ['juve_millan', 'inter_roma', 'napoli_lazio'];
if I want to display
inter_roma
or assigned it to a variable, then I can do this
$roma = array_slice($club, 1, 1);// The first parameter is the array to slice, the second parameter is where to begin(which is one since most programming language array index start from 0 meaning juve_millan is zero, while inter_roma is 1, napoli_lazio is 2) and the length is 1 since i want to return a single element.
I hope you understand
You could iterate over keys of the main array like this:
foreach($_POST as $param_name => $param_val) {
echo "<tr><td>".$param_name."</td></tr>";
}
This will return each Juve_Milan, Inter_Roma etc. one by one. Although it's part of the code you already have, I believe this will return values you want only.

Php sorting multidimensional array?

How to sort the following array?
I have an multidimensional array that gets filled with total hours for each brand
$totalHours = array(
'brand' => array(),
'project' => array(),
'hours' => array()
);
The output is something like this (project is not filled):
array(3) {
["brand"]=>
array(3) {
[0]=>
string(4) "Nike"
[1]=>
string(9) "Coke Cola"
[2]=>
string(8) "Converse"
}
["project"]=>
array(3) {
[0]=>
string(6) "Bonobo"
[1]=>
string(4) "LDRU"
[2]=>
string(2) "US"
}
["hours"]=>
array(3) {
[0]=>
int(28)
[1]=>
int(106)
[2]=>
string(1) "2"
}
}
Now I would like to sort the array based on the "hours" field.
I've tried the array_multisort but it seems like I simply don't get how this function works and how to apply it to this array.
I have been able to sort an single array with just one row of values. If I apply that to this problem im sorting only the hours field, leaving the others unsorted and therefore the array is corrupted.
The "project" does actually contains a string. It always does. In this example I didn't filled it.
array_multisort should work:
$totalHours = array(
'brand' => array('Nike', 'Coke Cola', 'Converse'),
'project' => array(),
'hours' => array(28, 106, '2')
);
array_multisort($totalHours['hours'], $totalHours['brand']);
var_dump($totalHours);
That data format is not very convenient because there is no direct association between brands and hours, they even sit in different arrays! Plus, the last hour is a string, not an integer.
We're going to have to create an intermediate array to associate them and sort them. We'll then re-inject everything in the original array.
// Make sure both arrays of brands and hours and the same size
if (count($totalHours['brand']) != count($totalHours['hours'])) {
throw new Exception('Invalid data!');
}
// Make sure every hour record is an integer, not a string
$totalHours['hours'] = array_map('intval', $totalHours['hours']);
// array_combine will sort all arrays based on the sorting of the first one
array_multisort($totalHours['hours'], $totalHours['brand'], $totalHours['project']);
EDIT: Using array_multisort was #delprks 's idea originally. Here I applied it to both brand and project arrays.
You cant do that with a single array_* function!
if (project is not filled) always and the indexes of brand and hours are equal, then you can do:
$forsort = array_combine($totalHours["brands"],$totalHours["hours"]);
asort($forsort,SORT_NUMERIC);
$totalHours["brands"]=array_keys($forsort);
$totalHours["hours"]=array_values($forsort);
But, this is just an answer for you question, not best practise at all.

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)

Get specific key value pair from multidimensional array

I have the following array:
array(2) {
[0] => array(3) {
["submission_id"] => int(28)
["date"] => string(22) "2010-10-18 15:55:33+02"
["user_id"] => int(12)
}
[1] => array(3) {
["submission_id"] => int(37)
["date"] => string(22) "2010-11-21 16:02:07+01"
["user_id"] => int(23)
}
I want to get only the user_id key values from this array. I could obviously loop over it, but I was wondering if there was a quicker way.
You could use array_map (might not be quicker though, as it will make a function call per array element):
function getUserId($a) {
return $a['user_id'];
}
$user_ids = array_map('getUserId', $array);
Apart from that, looping is the only way (array_map makes loop anyway).
You can access only the user_id values like this if you know the array index you want to access:
$arr = your array here..
echo $arr[0]['user_id'];
echo $arr[1]['user_id'];
