PHP - Remove arrays by its value

Question

Here's the array i have , and i wanted to modify it the way i needed.

i need the above array parents to remove , and the child values saved, like this one :

Array
(
    [0] => Array
        (
            [ip] => 127.0.0.1
            [php_session] => d9r2qfeiheo0gfklcq7vbj9nq7
            [timestamp] => 1402593151
        )
    [1] => Array
        (
            [ip] => 127.0.0.1
            [php_session] => d9r2qfeiheo0gfklcq7vbj9nq7
            [timestamp] => 1402593194
        )   
   [2] => Array
       (
           [ip] => 127.0.0.1
           [php_session] => d9r2qfeiheo0gfklcq7vbj9nq7
           [timestamp] => 1402593249
       )     
    [3] => Array
        (
            [ip] => 127.0.0.1
            [php_session] => d9r2qfeiheo0gfklcq7vbj9nq7
            [timestamp] => 1402593303
        )

    [4] => Array
        (
            [ip] => 127.0.0.1
            [php_session] => d9r2qfeiheo0gfklcq7vbj9nq7
            [timestamp] => 1402593308
        )

    [5] => Array
        (
            [ip] => 127.0.0.1
            [php_session] => d9r2qfeiheo0gfklcq7vbj9nq7
            [timestamp] => 1402593309
        )

    [6] => Array
        (
            [ip] => 127.0.0.1
            [php_session] => d9r2qfeiheo0gfklcq7vbj9nq7
            [timestamp] => 1402593309
        )
)

after this , i want to modify the result array to remove any key that have the same ip and php_session value. any ideas out there ?

Just curious, but have you tried to solve this? Perhaps even a simple foreach loop? — Jonathan Kuhn

@JonathanKuhn , yes , i did some research about it , i found tons of answers but non of the answers solved my issue. most helpful answer i got was the RecursiveIteratorIterator function , but still not doing exact what i wanted. — Saeid Khaleghi

Just make 2 foreach loops like so:

<?php
$beginArray = array(
    array(
        array(
            'ip' => '127.0.0.1',
            'php_session' => 'abcde',
            'timestamp' => 'abce'
        )
    ),
    array(
        array(
            'ip' => '127.0.0.1',
            'php_session' => 'abcde',
            'timestamp' => 'abce'
        )
    ),
    array(
        array(
            'ip' => '127.0.0.1',
            'php_session' => 'abcde',
            'timestamp' => 'abce'
        )
    ),
);


foreach($beginArray as $array) {

    foreach($array as $arr) {
        $resultArray[] = $arr;
    }

}
var_dump($resultArray);
?>

Anyways: Take better names for the variables. :)

Nice one , but what about matching arrays with its value ? something like remove array where ip == 127.0.0.1 and php_session == abcde ? and what do u mean by Take better names for the variables , do i set these bad or wrong or something?

No haha, I mean don't take my variable names '$array' '$resultArray' '$arr'.

You will probably have to work with array_search() then.
