How to extract PHP array values and remove data - php

Question

I have seen a bunch of ways, but none that seem to work. My array data is coming back like this.
Array
(
[0] => RESULT=0
[1] => RESPMSG=Approved
[2] => SECURETOKEN=8cpcwfZhaH02qNlIoFEGZ1wO4
[3] => SECURETOKENID=253cad735251571cebcea28e877f4fd7
I use this:
<?php echo $response[2];?>
too get each out, that works. But I need to remove “SECURETOKEN=” so im left with just the number strings. I have been trying something like this with out success.
function test($response){
$secure_token = $response[1];
$secure_token = substr($secure_token, -25);
return $secure_token;
}
Also Im putting end number into a form input “Value” field. Not that that matters, unless it does?
Thanks

Answer 1

This is what I would do:
$keyResponse = [];
foreach ($response as $item) {
list($k, $v) = explode('=', $item, 2);
$keyResponse[$k] = $v;
}
Now you can easily access just the value part of each item based on the name:
echo $keyResponse['SECURETOKEN']; // output: 8cpcwfZhaH02qNlIoFEGZ1wO4
The advantage to this method is the code still works if the order of the items in $response changes

Answer 2

I get your secure token like this (tested):
<?php
$arr = array(
'RESULT=0',
'RESPMSG=Approved',
'SECURETOKEN=8cpcwfZhaH02qNlIoFEGZ1wO4',
'SECURETOKENID=253cad735251571cebcea28e877f4fd7'
);
$el = $arr[2];
$parts = explode('=', $el);
echo '#1 SECURETOKEN is ' . $parts[1];
// This break just for testing
echo '<br />';
// If you wanted to, you could revise the whole array
$new = array();
foreach( $arr as $el ){
$parts = explode('=', $el);
$new[$parts[0]] = $parts[1];
}
// Which would mean you could then get your securetoken like this:
echo '#2 SECURETOKEN is ' . $new['SECURETOKEN'];
