Question

EDIT: Parsed the array completely (it contained unparsed JSON!)

array(22) {
  [0]=>
array(4) {
["responseData"]=>
array(1) {
  ["translatedText"]=>
  string(163) "21558299 this is the text that i want to end up with, excluding the id number at the start of the string"
}
["responseDetails"]=>
string(0) ""
["responseStatus"]=>
int(200)

The string I want to search for is the 2155.. and IFF it’s present, I want to get the string that’s after it… How can I do this? Any help much appreciated! (Or a better solution…?)

What I need is a return boolean telling me if the ID is actually contained within array – if it is, I need the text. If it’s not, I need to know as I want to put some other text (not relevant here).

Disclaimer: Gonna give this one to nickb, he’s been beyond awesome.

EDIT: This part is irrelevant now:

This is what I got so far, but it’s returning null. $trans_json is the array quoted above. $search[id] is another array, that holds the id string.

$return = array_filter( $trans_json, function($el) { 
    if( !( $start = strpos( $el, $search[id]) === false)) {
            $str =  substr( $el, $start);
            return substr( $str, 0, strpos( $str, '}'));
    }
            return null;
    });

Use array_walk():

Your example isn’t working because $search is undefined. You need a closure (note the use ($search):

$search['id'] = '2s5d56b9712';
$return = array_walk( $trans_json, function( &$el) use( $search) { 
    if( !( ($start = strpos( $el, $search['id'])) === false)) {
        $str =  substr( $el, $start);
        $el = substr( $str, strlen( $search['id']) + 1, strpos( $str, '}'));
    }
});

var_dump( $trans_json);
