[RESOLVED] Finding specific array key

[kingbeastie]

Hi,

I have an array with sub arrays, example:

$an_array =
array([0] => ([id] => 152 [otherstuff] => blah... )
([1] => ([id] => 167 [otherstuff] => yadda... )
([2] => ([id] => 17 [otherstuff] => stuff... );

I have a variable that stores an id, how can I get the key of the specific array, ie:

$x = 0;
$var = 152;
if($an_array['id'] == $var){
$x = get_this_array_key;
}

I don't know how to get the key of the array where I have the 'id' value of that array

Can anyone help please,

Thanks

One way is to do a manual linear search:

$value = 152;
$x = false;
for ($i = 0; $i < count($an_array); ++$i) {
    if ($an_array[$i]['id'] == $value) {
        $x = $i;
        break;
    }
}

Ha ha!!

Dude thank you so much for that, I had specific elements of a session array that could be adjusted by the user and it was only updating the first entry thus I had to find the specific part of the array to be updated.

Thanks again, much appreciated.
