nested array...

hi, i have a nested array
ex:
print_r($nestedarray):
Array(
[0]=>Array([id]=>1 [name]=>name1 [etc]=>etc1)
[1]=>Array([id]=>2 [name]=>name2 [etc]=>etc2)
[3]=>Array([id]=>3 [name]=>name3 [etc]=>etc3)
)

if I want to check whether id=5 is in that $nestedarray, how to do that?!?!

i'd really appreciate the help..

thanks in advance..

foreach($nestedarray as $arr) {
if($arr['id'] == 5)
echo 'Found id 5';
}

$nestedarray[$i['id'] == 5

and $i is your array index

<?php
foreach ($nestedarray as $v) {
if ($v['id'] == 5) {
$in_array = true;
break;
}
}
?>

I would have built the arrays with the ID as the index in the first
place, and then used http://php.net/isset, but maybe that's just me...

You could mess with in_array I suspect, or write an array_map that
stores the ID when you hit it...
