nested array...

["opo jal" <penjahat.jahat@xxxxxxxxx>]

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..
