array_search problem

[poring]

I'm trying to use array_search to check if an element is in an array, but the problem is that it returns false if the element exists in first position.

My code is:

$blah = array ('a', 'h', 'k');

$searchfor = 'a';

if (array_search ($searchfor, $blah, true)) echo "it's in there";

How do I fix this? thanks

Check the manual for array_intersect(). Might help.

Hmm.. it doesn't help much.. but thanks anyway

Try

if(array_search(...)!==false){...}

to check that the result isn't something that might just look like false (i.e., zero).

it may give you some idea

<?php

$blah = array ('a', 'h', 'k');

$searchfor = 'a';
$max = sizeof($blah);

for($i=0; $i < $max; $i++)
{
if ($blah[$i] == $searchfor)
echo "it's in there";
}

?>

...or use in_array() - you don't care where it is in the array, you just want to know if it is.
