[PHP] [RE] array_search From: Gyozo Papp (pgerzson <email protected>)
Date: 06/21/01

Hello,

you mixed array_search(...) with in_array(...).
<manual>
mixed array_search (mixed needle, array haystack, bool strict)

Searches haystack for needle and returns the key if it is found in the array, FALSE otherwise.
</manual>

Therefore, in the 1st example it returns 0 and it was converted to FALSE by PHP, so you didn't get the expected result. You should test if there is any match in the array:

if(($key = array_search("val1",$myarray)) !== false)
{
    print "Value found at :". $key;
}
