PHP version: 5.2SVN-2009-11-10 (SVN)
PHP Bug Type: Arrays related
Bug description: array_search() false postive
Description:
------------
The specified code produces, at least as I see it, a false positive.
Needle and haystack values are of the same type and the matching value has
a different last character.
When I enforce the type test by setting the strict parameter to true,
the result is correct : Not found.
(I tested this on different PHP 4.X and 5.X installations on Windows and
Linux, all produce the same result)
Reproduce code:
---------------
$arr_ean=array('333333333333333333','541448820060826105','444444444444444444');
$pos=array_search('541448820060826106',$arr_ean);
if($pos===FALSE) {
echo "Not found";
} else {
echo "Found at key : $pos";
}
Expected result:
----------------
Not found
Actual result:
--------------
Found at key : 1
