(PHP 4 )
in_array -- Return TRUE if a value exists in an array
Description
bool in_array (mixed needle, array haystack [, bool
strict])
Searches haystack for
needle and returns TRUE
if it is found in the array, FALSE otherwise.
If the third parameter strict is set to
TRUE then the in_array()
will also check the types of the needle
in the haystack.
Example 1. In_array() example
$os = array ("Mac", "NT", "Irix", "Linux");
if (in_array ("Irix", $os)){
print "Got Irix";
}

Example 2. In_array() with strict example
// This will output:
1.13 found with strict check
