ARRAY_SEARCH
array_search —
Searches the array for a given value and returns the corresponding key if
successful
Description
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.
Note: If needle
is a string, the comparison is done in a case-sensitive manner.
If the optional
third parameter strict is set to TRUE then the array_search()
will also check the types of the needle in the haystack.
If needle
is found in haystack more than once, the first matching key is returned.
To return the keys for all matching values, use array_keys() with the optional search_value
parameter instead.
'blue', 1 => 'red', 2 => 'green', 3 => 'Red');
$key = array_search('green', $array); // $key = 2;
echo $key;
$key = array_search('Red', $array, true); // $key = 3;
echo $key;
?>
