The answer is yes, thanks to the handy array_search function which searches an array for a given value and returns the corresponding key if the search is successful, and false if the value isn’t found in the array.
$array = array(0 => 'blue', 1 => 'red', 2 => 'green', 3 => 'red'); $key = array_search('green', $array); // $key = 2; $key = array_search('red', $array); // $key = 1;
(Note that similar to strpos validations, you need to make use of the === operator when testing the return value of this function).
The array_search returns the first match it comes across, meaning that if the value is in the array, you’ll only know of one instance. If it is important to know all of the corresponding keys where the value can be found, rather use the array_keys function, but this time with the optional search parameter.
$array = array("blue", "red", "green", "blue", "blue"); print_r(array_keys($array, "blue")); /* returns: Array (  => 0  => 3  => 4 ) */

Living in the beautiful coastal town of Gordon's Bay in South Africa, he games, develops, takes in animated fare, trains under whichever martial arts dojo is closest at the time, and for the most part, simply enjoys life with his amazing wife and daughter.
Oh, and he draws ever now and then too.
This is a collection of things that he has managed to find the time to scribble down since 2007.
