PHP Array functions.
A (hopefully useful) list of some array functions, what they do, and an example usage.
|array()||Creates arrays and hashes.||$desserts = array("chocolate", "icecream");|
$appliances = array("fridge" => "Kelvinator", "toaster" => "Sunbeam");
|sizeof()||Returns the number of array elements.||sizeof($desserts); |
// Returns 2 in this case.
|is_array()||Test if a variable is an array.||is_array($desserts); |
// Returns true, since $desserts is an array.
|range()||Automatically create an array containing a range of elements||$letters = range("b", "f");|
// Returns: ("b", "c", "d", "e", "f")
|array_values()||Returns an array of a hashes values.||$values = array_values($hash-array);|
|array_keys()||Returns an array of a hashes keys.||$keys = array_keys($hash-array);|
|array_search()||Find value in array, returns key or list number.||array_search("lookfor", $in);|
|in_array()||Returns true or false if an array contains a specific value.||in_array("lookfor", $in);|
|extract()||Extracts list items into matched variable/value pairs.||extract($deserts); |
// Returns variabes named as the hash keys.
|list()||Assigns list values to variables.||list($a, $b) = $desserts;|
