If you have a PHP function that accepts a lot of arguments sometimes it would be easier just to pass those arguments into that function as an array, with the array keys acting as individual arguments.
If you create a function like this and then try to pass the array into it, it will not preserve all the default assigned keys.
function example($args = array( 'foo' => 'boom', 'bar' => 'pow' )) { // } |
Here is a handy tool that allows you to have defaults.
/* * Required to set/merge array key/vals */ function parse_argument_array($args, $defaults='') { /* Check if Array is passes */ if (is_array( $args )) { $arr =& $args; } else { /* parse_str converts string to array */ parse_str($args, $arr); } /* * If $defaults=array, merge missing/replaced * http://php.net/manual/en/function.parse-str.php */ if (is_array($defaults)) { return array_merge($defaults, $arr); } return $arr; } /* * Your function that accepts an array as an argument */ function function_with_argument_array($args='') { /* * Default Settings */ $defaults = array( 'foo' => 'boom', 'bar' => 'pow' ); $args = parse_argument_array($args, $defaults); return $args; } |
// On its own print_r(function_with_argument_array()); |
Prints
Array
(
[foo] => boom
[bar] => pow
)
// With Arg print_r(function_with_argument_array(array( 'foo' => 'bang' ))); |
Prints
Array
(
[foo] => bang
[bar] => pow
)
