Using an associative array as php function's input in PHP Server Side Scripting Language?
Answer(s) available: 1
why not write all functions this way?"
For that matter, why not forget about parameters completely, and use global variables for everything? (kidding)"
Passing an associative array has one useful advantage: you can make multiple function parameters optional, and you can pass a value for the Nth parameter without having to pass a value for the *N-1*th parameter."
But you have no way to make mandatory parameters with a compile-time error if you don't pass them. Neither can you declare type-checking."
You'll have to write code inside the called function to check for the presence and the type of required parameters."
An alternative I have used is to declare conventional parameters for those that are mandatory, and then as the last (optional) argument, declare an associative array called
$options that contains only the optional items.
function database_connect($dbname, $user, $password, array $options = array())"
