global keyword in php

[colap]

It's a function=>

 

function _wp_call_all_hook($args) {
global $wp_filter;
//var_dump($wp_filter);
//exit();

reset( $wp_filter['all'] );
do {
	foreach( (array) current($wp_filter['all']) as $the_ )
		if ( !is_null($the_['function']) )
			call_user_func_array($the_['function'], $args);

} while ( next($wp_filter['all']) !== false );
}

 

Why is $wp_filter variable declared as global ? Was $wp_filter assigned before ?

I'm assuming this is a word press function? with which I'm not familiar. However globals should be avoided, it should be passed as argument to the function.

WordPress is a piece of crap under the hood.  Well written PHP never has the 'global' keyword in it.

Agreed. It's a very poorly designed application/framework. It's just a shame it works so well and is so easy to customize.
