Extract takes an array and moves their keys onto the local symbol table. So extract( ['src' => 'myimg.jpg', 'alt' => 'My alt']); echo $src; // myimg.jpg echo $alt; // My alt Using extract on an array with numeric keys gives you fun stuff like $0, $1 and so on. Extract sees most of its use in PHP based template management classes where an associative array is extracted than a template file is included, to allow the template file to use the key names as variables rather than the array syntax.

It's kinda neat to be honest.
