It's not quite what you're asking for, but there is a way to handle array results from functions where you know the number of elements that will be returned.
For example:
// explode splits the string on the provided boundary
// and returns an array containing each segment.
// using list() we can assign the two segments to two
For example:
// explode splits the string on the provided boundary
// and returns an array containing each segment.
// using list() we can assign the two segments to two
// variables within the same statement
$size = "1000x1000";
list( $width, $height ) = explode( "x", $size );
