As of PHP 5.4 we can create new arrays in a simple way. Simpler than ever. The following code sample shows that.
<?php $vec_a = [4,6,2,7]; $vec_b = ['a'=>'australia','b'=>'belgium','c'=>'canada']; foreach($vec_a as $k=>$v) { echo " ".$k."=>".$v; } foreach($vec_b as $k=>$v) { echo " ".$k."=>".$v; } ?>
The following video clip shows the execution of this code sample and explains it.
