Question

I want to create an array with a message.

$myArray = array('my message'); 

But using this code, myArray will get overwritten if it already existed.

If I use array_push, it has to already exist.

$myArray = array(); // <-- has to be declared first. array_push($myArray, 'my message'); 

Otherwise, it will bink.

Is there a way to make the second example above work, without first clearing $myArray = array();?

Answer 1

Check if the array exists first, and if it doesn’t, create it…then add the element, knowing that the array will surely be defined before hand :

if (!isset($myArray)) {     $myArray = array(); }  array_push($myArray, 'my message');
