Does a PHP array need to be declared before use?

Question

While writing a recent application I accidentally started filling an array before I had declared it.

error_reporting ( E_ALL);  
$array[\'value\'] = \'Test

PHP is a weakly typed language. Your statement:

$array['value'] = 'Test string';

is an implicit declaration (through assignment) of an associative array. So, a notice will not be generated.

However, if you were to write:

echo $array['value'];

before an assigment, then you'll receive an Undefined variable notice.
