如何在我的开发服务器上启用通知 - 不工作

Question

I'm referring to How to enable notices on my development server

I expect the following code shall give me some warning, when I execute it through, as my $a is not explicitly declared as array

php a.php

<?php

ini_set('display_errors', 1);
error_reporting(E_NOTICE);

$a['key'] = 123;
echo $a['key'] . "
";   

However, no warning message being printed. Is there anything I had missed?

The PHP I'm using is PHP 5.5.3. I'm not sure this matters?

Wrong... by writing $a['key'] = 123; you declare an array and set the key key to the integer number 123. That's a valid PHP array initialization. (The PHP version does not matter in this case.)

To explicitely produce an error notice for testing purposes…

If you want to provoke an error notice for testing purposes, you could add this line:

count($ThisIsNotDefinedOnPurpose);    

which will produce an error notice saying

Notice: Undefined variable: ThisIsNotDefinedOnPurpose in … on line …
