Forgetting double equal-sign in php if-statement

问题

While coding, i sometimes make the error of writing a single = instead of == in an if-statement. So lets say i have this:

<?php
$name = 'piet';
if($name == 'jan'){
    print 'hello jan';
}

?>

And i make a mistake and write this instead:

<?php
$name = 'piet';
if($name = 'jan'){
    print 'hello jan';
}

?>

This won't throw an error of course, since it is valid php code. However, i never use this short-hand notation, so if i enter it by mistake it will break the logic of my code without telling me why. Is there a solution for this? I am using aptana which is an editor based on eclipse. Is there any way i can add my own custom errors to an editor (or php) based on for example regular expressions? Or are there any other approaches to alert me whenever i make this mistake?
