Any ideas for simple, always useful PHP functions?

Asked by Vincentt (8043points) November 17th, 2007

Hi, I’m looking for a few small PHP functions to write that might come in handy. It wouldn’t really matter if they already exist somewhere, I just need to practise this new technique but can’t think of any useful functions. Thanks in advance.

A regular expression to check if an e-mail address is valid. Tons of examples out there but it gets your hands dirty with a few necessary techniques.

there is always the login and logout. making them into function would come handy and easy to use. Sorry I am blank too :S

This isn’t too useful but it can save a little typing

function isPost() {
return $_SERVER[‘REQUEST_METHOD’] == ‘POST’;
}

if (isPost()) {
/* do form stuff */
}
