What's the best and worst thing about PHP?

Someone should create a PHP library that shortens function names:

file_get_contents could go to fgc
file_put_contents could go to fpc
mysql_connect could go to mc
mysql_real_escape_string could disappear completely
file_exists -> fe
get_html_translation_table should be ghtt or something similar
etc.

PDO vs. MySQLi

Does anyone have any experience with which is better for working with databases in PHP? I personally use PDO whenever possible, but I'd like to hear what other people prefer and why.

Let me know!

I've seen a lot of PHP programmers use the following syntax for checking if multiple variables are set with the isset() function.

if( isset( $_POST["fname"] ) AND isset( $lname ) )
//Do Something

However, the isset() function can take multiple parameters and will only return TRUE if all are set and not equal to NULL. The above code could be simplified to:

if( isset( $_POST["fname"], $lname ) )
//Do Something

I hope that this helps someone out there!

Here's an awesome PHP trick that I learned recently that has saved me a lot of time!

Usually, when working with form data, one has to test to see if a POST (or GET) variable has been set before testing to see if it is equal to some value or otherwise using it in a program.

Example:

if( isset($_POST["fname"]) && ( $fname = $_POST["fname"] ) == "John" )
//Do Stuff with $fname

Isn't that terribly long? The truth is that you can do it much more easily by:


if( ( $fname = &$_POST["fname" ]) == "John" )
//Do Stuff with $fname

This trick has saved me a lot of typing, and if the POST variable doesn't exist, $fname will have a value of NULL.

The reason that you need the '&' is because PHP gives nasty error messages if it can't find an array element, and asking for the reference of a non-existent element returns NULL without errors.
