An Intro to using Ajax in PHP
admin — Sun, 27/08/2006 - 9:16pm
AJAX is an acronym for Asynchronous JavaScript and XML. Simply put, AJAX can be read "empowered JavaScript", because it essentially offers a technique for client-side JavaScript to make background server calls and retrieve additional data as needed, updating certain portions of the page without causing full page reloads.

Column types and attributes
1) Be familiar with MySQL's column types along with their ranges/lengths. You should use the smallest column type that will hold the data that you expect to store. Most of the time, you probably don't need INT, because MEDIUMINT, SMALLINT, or TINYINT have enough range. Using a smaller type saves space and speeds things up.

Common Tips

PHP tags
I recommend always using the full PHP open tag, <?php, rather than the short one, <?. This means also that instead of <?=$var?>, it's better to use the full <?php echo $var?>. Using the full open tag ensures that your code will work on all PHP installations, regardless of the short_open_tag setting.

Escaping Techniques

magic_quotes, addslashes(), and stripslashes()
magic_quotes_gpc, when on, automatically adds slashes to all GET/POST/COOKIE data so that you don't need to use addslashes() before using GET/POST/COOKIE data in MySQL queries, etc. (e.g. with magic_quotes_gpc OR addslashes(), I'm becomes I\\'m). Well, magic_quotes_gpc is no convenience and just complicates things!
