The following code will take the contents of the first row of a configuration table and create a constant for each attribute stored in it.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | // ----------------------------- LOAD CONFIGURATION DATA FROM DATABASE ----------------------------- // Each data element in first row is placed in a constant using attribute name as constant name // The array_slice function eliminates the first attribute in the row, 'id', which is the primary // key and not relevant for our purposes. $result = mysql_query("SELECT * FROM configuration WHERE id = '1'") or die(__LINE__." SELECT Error: ".mysql_error()); if($result != false and mysql_num_rows($result)) { foreach(array_slice(mysql_fetch_assoc($result), 1) as $key => $val) { if(!defined($key)) { define(strtoupper($key), $val); } else { user_error("'$key' already defined."); } } } // ---------------------------- /load configuration data from database ----------------------------- |
When automating a backup script, you may want to be able to create a folder named with the current date.
This quick line will accomplish that;

A glaring white background is common on websites, but a little subtlety in the background colour can make things a little easier on the eyes.

Pick what works for you, but a good example is #FDFDF0. Here's a sample. The difference is subtle, but effective;
| #FFFFFF PURE WHITE |
#FDFDF0 OFF WHITE |
