Changing your WordPress Database Table Prefix

An article at BlogSecurity.net points us to a plug-in that will change the table-prefix of the MySQL database tables used by your blog.

This step contributes to the security of your blog by letting you swap the default (and thus obvious) 'wp_' table prefix for something obscure that a hacker could not guess at.

Remember that if your WP installation does not have error reporting turned off an attacker may yet be able to force your installation to reveal critical information by forcing an error and reading sensitive database information from the error messages.

Capturing the filename from a path in PHP

When you want to isolate the base filename from a path string, this is the way to do it:

[sourcecode language='php']
$path = "/home/project/folder/mypage.php";
$file = basename($path);          // $file is "mypage.php"
$file = basename($path, ".php");      // $file is "mypage"
[/sourcecode]

See dirname() and pathinfo() for related information.
