First, some of my web apps have multiple configuration files which are determined by the $_SERVER['HTTP_HOST'] value. If (stricmp( $_SERVER['HTTP_HOST'],’compiledweekly’) ) { // then I load compiledweekly config file }. So with that in mind, I had to add to the top of my cli scripts the following line:

$_SERVER['HTTP_HOST'] = ‘compiledweekly.com’;

This required me to have to edit the command line script every time i used it with another site. Here’s the trick: pass arguments to your command line so your script can parse them. Here’s how I did it to also include a verbose mode.

	if( count($argv) > 1 )
	{
		for( $x = 1; $x < count($argv); $x++ )
		{
			switch($argv[$x])
			{
				case '--verbose': { // Print results to std out
					$Verbose = true;
				}; break;
				case '--host': { // Print results to std out
					$_SERVER['HTTP_HOST'] = trim($argv[$x+1]);
				}; break;
			}
		}
	}

	if( $Verbose ) echo "Starting script...\n\n";
	// Continue with your script below

So with the following example I can run my script for my compiledweekly.com site with verbose information. Example:

/path/to/script.php --verbose --host compiledweekly.com

Now if you use your php script in a cron task, don't include the --verbose and make sure you check the $Verbose flag before printing any results. Don't forget to add to the end of the command line " > /dev/null 2>&1" minus the quotes, this sends any std out and std error messages to a black hole.

If your command line script is saved in a web accessible folder, here's a line you should add to the top so no web browser can execute your script:

if( php_sapi_name() != 'cli' ) die('Access denied.');

This will take your command line apps to a new level while giving you the ability to use existing web code. ]]> http://www.compiledweekly.com/2009/01/06/integrating-php-command-line-scripts-with-existing-web-projects/feed/ 0
