Image Grabber - Is this well written?

spadez · September 22, 2009

Hi,

I found this code online. I currently doesnt work but I think it probably just needs setting up / tweaking. Here is a link to the code online:

www.zombiemod.com/wip/wip/test2.php

Here is the code:

<?

/* IMAGE GRABBER SCRIPT */
/* By Dan Silvers 	*/
/* [email protected]		*/
/* version .02		*/

/*
This is really terrible looking code, but whatever.
It's still useful... email me bugs/crap/comments/etc.
*/


/***********************************/
/****	EDIT THESE THREE LINES 	****/
/***********************************/

/* YOU MUST HAVE TRAILING SLASHES OR THIS SCRIPT WILL MAKE FUNNY LINKS */

$DUMP = "/home/you/somewhere/yes";		// Full pathname to the directory to dump the images
					// CHMOD this directory 777 so we can write to it.

$URL  = "http://www.yourdomains.com";		// URL to wherever to dump the files

$TYPES = "jpg|gif|png|jpeg";			// File types to be allowed to grab. Separate by a pipe ('|'). 
					// Not case sensitive.

/********************************************************************************/


/* Timer class and functions */
/* I stole this from somewhere, but I forget where. */

class Timer {
    var $startTime,
        $endTime,
        $timeDifference;

    function start() {
        $this->startTime = $this->currentTime();
    }

    function finish() {
        $this->endTime = $this->currentTime();
    }

    function getTime() {
        $this->timeDifference = $this->endTime - $this->startTime;
        return round($this->timeDifference, 5);
    }

    function currentTime() {
        list($usec, $sec) = explode(' ',microtime());
        return ((float)$usec + (float)$sec);
    }

}

$timer = new Timer();
$timer->start();

My question is though. I aim to use this script to build upon. However, Id like to know if this script is well coded, because I dont want to start work on a bad base. If possible, could someone have a quick scan through the code and tell me if it is to a high standard or if I should look for another script online.

Thank you!
