Checking proxy script

PHP script — By Script on September 18, 2009 at 12:43 pm

Finally, the last part of the post. Get ready for some “serious” programming.

Include whatismyip.php. Don’t forget to specify URL.
Copy getPage function to proxychecker.php or include it as a file.
Specify a time limit.
Write getProxies() function.
Write deleteProxy($proxy) function.
Specify badvars.php URL.
Specify sleep intervals.
Test and fix proxychecker.php. You don’t need to upload the script to a server. You can use your PC for testing.
Deploy the script. Don’t use the same host for badvars.php and proxychecker.php.
