Scanning PHP Scripts

[nEw_boY]

Today I was helping 2 of my friends.

1. eFriend who got his site hacked and
2. College friend who was working on outdated script, kinda large project though he is just beginner.

I was wondering if there is any way you can check PHP scripts for possible call back to external IPs ?
Something like nulling script but rather than that, I`m actually helping them to clean the scripts so that they wont ping dead server in old script or hacker's stuff.

Is there anyway to do that ? Can any nuller help me, I just want to clean them, not pirate them in anyway. There is a lot of custom/private code included so we cant just go over fresh installation.

Use ultraedit. It can search file contents in folders and subfolders using standard or regexp . It will list results in a box and if it is something you want to check than just click that line and it will oprn the file on that line.

Search for href or html or regexp links.

If you are coding in Windows, you can execute the code using the PHP executable and monitor the connections using Wireshark.
