help me with PHP debugging.

[SH100]

I have error handling and everything set on the server. But don't know if I can debug php code one line of code at a time or by setting breakpoints at beginning of function or line of codes. This can be done with visualBasic but can it be done in php code?

I am working on e-commerce site: users login, users updating there personal information, searching and online payment. So I really think I should have some powerful debugger.

Please tell me is there any debugger like this and do I need to set it on server where php is installed or on my personal computer? I am FTPing to server which has php and my whole website.

Thank you.

You'll probably need one of the better PHP IDE's for such debugging tools, such as PHPDesigner, Zend Studio, etc.
