12 debugging tools for PHP developers (1)

PHP is a script language that develops rapidly and is most widely used in practice. It contains many features such as detailed documents, a large community, countless scripts available, and support frameworks. These features provided by PHP make it easier to use than scripting languages such as Python or Ruby.

To build innovative and fun Web applications, PHP developers are constantly searching for useful tools. In this article, I collected12 PHP debugging tools developed by developersThey help developers easily find and debug errors in applications and scripts. The following PHP debugging tool supports Ajax requests and contains a common data collector and a stack-based error processor. I hope you can see the convenience and usefulness of this list in future projects.
