This article mainly introduces the method of debugging code with Xdebug in phpstorm, which is very detailed and has certain reference value. Friends who are interested must finish reading it.

Students who have used Java, C# and other static languages to debug the code often make a breakpoint, and then easily debug, while PHPer debugging code is often echo $a world exit; very inconvenient, some students sometimes do not delete the breakpoint to commit, which causes a lot of trouble, is there any way to debug more elegantly? Of course there is. Here is a PHP module xdebug,xdebug installation tutorial. Using it for PHP code debugging can effectively reduce the workload and BUG debugging time, especially in some complex programs, you can't find the problem just by looking at it.

Xdebug is an open source PHP program debugger (that is, a Debug tool) that can be used to track, debug and analyze the health of PHP programs.

If it is an integrated environment, such as phpstudy, you don't need to install it yourself, just go to the environment-> PHP- > set (don't get mixed up with the PHP version number)

Set the lower port number here, as long as you like. I set 9001.

Check the phpinfo and search for the xdebug module.

Next, open the phpstorm,ctrl+alt+s to open the settings and go to the debug settings, and change the port to the port number you set earlier (other default is OK, of course, you can also open it, if you can't read English, you can translate it)

Click Servers and click + to create a new one. The name is arbitrary. Host fill in the domain name you want to Debug (such as localhost, I filled in a virtual domain name here). The port number defaults to 80.

Then there is an Edit Configurations in the upper right corner. Click Open.

Click the plus sign to add a PHP Web Page

Name is optional. Server chooses the one you configured just now. StartUrl is the address of the interface that starts. If I want to debug an interface that places an order, I fill it in and click on the Validate pointed to by the arrow.

The first option is to debug locally and the second is to debug remotely. I won't talk about remote here, so as not to confuse your first input box to fill in your own project directory, because mine is the tinkphp framework. I pointed it to the public directory of the project directory and filled in my domain name. Here the editor automatically helps to fill in the domain name.

Click the Validate button, and phpstorm will help check whether the configuration is correct. If there is any mistake, please follow the prompts to modify it.

Finally, click on the bug in the upper right corner, and it will automatically open the browser for debugging. If the phone next to the bug turns green, it is listening to port 9001.

At this time, phpstorm will automatically open the debug console, click the arrow to automatically take the next step, and click the red dot on the left to break the point.

What if you want to use postman?

Bring this parameter over here.

Add this pair of key-vlue to the parameters of postman, and click send to automatically turn on debugging (postman will be sent until the breakpoint debugging is completed)

The tutorial I wrote hopes to enable readers to run xdebug with the shortest steps, but some details are ignored. Interested students can go online to find more detailed configuration and instructions (of course not) debug console simple instructions.

You can break the point on the left and stop when the code executes to the breakpoint.

When this button is clicked, a line of code will be executed, but the entire function will be executed directly when a function is encountered.

This button also executes a line of code, which can be executed inside the function.

Skip to the next breakpoint

The first page can see all the variables clearly.

The second page can print variables and even execute object function methods (useful)

The third page is to view the output

Problem summary

During breakpoint debugging, Apache disconnects automatically after the PHP script times out and returns a 500th error.

Add to the http.conf file of apache
