How to use EasyEclipse for PHP debugging

EasyEclipse is a flexible and easy-to-use tool based on the Eclipse platform. It supports development needs in many different fields. For developers who use EasyEclipse for PHP development, debugging is a very important part of the work. Therefore, this article will introduce how to use EasyEclipse for PHP debugging, hoping to be helpful to PHP developers.

1. Preparation

Before using EasyEclipse for PHP debugging, we need to ensure that PHP and XDebug have been installed on our machine. Among them, XDebug is an essential extension for PHP debugging. It allows us to set breakpoints and track the code execution process. It also supports remote debugging. Therefore, in order to use EasyEclipse for PHP debugging, we must first configure XDebug.

The process of installing XDebug will not be introduced in detail here. Readers can refer to the official XDebug documentation for installation and configuration. It should be noted that we need to add the following content to the php.ini file to enable XDebug.

[xdebug]
zend_extension=xdebug.so
xdebug.remote_enable=on
xdebug.remote_host=localhost
xdebug.remote_port=9000

If we already have this configuration, then we can start configuring EasyEclipse and debugging PHP.

2. Start debugging in EasyEclipse

1. Configure project

The majority of PHP developers should be very familiar with how to create PHP projects in EasyEclipse. No more expansion here. We have a PHP project by default, and now we need to debug and configure our project.

Open the project properties window, select the "PHP Debug" tab, and check "Enable project specific settings":

Then you can further configure:

• Debug mode: Select "Debug as PHP Web Page" or "Debug as PHP Script", Default Concentration.
• URL: Configure the URL of the request entry file.
• Browser: Select a browser to simulate user operations.

These configuration items are very important and need to be adjusted according to your actual project conditions.

2. Start debugging

On the toolbar of EasyEclipse, click the "Debug" button.

Select "Debug Configurations", select "PHP Web Page" or "PHP Script" in the pop-up window, and then click the "New launch configuration" button.

On the general options page, we can configure the operations when the project is started: open browser, open window, background execution, etc. Since readers have different needs here, just stick to the default settings first.

In the PHP export device and XDebug options page, we need to make some necessary configurations:

• In the "PHP export device" page, select your PHP version and select The project requires further configuration.
• In the "XDebug" page, check "Enable XDebug", and then configure the IP address, port number, document root directory and other information of the "PHP server" according to the actual situation.

3. Start debugging

After setting the above configuration, we can start debugging! Click the "Debug" button to enter debug mode.

First, EasyEclipse will open the entry file we set in the browser. At this time, our page has entered debugging mode. There will be a "Variables" window on the right side of the page, which will display the current All variables of the page and their values. We can use this window to check the values ​​of variables to help us find problems.

When the code encounters a breakpoint, the program will pause execution. At this time, we can check the value of the variable, execute code and other operations through the "Variables" window. If you need to continue executing the program, you can click the "Resume" button in the upper left corner.

In addition to debugging by setting breakpoints, we can also use functions such as "trigger_error()" or "xdebug_var_dump()" in PHP code to print out the value of variables to further help us debug.

3. Conclusion

This article introduces in detail how to use EasyEclipse for PHP debugging, including the installation and configuration of XDebug, the implementation of debugging operations, etc. I hope it will be helpful to readers. Debugging is a key link in the development process. Improving our debugging capabilities can help us find problems faster, solve problems faster, and improve our development efficiency.
