Development tools and debugging skills of PHP and CGI: Improve development efficiency

Abstract:
PHP and CGI are two commonly used Web development languages. In order to improve development efficiency, developers need to master some special development tools and debugging techniques. This article will introduce several commonly used PHP and CGI development tools, as well as some debugging techniques to help developers develop and debug more efficiently.

1. Development Tools

1. Sublime Text
   Sublime Text is a powerful text editor that supports syntax highlighting and plug-in extensions for PHP and CGI. It is fast, stable, and provides a wealth of shortcut keys and custom functions to facilitate developers to write and edit code.
2. PhpStorm
   PhpStorm is an integrated development environment (IDE) designed specifically for PHP development. It has a series of functions such as syntax checking, code completion, debugging, etc., which can speed up the PHP development process. Additionally, PhpStorm supports many popular frameworks and version control systems.
3. Eclipse
   Eclipse is an open source integrated development environment (IDE) that also supports the development of PHP and CGI. It has powerful code editing and debugging functions and is suitable for the development of large projects.

2. Debugging skills

1. Use var_dump() or print_r() function
   During the development process, we often need to view the value and structure of variables. PHP provides var_dump() and print_r() functions to help developers output detailed information about variables in the browser. For example:

$exampleArray = array('apple', 'banana', 'orange');
var_dump($exampleArray);

2. Set a custom error handler
   Sometimes, we want to capture PHP runtime errors and perform custom error handling. This can be achieved by setting a custom error handler. For example:

function customErrorHandler($errno, $errstr, $errfile, $errline) {
    echo "<b>Error:</b> [$errno] $errstr<br>";
    echo "在文件 $errfile 的第 $errline 行发生错误";
}

set_error_handler("customErrorHandler");

3. Debugging with Xdebug extension
   Xdebug is a powerful PHP debugger that can help developers set breakpoints in code, view the values ​​of variables, and Track the code execution process. It can be integrated with IDE to provide a more efficient debugging experience.
4. Using CGI debugging tools
   For the development and debugging of CGI programs, we can use some debugging tools specifically for CGI, such as Apache's mod_cgid module and CGIwrap tool. These tools can help us monitor the running status of CGI programs and output relevant debugging information.

Conclusion:
By mastering applicable development tools and debugging skills, developers can improve the efficiency of PHP and CGI development. Use the right development tools, such as Sublime Text, PhpStorm, and Eclipse, to speed up the code writing and editing process. At the same time, using debugging techniques, such as the var_dump() function, custom error handlers, Xdebug debugger, and CGI debugging tools, can help developers locate and solve problems faster. I hope the tools and techniques introduced in this article will be helpful to PHP and CGI developers.
