PHPStorm's debugging tool: Make PHP code problems nowhere to hide

PHPStorm is a powerful integrated development environment that provides PHP developers with a series of powerful debugging tools. Through the debugging function of PHPStorm, developers can quickly locate and solve problems in PHP code, thus improving development efficiency. This article will introduce some practical debugging skills in PHPStorm to help you easily master various challenges in PHP development. Let PHP code problems have nowhere to hide and make development more efficient!

Breakpoints are one of the most commonly used debugging techniques. Setting it on a specified line in the code allows program execution to be paused for inspection and analysis at that line. In PHPStORM, you can do this by clicking in the margin or pressing Alt F9 (windows/linux) or Cmd F9 (MacOS) Set breakpoints.

<?php
$a = 1;
$b = 2;

// 设置断点
var_dump($a);

Use log output information

Log is an effective way to record events and information during program execution. PHPStorm provides convenient logging tools, allowing custom messages to be output when needed. You can use PhpStormPhpStormLoggerFactory to create a logger, and then use info(), warning(), error() and other methods to log messages.

$logger = PhpStorm LoggerFactory::getInstance("custom-logger");
$logger->info("Processing started");

View variable values

PHPStorm's variable inspector allows you to inspect the value of any variable in your code. This is useful for debugging complex blocks of code or identifying variable reference issues. To view a variable value, simply hover your cursor over the variable name or open the Variable Inspector window (Ctrl Shift V).

Execute code using evaluator

PHPStorm's evaluator feature allows executing code snippets or expressions without modifying the code. This helps test blocks of code on the fly or check specific conditions. To use the evaluator, open the evaluator window (Ctrl Alt E), enter the code, and press Enter to execute.

$result = 1 + 2;

Integrate third-party debugging tools

PHPStorm can be integrated with third-party debugging tools such as Xdebug and Zend Debugger. This provides additional debugging capabilities such as remote debugging, stack trace analysis, and performance profiling. To enable third-party integration, go to Preferences > Languages ​​& Frameworks > PHP > Debugging.

Summarize

PHPStorm provides a wealth of debugging tools that can help PHP developers quickly identify and solve code problems. From breakpoints to logging, variable inspectors, and evaluators, these tools provide a comprehensive and efficient debugging experience. Proficiency in these tools can significantly improve development efficiency and ensure code quality and reliability.
