What are the performance analysis tools for PHP functions?

PHP function profiling tools help identify bottlenecks and improve your code. This article introduces XHProf (sampling profiling), Tideways (commercial platform) and Blackfire.io (SaaS service); a practical case shows the use of XHProf to analyze function execution time.

Performance Analysis Tools for PHP Functions

Optimizing the performance of functions in PHP is crucial to improving the overall performance of your application. To help developers identify bottlenecks and improve their code, there are a variety of performance analysis tools available. This article will introduce some popular PHP function performance analysis tools and provide practical cases to demonstrate their usage.

xhprof

XHProf is a sampling profiling tool that provides data on function execution time by sampling stack traces as the function executes.

Usage:

// 安装 XHProf 扩展
pecl install xhprof

// 启用 XHProf
xhprof_enable();

// 执行待分析的代码

// 停止 XHProf 并获取结果
$xhprof_data = xhprof_disable();

$xhprof_runs = new XHProfRuns_Default();
$xhprof_runs->save_run($xhprof_data);

Tideways

Tideways is a commercial performance analysis platform that provides a wide range of performance analysis capabilities, including function-level analysis.

Usage:

Tideways requires a PHP extension and a cloud dashboard. See Tideways documentation for installation and usage instructions.

Blackfire.io

Blackfire.io is a SaaS-based performance analysis service that provides detailed performance data at the function level.

Usage:

Blackfire.io requires a PHP extension and an online dashboard. For installation and usage instructions, see the Blackfire.io documentation.

Practical case

The following is a practical case using XHProf:

xhprof_enable();

function heavy_function() {
    // 执行耗时的代码
}

heavy_function();

$xhprof_data = xhprof_disable();

$xhprof_runs = new XHProfRuns_Default();
$xhprof_runs->save_run($xhprof_data);

This example will generate an XHProf analysis report, which contains the execution of heavy_function time and other relevant information.
