PHP已成为时下最热门的编程语言之一,然而却有许多PHP程序员苦恼找不到合适的工具来帮助自己分析和解析PHP代码。今天小编就为大家介绍几个非常不错的工具,来帮助程序员们提高自己的工作效率,一起来看看吧!

PHP Parser

PHP-Parser是一个用PHP编写的PHP解析器(支持PHP 5.4以及更早的版本),这种特殊的解析器非常适合静态代码分析。该工具的目的就是简化静态代码分析和操作,它使程序员能够以编程的方式来处理任何应用程序的代码。 

PHPSandbox

PHPSandbox将运行PHP作为独立进程的一种方式。 它为程序员提供一种外围脚本的保护,比如错误、崩溃、运行慢的脚本,或者不适合在代码中运行的脚本,都可作为独立进程来运行。

PHP Mess Detector

PHPMD这个工具能够探测PHP源代码中一些潜在的问题。例如:

  • 可能存在的Bug
  • 未达最佳标准的代码
  • 过于复杂的语法
  • 从未使用过的参数、方法、属性

PHPCPD

PHPCPD是一个在代码中寻找类似模式的工具,使用它是为了在代码库中识别代码在何处被复制或粘贴。这是常规构建过程中一个非常有用的工具,它会帮助程序员分析代码,以避免在代码库中重复调用函数。

PHPCheckstyle

PHPCheckstyle是一个帮助PHP程序员检查代码和报告错误的工具,运行于PHP 5.0以及更高的版本。通过SVN钩子脚本的方式来调用PHPCheckstyle,可以强制代码必须符合预先设定的编码标准(比如PEAR编码标准),有助于在多人合作项目中提高代码整体质量。

Ubench

Ubench是一个用于评测PHP代码执行时间和内存使用效率的开发库。使用方法如下:

<ol class="dp-j">
<li class="alt"><span><span>require_once </span><span class="string">'src/Ubench.<span><a><span>php</span></a></span>'</span><span>; </span></span></li>

<li><span> </span></li>
<li class="alt"><span>echo $bench->getMemoryPeak(<span class="keyword">true</span><span>); </span><span class="comment">// memory <span><a><span>peak</span></a></span> in bytes</span><span> </span></span></li>
<li><span> </span></li>

<li><span> </span></li>
<li class="alt"><span>echo $bench->getMemoryUsage(); <span class="comment">// 152B or 90.00Kb or 15.23Mb</span><span> <br></span></span></li>
</ol>
