如何在PHP中延长编译时间
如何在PHP中延长编译时间
提问于 2014-10-04 18:36:30
我想知道如何编写一个需要更长的编译时间的脚本
我想在扩展工程中对进行测试。
稍后编辑:当PHP脚本加载时，代码被编译成字节码，这个字节码将由CPU解释。编译过程通常需要几毫秒，但我需要使这次测试PHP5.5中的OPCache扩展非常大。这个扩展应该缓存脚本字节码，这样它就不需要再次编译脚本了。

正如@PaulCrovella在评论中所说，我需要的是ApacheBench。
通过在包含大约600.000行代码的脚本上使用命令ab http://localhost/index.php，结果如下：
