PHP代码版本依赖 [英] PHP code version dependency

问题描述

在php的每个版本中，添加了一些新功能，并且某些功能被停止。

In each and every version of php, some new features are added and some features are stopped.

示例：

<?php
$hex = hex2bin("6578616d706c65206865782064617461");
var_dump($hex);
?>

将需要php 5.4.0及以上版本，因为hex2bin是在php 5.4.0中引入的。 >
在php.net中手动检查版本依赖关系，对于php代码中使用的每个内置函数来说都是乏味的。是否有任何自动/半自动的方式来确定执行任何给定PHP代码的php安装的最小版本（最大版本（如果适用））？

will need php 5.4.0 and above, as hex2bin was introduced in php 5.4.0.
It is tedious to check version dependency manually in php.net for each and every built-in functions used in php code. Is there any automated/semi-automated way to identify the minimum version (and maximum version if applicable) of php installation would be needed to execute any given php code?
