PHP 去除代码中的注释
测试文件代码如下：
<?php
/**
* Created by PhpStorm.
* User: Yang
* Date: 2019/10/16
* Time: 10:25
*/
// 计算和
// 计算和
// 计算和
$a = 1;
$b = 2;
$c = $a+$b; //总和
/*
* 求和函数
*/
function sum($a, $b) {
return $a + $b; //返回值
}
# 第二种注释
$a = 1;
$b = 2;
## 求乘积
$c = $a * $b; # 结果
//特殊
$usedFuncs = "abcd";
preg_split("//is", implode("", $usedFuncs), -1, PREG_SPLIT_NO_EMPTY);去除注释代码如下：
/**
* Created by PhpStorm.
* User: 25754
* Date: 2019/10/17
* Time: 9:54
*/
function removeComment($content)
{
return preg_replace("/(/*(s|.)*?*/)|(//.(s|.*))|(#(s*)?(.*))/", '', str_replace(array("
", "
"), "
", $content));
}
$content = file_get_contents("./test.php");
echo removeComment($content);结果代码如下：
$a = 1;
$b = 2;
$c = $a+$b;
function sum($a, $b) {
return $a + $b; }
$a = 1;
$b = 2;
$c = $a * $b;
$usedFuncs = "abcd";
