php 去除注释,PHP 之去除代码中的注释

测试文件代码如下：

/**

* Created by PhpStorm.

* User: Yang

* Date: 2019/10/16

* Time: 10:25

// 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|.*)\n)|(#(\s*)?(.*))/", ‘‘, str_replace(array("\r\n", "\r"), "\n", $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";

preg_split("

注意：代码中有//的，都会去除
