最近做一个问题,去除html中代码的JS脚本,代码如下

1 
      5      6     kkyz 
     
      m,dfd 7     
      10     
      11     ook12 EOF;13 14     echo "orginal text: \n\n" . $text . "\n\n";15     $pattern1 = "@
      
       (.*?)@is";    #等效于"@
       
        (.*)@isU"16     #末尾的i表示忽略大小写,s表示.可以匹配换行符,U与?等效,表示关闭无限匹配17     $pattern2 = "@
        
         (.*)@is";    #这是无限匹配的pattern,php默认就是无限匹配18     $text1 = preg_replace($pattern1, "", $text);19     $text2 = preg_replace($pattern2, "", $text);20     echo "text1: \n\n" . $text1 . "\n\n";21     echo "text2: \n\n" . $text2 . "\n\n";22 ?>
        
       
      
     

 

结果如下:
