PHP：警告 preg_replace

发布于 2024-12-12 12:20:31 字数 459 浏览 0 评论 0原文

自过去两天以来，我一直很难调试这个错误...在谷歌上搜索了每一个可能的解决方案但失败了...如果有人可以帮助我解决这个问题，那将非常有帮助：

Warning: preg_replace() [function.preg-replace]: Unknown modifier '$' in C:\xampp\htdocs\wi_class_files\autoMakeLinks.php on line 7

代码是：

class autoActiveLink {

    function makeActiveLink($originalString){

        $newString = preg_replace("[[:alpha:]]+://[^[:space:]]+[[:alnum:]/]i/","\\0", $originalString);
        return $newString;
    }

}

您忘记了分隔符（在掩码的开头和结尾）

class autoActiveLink {  
    function makeActiveLink($originalString) {  
        $newString = preg_replace("#[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]#i","<a href=\"\\0\" target=\"_blank\">\\0</a>", $originalString);
        return $newString;
     }
 }

You forgot your delimiters (at the beginning AND at the end of your mask)

class autoActiveLink {  
    function makeActiveLink($originalString) {  
        $newString = preg_replace("#[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]#i","<a href=\"\\0\" target=\"_blank\">\\0</a>", $originalString);
        return $newString;
     }
 }
