调用未定义的函数dl() [英] Call to undefined function dl()

问题描述

我正在使用PHTML编码器来编码我的php文件，但是当我运行编码文件时，它给出了错误消息调用未定义的函数dl()". 有人请帮忙.

I am using PHTML encoder to encode my php file but it is giving error "Call to undefined function dl()" when i run the encoded file. Somebody please help.

<?php
    if(!function_exists("phtmldec")){
        $w=(substr(PHP_OS,0,3)=="WIN")?1:0;$ln="phtmlenc".phpversion();$cd=dirname(__FILE__);

        if($w){
            $ln=$ln.".dll";if($cd[1]==":") $cd=substr($cd,2);
        } else {
            $ln=$ln.".so";if(strlen($cd)<3) $cd=getcwd();
        }

        if(version_compare(phpversion(),"5.2.5")==-1){
            $cd1=ini_get('extension_dir');
            $cd2=PHP_EXTENSION_DIR;

            if($cd[strlen($cd)-1]!="/")$cd=$cd."/";

            if($cd1[strlen($cd1)-1]!="/")$cd1=$cd1."/";

            if($cd2[strlen($cd2)-1]!="/")$cd2=$cd2."/";

            if($cd1[1]==":") $cd1=substr($cd1,2);

            if($cd2[1]==":") $cd2=substr($cd2,2);

            $ic=substr_count($cd,"\\")+substr_count($cd,"/");
            $ic1=substr_count($cd1,"\\")+substr_count($cd1,"/");
            $ic2=substr_count($cd2,"\\")+substr_count($cd2,"/");
            $en=str_repeat("../",max($ic,$ic1,$ic2))."..".$cd.$ln;
        } else {
            $en=$ln;$r=dl($en);if(!$r)exit("Unable to load $en");
        }

        $p="F4\$A016YC2@Y(8Q[Y!2F3[@K2.0>K0Z%5^#2\\,&;5L7\$<KHL)BH<`";
        phtmldec($p);
    }
?>

推荐答案

@ k102提到的dl()从5.3开始默认被禁用:

as @k102 mentioned dl() has been disabled by default since 5.3:

如php文档中所述: http://php.net/manual/en/function.dl.php

as refered on the php documentation: http://php.net/manual/en/function.dl.php

    5.3.0   dl() is now disabled in some SAPIs due to stability issues.
The only SAPIs that allow dl() are CLI and Embed. Use the Extension Loading Directives instead.

根据此处的建议，改用扩展加载指令: http://www.php.net/manual/en/ini .core.php#ini.extension

as suggested there, use the Extension Loading Directives instead: http://www.php.net/manual/en/ini.core.php#ini.extension

基本上，您唯一的选择是:

Basically your only choices are:

1. 在php.ini上加载正确配置的扩展名
2. 使用文档中提到的仍支持dl()的上述SAPI之一: (CLI，CGI和嵌入)
3. 如果确实需要动态加载php版本，请降级

1. Load the extension configuring it properly on the php.ini
2. Use one of the mentioned SAPI's that still supports dl() as mentioned in the documentation: (CLI, CGI and Embed)
3. Downgrade your php version if you really need to load it dinamically
