Question

我正在使用以下代码：

<?php
if(extension_loaded("IonCube Loader")) {     
  // Yes
}
else {
  // No
}
?>

我只是担心这会在启用IonCube的每台服务器上都无法运行。它似乎很标准，但我以前从未需要检查。这是检查的最佳方法，还是我应该使用更好的方法？

Answer 1

如果没有安装扩展程序，这将返回false，因此据我所知，这是检查扩展程序是否可用的正确方法。

另一种选择是使用get_loaded_extensions()。这将返回一个包含可用扩展名的数组。您可以检查此数组是否包含所需的扩展名。

Answer 2

另一种方法是

<?php
phpinfo()
?>

并在“附加模块”标题下查看，您应该可以看到

ionCube Loader

Answer 3

实际上我使用SSH来处理大部分事情，包括文件复制。当我需要检查ionCube加载器时，对我来说更简单的方法就是php -m。

由于字母顺序，Zend模块列在底部。

我的输出（最后2行）： [Zend Modules] the ionCube PHP Loader。

对于其他选项，我使用php -m | grep -v grep | grep MODULENAME。如果列出了它的加载，否则你将变空。（除非你忘记了grep -v grep管道。）

Answer 4

这里用最新编码器v9.0（PHP 5.6 / 7.0）加密的PHP代码，如果ionCube加载器工作，你应该看到文本“工作”，如果你看到php日志的空白页检查：

<?php //0046b
if(!extension_loaded('ionCube Loader')){$__oc=strtolower(substr(php_uname(),0,3));$__ln='ioncube_loader_'.$__oc.'_'.substr(phpversion(),0,3).(($__oc=='win')?'.dll':'.so');if(function_exists('dl')){@dl($__ln);}if(function_exists('_il_exec')){return _il_exec();}$__ln='/ioncube/'.$__ln;$__oid=$__id=realpath(ini_get('extension_dir'));$__here=dirname(__FILE__);if(strlen($__id)>1&&$__id[1]==':'){$__id=str_replace('\\','/',substr($__id,2));$__here=str_replace('\\','/',substr($__here,2));}$__rd=str_repeat('/..',substr_count($__id,'/')).$__here.'/';$__i=strlen($__rd);while($__i--){if($__rd[$__i]=='/'){$__lp=substr($__rd,0,$__i).$__ln;if(file_exists($__oid.$__lp)){$__ln=$__lp;break;}}}if(function_exists('dl')){@dl($__ln);}}else{die('The file '.__FILE__." is corrupted.\n");}if(function_exists('_il_exec')){return _il_exec();}echo('Site error: the file <b>'.__FILE__.'</b> requires the ionCube PHP Loader '.basename($__ln).' to be installed by the website operator.
