Best method for checking if IonCube Loader is installed

Question

I'm using the following code:

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

I'm just concerned that this won't work across every server with IonCube enabled. It seems pretty standard, but I've never needed to check before. Is this the best way to check, or is there a better method I should be using?

I am sorry, but is there a point to this? If you try to run an IonCube script on a server where it isn't loaded, that won't work and you'll get an error message. – Imposing

Yeah, there's a point. I'm running a script to download an encoded script from a server and run it. If IonCube isn't enabled, the whole app will fail. Checking for IonCube saves me a server request and prevents the error message you are referring to. – Borghese

For me it's also easier to check for it than digg on the logs because a blank screen... – Lindholm

Answer 1

If the extension is not installed this will return you false, so as far as I know it is the correct way to check if an extension is available to use.

Another option is to use get_loaded_extensions(). This returns you an array with available extension names. You could check if this arrays contains your desired extension.

Verse

$gefunden = false; foreach ( get_loaded_extensions() as $number => $extension_name ) { if ( (strpos( strtolower($extension_name) , "ioncube" )) === false) { // do nothing } else { $gefunden = true; } } – Whitver

Answer 2

Actually i use SSH for the most of the things, including file copy. When i need to check for ionCube loader the easier way for me it's just php -m.

Zend modules are listed on the bottom, due to the alphabetical order.

My output (last 2 lines): [Zend Modules] the ionCube PHP Loader.

For other options i used php -m | grep -v grep | grep MODULENAME. If it's loaded is listed, otherwise you will get empty. (except if you forgot the grep -v grep pipe).

As the ionCube Loader is foremost a PHP engine extension, you can also use php -v and grep there. – Ankney

Here the PHP code encrypted with latest encoder v9.0(PHP 5.6/7.0), if ionCube loader is working you should see text "working", if you see blank page check for php logs:

<?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.
