    <p>Hey guys been hitting hard on google and stackoverflow on this one...</p> <p>I got php files encoded with php chr() function here is some of the code:</p> <pre><code> &lt;?php require_once chr(65).chr(100).chr(109).chr(105).chr(110).chr(67).chr(111).chr(110).chr(116).chr(114).chr(111).chr(108).chr(108).chr(101).chr(114).chr(46).chr(112).chr(104).chr(112);class WP_Amazonimportproducts_ImportController extends WP_Amazonimportproducts_AdminController{protected function _isAllowed(){return Mage::getSingleton(chr(97).chr(100).chr(109).chr(105).chr(110).chr(47).chr(115).chr(101).chr(115).chr(115).chr(105).chr(111).chr(110))-&gt;{"isAllowed"}(chr(99).chr(97).chr(116).chr(97).chr(108).chr(111).chr(103).chr(47).chr(97).chr(109).chr(97).chr(122).chr(111).chr(110).chr(105).chr(109).chr(112).chr(111).chr(114).chr(116).chr(112).chr(114).chr(111).chr(100).chr(117).chr(99).chr(116).chr(115).chr(47).chr(105).chr(109).chr(112).chr(111).chr(114).chr(116));}protected function _initImport(){$this-&gt;{"_title"}($this-&gt;{"__"}(chr(67).chr(97).chr(116).chr(97).chr(108).chr(111).chr(103)))-&gt;{"_title"}($this-&gt;{"__"}(chr(87).chr(80).chr(58).chr(32).chr(65).chr(109).chr(97).chr(122).chr(111).chr(110).chr(32).chr(73).chr(109).chr(112).chr(111).chr(114).chr(116)))-&gt;{"_title"}($this-&gt;{"__"}(chr(73).chr(109).chr(112).chr(111).chr(114).chr(116).chr(32).chr(80).chr(114).chr(111).chr(100).chr(117).chr(99).chr(116).chr(115)));return $this;}protected function _initProduct(){$   =Mage::getModel(chr(99).chr(97).chr(116).chr(97).chr(108).chr(111).chr(103).chr(47).chr(112).chr(114).chr(111).chr(100).chr(117).chr(99).chr(116));$    =Mage::getSingleton(chr(97).chr(100).chr(109).chr(105).chr(110).chr(47).chr(115).chr(101).chr(115).chr(115).chr(105).chr(111).chr(110))-&gt;{"getImportSettings"}();if (isset ($    [chr(105).chr(109).chr(112).chr(111).chr(114).chr(116).chr(95).chr(112).chr(97).chr(114).chr(97).chr(109).chr(115)][chr(99).chr(97).chr(116).chr(101).chr(103).chr(111).chr(114).chr(121).chr(95).chr(105).chr(100).chr(115)])){$   -&gt;{"setCategoryIds"}($    [chr(105).chr(109).chr(112).chr(111).chr(114).chr(116).chr(95).chr(112).chr(97).chr(114).chr(97).chr(109).chr(115)][chr(99).chr(97).chr(116).chr(101).chr(103).chr(111).chr(114).chr(121).chr(95).chr(105).chr(100).chr(115)]); </code></pre> <p>I have been trying to find a decoder as far I understand you can use ord() php function to decode it? I have found a script to encode text to chr(65) if it was possible to reverse it to make it decode php scripts encoded with chr(111).chr(65) it would be amazing I got few pages I need to decode and the only way I can think it will work if it can skip non chr(65) code so I can paste the whole page and decode it. What do you guys think? How can I decode it?</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;Convert String To PHP ASCII in PHP chr() function&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;b&gt;Convert String To PHP ASCII in PHP chr() function:&lt;/b&gt;&lt;br /&gt;&lt;br /&gt; &lt;form action="&lt;?php echo $_SERVER['PHP_SELF']; ?&gt;" method="get"&gt; &lt;textarea name="s" rows="20" cols="100"&gt;&lt;/textarea&gt; &lt;input type="submit"&gt; &lt;/form&gt; &lt;br /&gt; &lt;?php $string = stripslashes($_GET['s']); $chrstring = ""; for ($i=0; $i &lt; strlen($string); $i++) { $chrstring .= "chr(" . ord(substr($string,$i,1)) .
