Any buddy have php script to decode multi level base64_decode() and show proper php code.

What is your actual problem? echoing your code snippet looks like all you need. What is your actual question? — mickmackusa, Jun 15 '17 at 12:32

Note:

Encoded string will be decoded to exact string if the string encoded or decoded equal no. of times. It means two level encoded string can be decoded 2 level.

<?php
$string="Hello Stack Overflow";
echo $encodedString=base64_encode(base64_encode($string));//Multilevel(2) encode
echo base64_decode(base64_decode($encodedString));//Multilevel(2) decode

When I decode file there is two level encoded code. Please decode below code. if ($O0O00O00000OO = trim($_GET[base64_decode(base64_decode('WTJsMGVRPT0='))])) { eval(base64_decode(base64_decode('SkhSb2FYTXRQazh3TURBd1QwOHdNRTh3TURBZ1BTQjBjbWx0S0hOMVluTjBjaWdrVHpCUE1EQlBNREF3TURCUFR5d2dNQ3dnTWlrcE93PT0='))); eval(base64_decode(base64_decode('SkhSb2FYTXRQazlQTURBd01EQXdNRTh3TUU4Z1BTQjBjbWx0S0hOMVluTjBjbDl5WlhCc1lXTmxLQ1JQTUU4d01FOHdNREF3TUU5UExDQW5KeXdnTUN3Z01pa3BPdz09'))); } – Yuvraj Singh Shekhawat Mar 23 '17 at 07:43

I would recommend to create a function similar to this:

function multiBase64Decode($string, int $iteration = 1){
    for($i=0;$i<$iteration;$i++){
        $string = base64_decode($string);
    }
    return $string;
}
