i want to know if an obfuscated php script can be decoded and how.

YES!
99% of php obfuscators use eval() function to run the original code one page at a time.
To decode the obfuscated script, look for the eval() function on that same page and replace it with echo. it spews out the real code like a baby.

If u need an obfuscator, check d free obfuscator i have on my site http://www.afrisoft.org . its called phplocker and i'm presently creating a more secure version that will be available for free in a week.

@poster
aw r u? long tyme no visualisation!
dhtml told me he fixed my "email2database" script for you. Is it working fine now?

@ lojik
Thanks bro. i have being tryin 2 reach u, even thru ur website chatroom bt noway.yeh, dhtml fixed it. Please can u advise in what way can a script be obfuscated or coded dat will b prevent it 4rm being replicated. I have already done an obfuscation with a software n don't know if it can b broken, i think i still have ur email address, che make i send am to u make u test ur power?

sent it to ya mail n waitin.

What you sent is not really obfuscation. i have figured out your mysql username, password, host and database name without any decoding. What you did was just to change your variable names to very long names but no obfuscation was done on the real code.
You want real obfuscation? its plain gibberish that you'd see in your code. even you wont recognise your own code.

I just uploaded the updated version of my php obfuscator like 3 mins ago. download it and see real obfuscation in action: http://www.afrisoft.org/index.php/phplocker

hw can i stop a php code 4rm being decoded. which practise or program do u advise?

You cannot stop an obfuscated code from being decoded. Anything that can be Encoded can be Decoded.
What obfuscation does is just make it difficult and time consuming for someone to decode it.

Simple obfuscator gotten from StackOverFlow its CLI.

<?php
$infile=$_SERVER['argv'][1];
$outfile=$_SERVER['argv'][2];
if (!$infile || !$outfile) {
    die("Usage: php {$_SERVER['argv'][0]} <input file> <output file>\n";
}
echo "Processing $infile to $outfile\n";
$data="ob_end_clean();?>";
$data.=php_strip_whitespace($infile);
// compress data
$data=gzcompress($data,9);
// encode in base64
$data=base64_encode($data);
// generate output text
$out='<?ob_start();$a=\''.$data.'\';eval(gzuncompress(base64_decode($a)));$v=ob_get_contents();ob_end_clean();?>';
// write output text
file_put_contents($outfile,$out);
?>

how could it decode the php file encoded by turk mmcache
please fnd sample encoded file.
help me to decode it

Just passing by. However, there are some techniques that allows you PHP to be safe - if you run them as a service. Or you make an API
so that the main engine is kept hidden. EVen ioncube, zend and all those stuffs, i gat boys wey dey decode them easily.

If obfuscated, can't one just put it in code reformatter of some sort?

I don't see how that will help.

im a beginner , some guys decoded the turkmmcahe files easily in free lancer.
any experts tell how they do it,
any tutorial links are most welcome,
please help me
Thanks i advance

Please Decoded this. i obfuscated this raizlab software.. please help me.
