Deobfuscation of php code. Is it possible to?

Question

PHP

Good afternoon. I came across this code:
Is it possible to parse such a code?
If so, are there any services?

Answer 1

Can't decode HEX strings in a file?

<?php   file_put_contents(pathinfo($argv[1], PATHINFO_FILENAME).".out", preg_replace_callback("/\\\\x([0-9a-f]{2})/i", function ($a){return pack("H*" , $a[1]);}, file_get_contents($argv[1])));   ?>

Save to dehex.php file and run with command php -f dehex.php file_with_hex.txt.
What do you need to replace the line file_with_hex.txt with - guess?
And guess what is now in the appeared file file_with_hex.out ?

Answer 2

Up to this type, you can automatically:
$GLOBALS["lhonmhqjabnfbcovnnbvdicefanx"] = "_F";
Well, then with your hands.

Answer 3

No. Code as code, quite valid and working. Look at what operations are performed there, what functions are called, with what parameters.
