[Tutorial] Writing unreadable php scripts (Tips & Tricks)

1. Always write your 'obfuscated' scripts in one line. That way it really fucks with your eyes if there are like loops and shit.

2. PHP variable names can be ANY character. That means they can be retarded chinese characters, or invisible characters. For example, this works:

PHP Code 

<?php $‌="I'm gay."; echo($‌); ?>

3. You can select from arrays in several ways. array[0] is the same as array[0x0]. It just needs to be an integer in the end.
For example, these scripts all work:

Hex encoding:

PHP Code 

<?php $x=["I'm","gay."]; echo($x[0x0]); ?>

XOR encoding:

PHP Code 

<?php $x=["I'm","gay."]; echo($x[(("."^"`")^"~")]); ?>

Equations:

PHP Code 

<?php $x=["I'm","gay."]; echo($x[6*9-54]); ?>

Other vars:

PHP Code 

<?php $x=["I'm","gay."]; $z=5*5; echo($x[$z-25]); ?>

There are a lot of ways to do this, so feel free to experiment. Nothing is impossible in php lol.

4. Numbers.
You can change numbers to their negative value just by using NOT, or !

PHP Code 

<?php $x=!0; echo($x); ?>

//Echos out 1
You can use hex instead of integers as we already said above.

PHP Code 

<?php $x=0x69; echo($x); ?>

//Echos out 105 lol.

5. Double dollar signs. You can use double dollar signs, which is stupid, but still possible. You just have to silence the errors using @.

PHP Code 

<?php @$$S="I'm gay."; echo(@$$S); ?>

There are a lot more ways to make your php scripts as messy as possible.
Just experiment.
