Obfuscating string values in PHP source code

Question

I want to protect PHP source code at easy way.

here is a example.

 $a = \"\\x46\\122\" . chr(578813952>>23) . \"\" . chr(0105) . \"\\x2d\"; 
 $b =          


        

Answer 1

ord will get you a character's ASCII value, using that we can generate the 3 things you want.

Type 1: Use dechex to convert int to hex.

$chr = 's';
$hex = dechex(ord($chr)); // 73

Type 2: Use decoct to convert into to octal.

$chr = 'E';
$oct = decoct(ord($chr)); // 105

Type 3: Use the << (shift left) operator.

$chr = 'e';
$bin = ord($chr)<<23; // 847249408
