Cosi' risolvi:
#!/usr/bin/php5
<?
$fd = fopen("footer.php", "r");
$file = fread($fd, filesize("footer.php"));
fclose($fd);
$done=FALSE;
while(!$done) {
$fclean = str_replace("?><?", "", $file);
$fclean = str_replace("<?", "", $fclean);
$fclean = str_replace(" ","", $fclean);
if(substr($fclean, 0, 4) == 'eval') {
$fclean=str_replace("eval(", "print_r(", $file);
$fclean = str_replace("?><?", "", $fclean);
$fclean = str_replace("<?", "", $fclean);
$fclean = str_replace("?>", "", $fclean);
ob_start();
eval($fclean);
$file = ob_get_contents();
ob_end_clean();
} else {
print_r($fclean);
$done=TRUE;
}
}
?>
In pratica non fanno altro che fare il tutto innumerevoli volte, 42 per la precisione, bello schifo :)
