I was trying to execute the user imput in $_GET["cmd"], but this doesn't work:
<?PHP
echo
$_GET["cmd"];
?>
Parse error: syntax error, unexpected '"', expecting T_STRING or T_VARIABLE or
T_NUM_STRING in /test.php on line 2
But I found other ways to make it work:
<?PHP
eval('echo '.$_GET["cmd"].';');
?>
<?PHP
$cmd = $_GET["cmd"];
echo $cmd;
?>
<?PHP
echo $_GET[123];
?>
I think second is the best way. Hope it helps somebody
