I'm posting a username and password from an input form and using them to check my arrays if they are there. If both are present, i want to echo a success message and if not i want to output an error message.
My success part of the if statement is working but my error message isn't outputting when i try. Can someone please help me.

I avise you to rewrite your code in this way:
$user_found = false;
for($x=0; $x<=10; $x++){
if($enteredusername == $userNames[$x] && $enteredpassword == $passwords[$x]) {
$user_found = true;
break;
}
}
if($user_found){
echo $successmessage;
}
else {
echo $errormessage;
}
Another way to achieve the same is to use in_array function:
if (in_array($enteredusername, $userNames)
&& in_array($enteredpassword, $passwords)) {
echo $successmessage;
} else {
echo $errormessage;
}
***
<?php
for($x=0; $x<=10; $x++)
{
if(($enteredusername == $userNames[$x]) && ($enteredpassword == $passwords[$x]))
{
$message = "success";
break;
}
else
{
$message = "failure";
}
}
echo $message;
?></div>

And note: <?php ?> tag was wrong in your code.
