Character length

[newbtophp]

I've got alittle problem, the username is defined correctly via $_POST etc.

 

But can't get the character length to validate, it proceed without paying any notice. I want to username to be valid if its between 3->15 characters long (3 as minimum and 15 as maximum)

 

Heres my attempt using strlen():

 

elseif(!strlen($user) >= 3 && strlen($user) <= 15){

echo 'Username must be atleast 3 characters, and no longer than 15!';
}

 

I then tried doing it with regex:

 

elseif(!preg_match("/^\d{3,15}$/", $user)){

echo 'Username must be atleast 3 characters, and no longer than 15!';
}

 

:-\

if(!(strlen($user) >= 3 && strlen($user) <= 15)){
echo 'Username must be atleast 3 characters, and no longer than 15!';
}

//Slower RegEx
if(!preg_match("/^\w{3,15}$/", $user)){
echo 'Username must be atleast 3 characters, and no longer than 15!';
}
