capitals

[squiblo]

I am making a register script and I am trying to give an error for passwords that are not recommended, such as "password" or the password being the same as the username. Something like this..

 

if ($newpass == "password")

 

But the problem with this is, the user might enter "paSSwOrd" and the condition will say they do not equal, so what can I do so the capitals the user inputs does not matter.

 

Sorry if you do not understand, I find it hard to explain.

 

Thanks

You can use strtolower to compare the passwords in lowercase, eg

if (strtolower($newpass) == "password") {
    echo $newpass . ' is not an acceptable password';
}

Also, maybe:

 

if(strcasecmp($newpass, 'password') == 0)

Although your question has been answered, here's a small tip:

 

To be more efficient, use single quotes in the password variable (e.g. strtolower($newpass) == 'password'). This will not make PHP search for special characters (such as \n) or variables in the string and thus use less memory.
