Is there a function..

[Lamez]

Is there a string function that checks a string for numbers and symbols, or in other words, check to make sure it only contains letters, or do I have to write one?

Oh cool, so I would need to modify it like so:

 

if (ereg('[^A-Za-z]', $text)) {
  echo "Contains only letters";
}

 

Right?

ctype_alpha() See the manual as the ctype_ has many different applications, but there is a preg_match angle that you can do too which is something like this:-

 

!preg_match("/^\d+$/im", $input);<-- Inverting it so it does what you want, doesn't allow digits..

 

At least I think I have that right..

 

if (ereg('[^A-Za-z]', $text))

 

Ereg functions have been deprecated a while now in preference to preg_ functions... The manual tells you all you need to know..

I used ctype_alpha. I knew there was one, but I forgot it. Thanks!
