[SOLVED] Is there a function that checks for non-numbers?

[Dogboys]

Like so if I was to enter "546s6" through a function or some script that it would return as something saying there is a letter or just something to signify that there is one.

 

Thanks.

is_numeric() to the rescue!

[Zane]

if(preg_match("/[a-zA-Z]/", "546s6"))
  echo "There's a letter";
else
  echo "There ain't one";

 

EDIT: is_numeric() may be quicker though

Thank you genericnumber1 as that will work just fine!

 

Thanks zanus, that'll also work!
