Help,
This is driving me mad and I know there must be a very simple solution. I’m
trying to detect if my strings contain ONLY certain values. For instance, I’
m trying to limit my “$name” string to just a-z (case insensitive)
characters. I’m trying to do this with preg_match (unless there is an easier
way). However, I’m failing badly. This is what I have so far:
if (preg_match ("/[a-z]/i", $name))
{
echo "string only contains characters ranging between a to z";
}
else
{
echo "string contains characters outside of the a to z range";
}
This checks for the occurrence of any a-z characters in the string. However,
want I require is for it to allow JUST those characters. At the moment if
$name = “abc1” then True is returned (I want False returned here because of
the “1”). I don’t know how to write this functionality in preg_match format
:-(
Please help
Thanks
James
