PHP Form input validation

I need to know how to parse a String in PHP in my form.
For example when a use enters his/her name, I want to check that the user only entered alphabetical characters. How do I add check for char?:confused:

thanks

Most of the time numbers are not part of a name. But apostrophes, spaces, dashes, periods and commas might or can be.

PHP variable names must begin with "$" so this example may help, Try adding this to your form:for($i=0;$i<strlen($name);$i++)
{
if(($char[i]<'a' ||$char[i]>'z')&&($char[i]<'A' ||$char[i]>'Z'))
{
return FALSE;
}
return TRUE;
}With PHP you could also use a regular expression engine that would allow the above to be done without the loop.

thanks - it works fine, I just need to work on an error message to send back to user
