Alphabetic validation using php?

Friday, September 21st, 2007

We can validate a value for alphabets by the following function

function check_alphabets($str)
{
// Suresh written for validating alpha values
for($i=0;$i<strlen($str);$i++)
{
$chara=ord($str[$i]);
if(!((($chara>96) && ($chara<123))||(($chara>64) && ($chara<91))))
return 0;
}
return 1;
}

Here is the way to call the function

if(check_alphabets($_REQUEST[name])<1)$err=”Please enter alphabets” ;
