Why not simply : "[a-zA-Z0-9]+" that would match any sequence of letters or
numbers ?

Asunto: [PHP-DB] problem with regular expression
i have a script to identify if the input is a combination of letters and
numbers
if (eregi("[a-zA-Z0-9][0-9]+[a-zA-Z][0-9a-zA-Z]",$fieldvalue))
print "alphanumeric"
} else {
not an alphanumeric
}
my problem is, when the string ends with a number, for example hello123, it
says "not an alpanumeric" ... it works fine when the number is placed before
the letters or in between letters ... why is that?
i would really appreciate your help, thanks very much
:)
