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
:)
