I have a real problem that I can't seem to figure out.
I need an ereg pattern to search for a certain string
(below). All this is being shelled to a Unix grep
command because I'm looking this up in very many

I've made myself a <INPUT TYPE="HIDDEN" tag> that
contains in the value attribute a list of
comma-delimited numbers. I need to find if a certain
number is in these tags (and each file contains one
tag). I need an ereg statement that will let me search
these lines to see if a number exists, obviously in
the beginning or the end or the middle or if it's the
only number in the list. Here's what I mean (searching
for number 1):

"1,2,3,4,5">   //beginning

"0,1,2,3,4,5">   //middle

"5,4,3,2,1">   //end

<INPUT TYPE = "HIDDEN" NAME = "numbers" VALUE = "1">  

This is frustrating me, because each solution I come
up with doesn't work. Here is my grep/ereg statement
so far:

$commanumberbeginning = "[[0-9]+,]*"; //this allows 0
or more numbers before it, and if there are any, they
must have 1 or more digits followed by a comma

$commanumberend = "[,[0-9]+]*"; // this allows 0 or
more numbers after it, and if there are any, they must
have a comma followed by 1 or more digits

$ereg-statement=$commanumberbeginning .
$numbertosearchfor . $commanumberbeginning;
//$numbertosearchfor will be obtained through a select
control in a form

grep '<INPUT TYPE = "HIDDEN" NAME = "numbers" VALUE =
"$ereg-statement">' *.html

This problem is kicking my butt. Any help?
