For some reason, when I type in Mon, Tue
It gives me this:

You need a leading slash as a delimiter, eg
/Sat/i
also note that you will match any phrase that contains 'sun', 'mon' etc, which
can also have irrelevant text, eg 'Mars Jupiter Saturn' will match, but thats
probably not what you want

You're lacking the starting delimiter '/'

$result = mysql_query (select indexNo,Reply from Acknowledgement order
by indexNo) or die (Invalid query);
while ( $rset= mysql_fetch_array($result)) {
/* Lets check the reply with the database*/

Re: [PHP] preg match
I'm not sure what you're trying to do with preg_match, since the
parameters you send to it, are from the database, and an undeclared
variable $msg(which is what exactly). Unless you give us examples of
the arguments to preg_match, and what you expect the results should
be, as well as what they are, we can't really be of much help.
Having that said:
You are using /$chk_msg/ as the first parameter. since you are
simply putting /'s around $chk_msg, this leads me to suggest that you
don't need regex at all, and perhaps would be better using some of the
string functions. strpos() ( http://www.php.net/strpos ) springs to
mind.
Just a few tips:
As an aside, I notice that you are connecting to localhost:3306. Just
incase you didn't know, when you connect to localhost through
mysql_connect, assuming you are on a unix host, it uses a unix socket,
regardless if you specify a port. If you want to override this
behavour, and use TCP sockets, you can connect to 127.0.0.1.

[PHP] preg match compilation error
I found a reqular expresion that I'm using to check for valid characters in
file names.
Here's the sample code:
if(preg_match([^a-zA-Z0-9,._\+\()\-],$filename))
{
//blah, blah, blah
}
However, when I run the script I get the following error:
Warning: Compilation failed: unmatched parentheses at offset 17 in
/home/httpd/sigmarapid/html/test/upload.php on line 137 (the line with the
preg_match)
I'm new to regular expressions so any help would be greatly appreciated.

preg_* need a pattern deliminater (most commonly /,#, or !) so it should be:
preg_match(/[^a-zA-Z0-9,._\+\()\-]/,$filename)
Now you can get rid of all the escapes because mosts characters loose
their special meaning inside a character class:
preg_match(/[^a-zA-Z0-9,._+()-]/,$filename)
You can get away without escaping the '-' because it *can't* be
considered a range of characters since it is last (or if its
first).
That should work.

Re: [PHP] preg match compilation error
Do you realy want to use [ and ] as patern delimiters? My quess is that
you want to use it for defining character class. Then the only character
that must be escaped is -
'/[^a-z0-9,._+()\-]/i'

It has the exception of being the range character if it is either the first or last character in the class.

[PHP] preg match question
I am passing a string and making sure all the characters in that string
are valid.
Example:
For a persons age I am using:
if (!preg_match(/^[0-9]+$/, $Age)) echo Enter numeric value for age.
But how would I include the following characters as permissible in preg
match
~!@#$%^*()-=_+,.?/\|{}[]
since some of these characters have special meaning in PCRE regrex syntax??
