Re: [PHP] Regular Expression
oops. The expression should read '/\[([^\]]+)\]/'
Thanks all, i used this code and it works:
preg_match("/\[(.+)\]/",$msg_array[$i],$segments);
$title = trim($segments[1]);
$description = ereg_replace("\[ $title \]", "", $msg_array[$i]);
Does anyone know a good regex tutorial? I'll probably bump into it again.
Regex'es seem to be very usefull.

Re: [PHP] Regular Expression Help
I want to delete everything after a tab (or space) on each line of
a text file and can't figure it out.
An example line is
ARIA 5.19 -0.0625 -1.19 5.25 4.5 48.5 100300
you can explode on a tab $arrlines = explode("\t", $the_line);
then save $arrlines[0] from every line.
Don't know if it's the most optimal way but it works :)

Re: [PHP] Regular expression problems
From: "Dan Watt" [EMAIL PROTECTED]
Im trying to build a user login system, and when there is a new user, I
need
to validate that they are usign using word characters ([0-9A-Za-z_] or
\w)... I have TRIED MANY different regular expressions to test this, but
none work. This seems so simple but I am missing something. I need a
expression that returs true ONLY if ALL the characters match \w Any
help would be appreciated.
?php
$username = "johnny";
if (!eregi("[^A-Z0-9_-]", $username))
{
echo "username OK";
}
else
{
echo "bad username!";
}
?
Assuming you only want letters, numbers, underscores or hyphens. If you
really want \w you would need to use preg instead of ereg, and then you need
PCRE support in PHP. Or you could use ereg's character classes, I think the
pattern would look like: "[^[:alphanum:]]". However you are probably better
off using an explicit set of characters as I have shown, so that it is
obvious what is and is not allowed.

ok, that was my problem Was using ereg... All the places I read about
how to do regular expressions (book, online...) did NOT clarify that \w and
such would need preg.. Thanks!

The ? meta-character is used for matching zero or one occurence of the
preceding character , in this case , l .
T'his means that you'll match all words that begin with 'Wi' and continue
with one or zero 'l' .
More than that, it'll match any string in which a capital 'W' is followed
by a lowercase 'i'. For example:
"Don't you love Wile E. Coyote?"
"I'm Wigging Out."
"The password is 'KiWi'."
"The password is '123Wiked'."

Re: [PHP] REGULAR EXPRESSION
I 'd like to have an input that contains only a to Z and space and
- nothing else like numbers or whatever and also does not
start
with space !
till now with ur help i get the following :
(!ereg("[a-zA-Z[:space:]-]", $name))
All those weird characters you typed are not ASCII, and are not valid to
just throw into a string like that.
You can maybe use Regex hex representations of them, but they aren't going
to be the same characters on many people's browsers anyway...

since the pattern has an 'or' (|), you have to look in either the second
or the third element of the array you use to store values from the ereg.
Jeff
can anyone help me figure out a regular expression to find the value of
a tag element?
for example:
tag element="my value"
tag element=value
tag element="my value" nextelement
tag element=value nextelement
tag element = "my value"
tag element = value
tag element = "my value" nextelement
tag element = value nextelement
so in each of the above i need to find either "my value" or "value"...
i tried this but it wont work for every situation:
ereg("element[ ]*[=][ ]*[\"]?([^\"]*)[ |\"|].*" ...
thanks for your help - regular expressions are not my best area!
jamie.
