Need help with a regular expression

Need help with a regular expression

Need help with a regular expression

(OP)
I have a string that I read in from a text file in the format of:

string1|string2|string3|string4|...

where '|' is the delimiting character. i need to come up with a regular expression that will allow me to parse these strings with ereg to put into an array.

so far I have something like

ereg("(^.|.*)|(^.|.*)|(^.|.*)", $BUFFER, $temparray);

But this must be wrong can someone help me?

thanks.

RE: Need help with a regular expression

(OP)
I failed to mention in my post that the strings could contain any sequence of characters including &*^%$#@!~` etc. etc.

I can't figure out the correct regular expression which takes

blah, blah, blah!|http://www.blah.com?balh=blah&;blah2=blah%20blah

and parsing it using ereg so that the strings in the array turn out to be

blah, blah, blah!

and

http://www.blah.com?balh=blah&;blah2=blah%20blah

thanks in advance

RE: Need help with a regular expression

I'm not that familiar with "ereg", but if all you want to do is split up a line into tokens based on a delimiter, then look at "split", "explode", "strtok" - here's how you could use split:

   $a = "xxx|yyy|zzz";
   $token_array = split("|", $a);

And if you want to get everything before http in

 blah, blah, blah!|http://www.blah.com?balh=blah&;;blah2=blah%20blah

then you could use something like this:

   $a = "blah, blah, blah!|http://www.blah.com?balh=blah&;;blah2=blah%20blah";

  list($before_http, $rest_of_line) = split("http", $a);

but of course $rest_of_line would *NOT* contain "http" since we used that as the delimiter.

Not exactly sure what you're looking for, but maybe this will point you in the right direction.
