[PHP] RE: regex question
I think there maybe a few ways to do this... One is
[EMAIL PROTECTED]@[EMAIL PROTECTED]
That basically says "find me the pattern where one non-at symbol is followed
by an at symbol followed by another non-at symbol"
So if you do
numMatch: 3
Array
(
[0] => Array
(
[0] => @
[1] => i@
[2] => [EMAIL PROTECTED]
)
[1] => Array
(
[0] => @
[1] => @
[2] => @
)
)
Well, where that fails is when you have @'s at the beginning or end of the
string and that's easy enough to do.. So that would mean three searches...
There's probably a way to integrate them into one without loosing integrity,
but it depends on what kind of regexp libs you have, I reckon. It also
depends on what you really are trying to do with this search. Consider
str_replace, strpos and strtr as well.
Thanks,
Carl

Subject: regex question
What pattern can I use to match ONLY single occurrences of a character in a
string.
e.g., "Some text @ and some mo@@re and [EMAIL PROTECTED], etc @@@.
I only want the two occurrences with a single occurrence of "@".
@{1} doesn't work; there are 4 matches.
Thanks

Oh, wait, you wanted to use RegEx. Sorry, can't help you there. :-)

You're making your expressions too complicated. To test for just that
string,
eregi("HTTP/1\.[01] 302", $output)
should work.

[PHP] Re: regex question
You could do it using the strpos() function to find the index of the first
occurance of "" and strrpos() for the last occurence. Then use
substr() to grab what you want...
