How can I find this hash tag #test in the string?
preg_replace("/\b#test\b/i", "Found", $string);
It has to be with the # symbol!

I dont… understand. You’ve already got a regex for finding the word “#test” within a string.
I’m as perplexed as @StarLion.
Do you have a string that fails to replace the hash tag #test with “Found” that you can give us?
Or can you be more specific as to why what you have isn’t working?
When I use:
preg_replace("/\b#test\b/i", "Found", $string);
It doesn’t replace anything!
When I remove # and use:
preg_replace("/\btest\b/i", "Found", $string);
It works!
But the problem is that the string could contain many test
words and only one #test
so it will replace all of them!
I need to somehow make it search for #test not test
What is the value of $string?
$string = "this is a test string and this is a #test hash tag";
echo preg_replace("/\b#test\b/i", "Found", $string);
Buddy could you compile the REGEX for me please?
Here is what I have
\B(#test)\b
Matches the following:
test #test test
test.#test test
test. #test test
Does not match the following
test#test test
test.#testtest
test. #testtest
Get an error:
preg_replace(): Delimiter must not be alphanumeric or backslash
I didn’t put in the delimiter, so you must use
preg_replace("/\B(#test)\b/i", "Found", $string);
Is that second result a valid one, though?
No idea. That is up to him
WORKS great thanks cpradio
