Why doesn't the i modifier work in preg_match?

Question

PHP

Hello! Please, give me an idea why the i modifier in preg_match might not work? I need the recognizable phrase to be case insensitive, but the i modifier doesn't work :(
preg_match('/\btext\b/u', $message_text) another?
Thanks in advance!

Answer 1

Good evening.
Finds only one occurrence? Use preg_match_all.
Use the third parameter for preg_match_***, it gets an array with results.

Answer 2

Errcode 28 = No disk space . (or inodes)
I didn't really understand why you needed concat.

SELECT
  COUNT(DISTINCT `offer`) AS `cnt`,
  `webmaster`, `partner`
FROM `orders`
GROUP BY `webmaster`, `partner`
HAVING `cnt` > 1

Answer 3

If I'm not mistaken something like this:

SELECT `partner`, COUNT(1) as `count` FROM `table` GROUP BY `parthner` HAVING count>1
