The replacement value of preg_replace has a subexpression value plus a value, as shown in the following simple replacement:
$ Ih = 100;
$ Aa = 'a123b ';
$ Aa = preg_replace ('/^ (a) 123 (B) $/I', '$ 1'. $ ih.' $ 2', $ aa );
Print_r ($ aa );

In this case, we're going to find out, in a set of data, the minimum value greater than 3, and the maximum value less than 9. First look at the table below.
A1:b3 This range is the data range. Next we start using the formula to find the minimum value greater than 3. Of course, with our own observation, we can directly find the minimum
