How to unload all phone numbers from text?

Question

PHP

Tell me, please, how to unload all phone numbers from a footcloth of text?
Here is an example of entering phone numbers:
1) 372 123456
2) 372123456
3) 372 12 34 56
4) 12 3456
5) text123456text

Answer 1

use regular expressions preg_match

Answer 2

Regular, but it will probably take too much, you still need to make a post check of all the results, or adjust this regular to the text (make the matching more strict):

preg_match_all("/\d{2,3}(?:\s*)\d+/", $input_lines, $output_array);

Answer 3

Download a free set of macros and add-ons Asap Utilites fo Excel (the Russian language is there on a regular basis).
Next, the "Text" menu, item 15 (well, 11, 13 at the same time). https://i.imgur.com/pjMjESR.png
