Question

PHP

Greetings. I'm new to RNR. I'm learning. I want to make a text parser with a record in the database according to the conditions. I figured out the principle of the function, but I just can’t move further, here’s where:
INTRODUCTION INFO:
There is the following text: (input was made by POST c TEXTAREA )

This is a list of Players and portals captured by them with coordinates (map link).
It is necessary that the arsil script writes all the listed information to the database, but ran into a problem: The player's name is written only once and the list of portals is below. By line-by-line parsing, I can (and can) output (and do something) only with those who have one line: no achievements.
And how to make those who have a large list added to the database with a nickname? I can add line by line, but without a nickname.
Tried to do nested instructions, but it doesn't work.
Tell me how to tell the function that if the line with the nickname and info about the medal - then parse the following lines up to the next nickname (or the second reset of the line, it is like an indent in the text), or at the end of the line "4 numbers and an empty next line". I tried s, \z, \Z, m (^ and $ put in expressions) but it doesn't work.
Help me please.
Here is the script

Answer 1

I would pervert like this:
Line by line looking for the presence of " https://www.ingress.com/intel " in the line.
If it is not found, then from this line we parse the achievement with the date or "achievement not found"
from all subsequent lines in which " https://www.ingress.com/intel " is found We take the list of portals assigned to the last found user into the database .

for($i=0;$i<count($list);$i++){
      if(stristr($list[$i], 'https://www.ingress.com/intel') === FALSE) {
            $login = 'парсим логин с $list[$i] и присваеваем';
      } else {
            $port = 'парсим данные портала и прочее с $list[$i]';
      }
      Кладём в БД $login $port;
}

Thus, we will shovel all the lines and put all the information in the database. You only need to clean $list[] from empty values ​​or filter it.
ps $list[] - list of received text strings.

Answer 2

It seems not difficult:
