how to fetch multiple lines of one file in one array in php

I have log file which looks like below:

I want to build an array containing one block per position.

Ex-ex:

array[0][‘rawdata’] contains the first block from --f15a0000-A-- to --f15a0000-Z--,

array[1][‘rawdata’] contains the second block from --bb410000-A-- to --bb410000-Z--.

Can anyone please help me how to do that?

Read through the file and every time you find a -- in the beginning you either start or stop an array-entry.

$array = array();
$fh = fopen($file,"r");
$started = false;
while (!feof($fh)) {
  $line = fgets($fh);
  if($started) {
    $temp .= $line;
    if(strpos($line, "--") === 0 && strpos($line, "-Z-") > 0) {
      $started = false;
      $array[] = $temp;
    }
  }
  if(strpos($line, "--") === 0 && strpos($line, "-A-") > 0) {
    $started = true;
    $temp = $line;
  }
}
fclose($fh);
print_r($array);

I think this should do it

It seems like there is a pattern here so you could use a regex and preg_match_all. A regex such as 

--([a-z\d]+)-A--[\s\S]+?--\1-Z--

seems to work with your sample data.

The -- is literal.
[a-z\d] is a character a through z and \d is a number.
The + allows it to be one or more of those characters.
The () captures the group.
The -A-- is a literal search (the A seems to be a starting block.)
The \s\S is a white space or non-whitespace aka just keep searching
The +? is to find a match until the next string is found.
The next string we search is the same identifier we started with but with a Z for the closing block, --\1-Z--. The \1 is a back reference to the first capture group we created.

PHP usage: https://3v4l.org/rjtW7

preg_match_all('/--([a-z\d]+)-A--[\s\S]+?--\1-Z--/', $string, $matches);
print_r($matches);

Note the PHP usage requires starting and ending delimiters on the regex as well.
