I am trying to call a function from BBCode(like WordPress shortcodes). but I didn't find any code to do that, only I found HTML tag parser like:

[bold]Bold text[/bold]
->
<b>Bold text</b>

But I want to save it as an array, for example:

[date format="j M, Y" type="jalali"]

to something like this:

array(
    'date' => array(
        'format' => 'j M, Y',
        'type' => 'jalali'
    )
)

*Edited

I made a code to do this (sorry if my English is bad):

[date format="Y/m/d" type="jalali"] =>

Step 1: Get code between "[" and "]":
date format="Y/m/d" type="jalali"

Step 2: Explode space in the code:
$code = array('date', 'format="Y/m/d"', 'type="jalali"')

Step 3: Get shortcode name(offset 0 of $code) and get
difference($code excluded offset 0):
$name = 'date'
$attr = array('format="Y/m/d"', 'type="jalali"')

Step 4: Now I have attributes and code name. But the problem is if
put space in attributes value it will explode that too:
[date format="j M, Y" type="jalali"] =>
$code = array('date', 'format="j', 'M,', ' Y"', 'type="jalali"');

Now how can I fix this or get name and attributes with regex or anything else?

You can try this using regex

$code = '[date format="j M, Y" type="jalali"]';

preg_match_all("/\[([^\]]*)\]/", $code, $matches);

$codes = [];

foreach($matches[1] as $match) {
  // Normalize quotes into double quotes
  $match = str_replace("'",'"',$match);
  // Split by space but ignore inside of double quotes
  preg_match_all('/(?:[^\s+"]+|"[^"]*")+/',$match,$tokens);
  $parsed = [];
  $prevToken = '';
  foreach($tokens[0] as $token) {
    if(strpos($token,'=') !== false) {
      if($prevToken !== '') {
        $parts = explode('=',$token);
        $parsed[$prevToken][$parts[0]] = trim($parts[1],'"\''); 
      }
    } else {
      $parsed[$token] = [];
      $prevToken = $token;
    }
  }

  $codes[] = $parsed;
}

var_dump($codes);

Result:

array(1) {
  [0]=>
  array(1) {
    ["date"]=>
    array(2) {
      ["format"]=>
      string(6) "j M, Y"
      ["type"]=>
      string(6) "jalali"
    }
  }
}
