Parse BBCode in array - php

Question

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?

Answer 1

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"
}
}
}
