how to convert string to array?

Question

Please, help solve the problem. I have a string like this:

[MoveNode(node='/html/head/meta[6]', target='/html/head[1]', position=22), MoveNode(node='/html/body/div[1]/main/div[1]/div/div/div/div/div[2]/ul/li[1]/a[1]', target='/html/head[1]', position=15), RenameNode(node='/html/head/a[1]', tag='meta'), InsertAttrib(node='/html/head/meta[6]', name='content', value='text text text text (text text), text'), InsertAttrib(node='/html/head/meta[6]', name='name', value='description'), DeleteAttrib(node='/html/head/meta[6]', name='href'), DeleteAttrib(node='/html/head/meta[6]', name='title'), UpdateTextIn(node='/html/head/meta[6]', text=None), MoveNode(node='/html/body/div[1]/main/footer/ul/li[2]/a[1]', target='/html/head[1]', position=16), RenameNode(node='/html/head/a[1]', tag='meta'), DeleteNode(node='/html/body/div[1]/main/div[1]/div/header/div/div/div[2]/div/h6[1]'), DeleteNode(node='/html/body/div[1]/main/div[1]/div/header/div/div/div[2]/div[1]')]

I need to convert this string to such an array. How to do it?

Array
(
    [MoveNode_1] => Array
        (
            [node] => /html/head/meta[6]
            [target] => /html/head[1]
            [position] => 22
        )
...
    [InsertAttrib_4] => Array
        (
            [node] => /html/head/meta[6]
            [name] => content
            [value] => text text text text (text text), text
        )

    [InsertAttrib_5] => Array
        (
            [node] => /html/head/meta[6]
            [name] => name
            [value] => description
        )
...

    [MoveNode_9] => Array
        (
            [node] => /html/body/div[1]/main/footer/ul/li[2]/a[1]
            [target] => /html/head[1]
            [position] => 16
        )
...
)

Tried to solve like this

$str = '....'; 
$arr0 = explode("), ", $str);
$arr2 = [];
$i = 1;
foreach ($arr0 AS $arr1) {
    $arrs = explode("(", $arr1);
    parse_str(str_replace(['\'', ', '], ['', '&'], $arrs[1]), $output);
    $arr2[$arrs[0] . "_" . $i] = $output;
    $i++;
}
print_r($arr2);

But because of the brackets inside the text, the array is formed incorrectly

This looks like a print_r/var_dumped object. Where did you get this from? Should've generated a parsable format to begin with, instead of this debug output. — tkausl

This generates the code from the example. But he does it wrong. I showed how to get the ideal — User

"But because of the brackets inside the text, the array is formed incorrectly"; incorrectly how? please be more specific. — l'L'l

like this: ``` [InsertAttrib_4] => Array ( [node] => /html/head/meta[6] [name] => content [value] => text text text text ) [text'_5] => Array ( ) [InsertAttrib_6] => Array ( [node] => /html/head/meta[6] [name] => name [value] => description ) ``` — User

You can use a combination of preg_match_all and array_map to extract the function names, node strings, and key-value pairs from the string.

 $text = '[MoveNode(node=\'/html/head/meta[6]\', target=\'/html/head[1]\', position=22), MoveNode(node=\'/html/body/div[1]/main/div[1]/div/div/div/div/div[2]/ul/li[1]/a[1]\', target=\'/html/head[1]\', position=15), RenameNode(node=\'/html/head/a[1]\', tag=\'meta\'), InsertAttrib(node=\'/html/head/meta[6]\', name=\'content\', value=\'text text text text (text text), text\'), InsertAttrib(node=\'/html/head/meta[6]\', name=\'name\', value=\'description\'), DeleteAttrib(node=\'/html/head/meta[6]\', name=\'href\'), DeleteAttrib(node=\'/html/head/meta[6]\', name=\'title\'), UpdateTextIn(node=\'/html/head/meta[6]\', text=None), MoveNode(node=\'/html/body/div[1]/main/footer/ul/li[2]/a[1]\', target=\'/html/head[1]\', position=16), RenameNode(node=\'/html/head/a[1]\', tag=\'meta\'), DeleteNode(node=\'/html/body/div[1]/main/div[1]/div/header/div/div/div[2]/div/h6[1]\'), DeleteNode(node=\'/html/body/div[1]/main/div[1]/div/header/div/div/div[2]/div[1]\')]';

   $str = preg_replace_callback("/(?<!\\\)'.*?(?<!\\\)'/s", function ($m) {
    return str_replace(['(', ')', ','], ['&lpar;‎', '&rpar;‏', '&sbquo;'], $m[0]);
}, $text);

     preg_match_all('/([\w]+)\(([^)]+)\)/', $str, $matches);
            $functions = $matches[1];
            $nodes = $matches[2];
            
            $result = array_map(function ($function, $node) {
                preg_match_all('/(\w+)=([^,]+)/', $node, $node_matches);
                $keys = $node_matches[1];
                $values = $node_matches[2];
                return [$function => array_combine($keys, $values)];
            }, $functions, $nodes);
            echo "<pre>";
            print_r($result);
            exit;

the resulted array be like

Pretty much what I need, thanks! Only there is a problem. The text after ")" is removed. how to avoid it?
Found a solution. First, this text needs to be processed with this function: $str = preg_replace_callback("/(?<!\\)'.*?(?<!\\)'/s", function ($m) { return str_replace(['(', ')', ','], ['(‎', ')‏', '&sbquo;'], $m[0]); }, $text);
