How to Convert Dot-Delimited Strings to Multidimensional Arrays in PHP?

Convert Dot Syntax to Multi-Dimensional Array in PHP

Converting dot-delimited namespace strings to multidimensional arrays can be a valuable tool for parsing and restructuring data. To achieve this, consider the following approach:

Optimal Solution:

The optimal solution involves using a recursive function that traverses the dot-delimited string and creates the corresponding array structure. Here's the code:

function assignArrayByPath(&$arr, $path, $value, $separator = '.') {
    $keys = explode($separator, $path);

    foreach ($keys as $key) {
        $arr = &$arr[$key];
    }

    $arr = $value;
}

How it Works:

1. explode($separator, $path): This splits the dot-delimited string into an array of keys.
2. The foreach loop iteratively traverses the keys, accessing the corresponding array elements using the &$arr reference.
3. The assignment $arr = $value assigns the provided value to the final array element.

Example:

Using the code:

$source = [];
assignArrayByPath($source, 's1.t1.column.1', 'size:33%');

Will result in:

$source['s1']['t1']['column']['1'] = 'size:33%';
