How to extract a value from a key= value pair in a string via regex

JS:

  // Extract the data from in the form of "key=value" string, position is in case the value has more than one "="
  private getDataFromString(str: string, search: string = '', position = 0) {
    const regex = new RegExp(`${search}\\s*=\\s*([^,\n]+)`);
    const match = str.match(regex);

    if (match === null) return '';

    const split = match.at(1)?.split('=');

    return split[position].trim();
  }

PHP

    private function find_in_str($key, $text)
    {
        $delimiters = ",\n;";
        $results = [];

        $regex = "/$key\s*=\s*([^$delimiters]+)/";
        $match = preg_match($regex, $text, $results);

        if (! $match) {
            return '';
        }

        return trim($results[1]);
    }
