I am doing magento2 developer training. I am working on exercise"Create a new router which “understands” URLs like /frontNameactionPath- action and converts them to /frontName/actionPath/action". In that exercise I come across the code

if (preg_match("%^/(test)-(.*?)-(.*?)$%", $info, $m)) {
    $request->setPathInfo(sprintf("/%s/%s/%s", $m[1], $m[2], $m[3]));
    return $this->actionFactory->create('Magento\Framework\App\Action\Forward',
    ['request' => $request]);
}

I want to know, What is % in regular expression "%^/(test)-(.?)-(.?)$%"?

These are just the delimiters on the regular expression and not part of the expression itself. My thinking is they used % and not the normal / so that the / in the regex itself would not have to be escaped.

  • Why this delimiter used? is this optional?

    @PMB I think they picked % over the "normal" / so as to avoid having to escape the / inside the expression itself. Apr 27 '17 at 9:29
