Re: [PHP-DEV] [Discussion] Proposal: get_favicon() helper function

[kasper Sanguesa-Franz]

From my perspective it sounds more like a composer package than a PHP core function

Hi internals,

My name is Sepehr and I would like to propose a small helper function for PHP that extracts the favicon URL of a given page.

The function takes a URL, fetches the HTML, and returns the favicon URL as a string.

Possible signature:

get_favicon(string $url): ?string

The function would scan the HTML for common favicon declarations such as:

<link rel=“icon” href="">

<link rel=“shortcut icon” href="">

<link rel=“apple-touch-icon” href="">

If a favicon link is found, the function returns the URL. If not, it returns null.

The goal is to provide a simple built-in helper for a common task in web utilities and crawlers.

I would appreciate feedback on this. If it seems reasonable, I’d like to draft an RFC and request a wiki account to create the proposal page.

Best regards,

Sepehr
