PHP 8.4: Incorrect MIME content type

Description

The following code:

<?php

class Foo
{
    public function bar()
    {
        $this->baz(function () {});
    }
}

echo mime_content_type(__FILE__);

Resulted in this output in PHP 8.4:

application/javascript

But I expected this output, as in PHP <= 8.3:

text/x-php

Note that when you remove the function () {} snippet, it detects it as text/x-php.

Thank you!

PHP Version

So it might seem a database update issue, if I take data_file.c from 8.3 I get the proper mime type. @petk thoughts ?

One can check what file(1) reports (the version of file(1) is usually relevant). PHP 8.4 and master are currently using a patched 5.45; 5.46 has been recently released. We should likely update master, and possibly back-port a fix for this issue.

Good point file from debian unstable/ubuntu 24.10 is 5.45 both returns the same result whereas file on my mac, 5.41, returns php.

Looks like the issue has already been fixed for 5.46:

cmb@ELEPHPANT:~$ PATH=/home/cmb/file-5.46/bin:$PATH file -m ~/file-5.46/share/misc/magic.mgc -v file-5.46
magic file from /home/cmb/file-5.46/share/misc/magic.mgc
cmb@ELEPHPANT:~$ PATH=/home/cmb/file-5.46/bin:$PATH file -m ~/file-5.46/share/misc/magic.mgc --mime-type /mnt/c/php-sdk/phpdev/vs17/x64/gh17039.php
/mnt/c/php-sdk/phpdev/vs17/x64/gh17039.php: text/x-php

I have experience with updating fileinfo and patching it, I'll handle this.

I'll do the necessary backport for fixing this, but hold off the 5.46 update on master until a later time, just in case that a newer file version would be released before PHP8.5 enters feature freeze (to avoid double work)
EDIT: identified commit needed for backport: file/file@ad925d3
