Built-in web server prints HTML tags in terminal when address is wrong

Description

I tried to start the built-in web server, but I mistyped the address and then the PHP cli printed HTML tags in the terminal.

- php -S 0.0.0.0:8080
+ php -S 0.0..0:8080

Resulted in this output:

$ php -S 0.0..0:8080
[Wed Dec 15 11:54:39 2021] PHP Warning:  Unknown: php_network_getaddresses: getaddrinfo for 0.0..0 failed: Name or service not known in Unknown on line 0
<br />
<b>Warning</b>:  Unknown: php_network_getaddresses: getaddrinfo for 0.0..0 failed: Name or service not known in <b>Unknown</b> on line <b>0</b><br />
[Wed Dec 15 11:54:39 2021] Failed to listen on 0.0..0:8080 (reason: php_network_getaddresses: getaddrinfo for 0.0..0 failed: Name or service not known)

But I expected this output instead:

$ php -S 0.0..0:8080
[Wed Dec 15 12:01:43 2021] PHP Warning:  Unknown: php_network_getaddresses: getaddrinfo for 0.0..0 failed: Name or service not known in Unknown on line 0
