MarsSeed [1] filed a deletion request for php7-yaml [2]: Defunct package. It was meant to depend on php7, which no longer exists. It now depends on php, which is at v8+. Therefore this package is an outdated and wrongly named duplicate of AUR/php-yaml. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/php7-yaml/
