It appears that fsockopen prior to php5 did not need the unix:// qualifier when opening a unix domain socket:
php4: fsockopen("/tmp/mysocket"......);
php5: fsockopen("unix:///tmp/mysocket"......);
This caught me out when upgrading.
unix:// e
udg://
unix:///tmp/mysockudg:///tmp/mysock
unix:// provê acessos a conexão via Unix
sockets. udg:// provê
um transporte alternativo para um socket Unix usando o protocolo
de datagramas de usuário (UDP).
Sockets Unix, diferentes de sockets de Internet, não esperam um
número de porta. No caso de fsockopen() o
parâmetro portno deve ser o valor 0.
Nota: Sockets Unix domain não são suportados no Windows.
