Description: ------------ fsockopen in php5 seems to be pickier about requiring the stream transport specification ( 'tcp://', 'unix://', etc ) when opening sockets. PHP 4 would allow you to do... $fp = fsockopen( '/tmp/example.sock, 0, $errno, $errstr, 30 ); PHP 5 requires $fp = fsockopen( 'unix:///tmp/example.sock, 0, $errno, $errstr, 30 ); As Net_Socket::connect uses fsockopen and pfsockopen, it should be able to handle the transport specification, and currently doesn't. Reproduce code: --------------- $socket = &new Net_Socket(); $socket->connect( 'unix:///tmp/example.sock', 0, true, 30); Expected result: ---------------- A unix socket should get opened Actual result: -------------- If your /etc/resolv.conf contains.. search example.com Net_Socket tries to open a tcp socket to a host named unix:///tmp/example.sock.example.com 6294 socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4 6294 connect(4, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("www.xxx.yyy.zzz")}, 28) = 0 6294 send(4, "\254\320\1\0\0\1\0\0\0\0\0\0\21unix:///tmp/example.sock\5example\3com\0\0\ 1\0\1", 45, 0) = 45 6294 gettimeofday({1107447499, 264462}, NULL) = 0 6294 poll([{fd=4, events=POLLIN, revents=POLLIN}], 1, 5000) = 1 6294 ioctl(4, FIONREAD, [100]) = 0 6294 recvfrom(4, "\254\320\205\203\0\1\0\0\0\1\0\0\21unix:///tmp/example.sock\5example\3 com\0\0\1\0\1\300\36\0\6\0\1\0\0p\200\0+\3dns\3itd\300\36\nhostmaster\300\36\v\3 63k\20\0\0p\200\0\0008@\0$\352\0\0\0p\200", 1024, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("www.xxx.yyy.zzz")}, [16]) = 100 6294 close(4) = 0
