I'd like to choose wether IPv4 or IPv6 to open the file so I'm using stream_context_create() with the 'bindto' option. 'bindto' with an ipv4 address is NOT working 'bindto' with an ipv6 address is working Reproduce code: --------------- The following code is working (ipv6 is used) -- $opts = array( 'socket' => array( 'bindto' => '[1:2:3:4:5:6]:0', ), ); $context = stream_context_create($opts); $contents = file_get_contents('http://other.server/my.file.dat', FALSE, $context); -- The following code is NOT working: -- $opts = array( 'socket' => array( 'bindto' => 'A.B.C.D:0', ), ); $context = stream_context_create($opts); $contents = file_get_contents('http://other.server/my.file.dat', FALSE, $context); -- => PHP Warning: file_get_contents(): Invalid IP Address: A.B.C.D Expected result: ---------------- ipv4 working Actual result: -------------- ipv4 NOT working ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48131&edit=1
