Edit report at https://bugs.php.net/bug.php?id=80067&edit=1 ID: 80067 Updated by: requinix@php.net Reported by: me at derrabus dot de Summary: Omitting the port in bindto setting results in "Failed to parse address" error -Status: Open +Status: Feedback Type: Bug Package: Sockets related Operating System: macOS 10.15 PHP Version: 7.4.10 Block user comment: N Private report: N New Comment: The documentation doesn't actually say that "0" is allowed. https://www.php.net/manual/en/context.socket.php > Used to specify the IP address (either IPv4 or IPv6) and/or the port number that > PHP will use to access the network. The syntax is ip:port for IPv4 addresses, > and [ip]:port for IPv6 addresses. Setting the IP or the port to 0 will let the > system choose the IP and/or port. Thus the allowed values are "0:0" and ":0". Previous Comments: ------------------------------------------------------------------------ [2020-09-06 21:17:00] me at derrabus dot de Description: ------------ Before php 7.4.10, it was possible to provide a "bindto" setting without a port via the socket stream context. With 7.4.10, a warning is raised and the stream is not opened. This breaks Symfony's HttpClient component, see https://github.com/symfony/symfony/issues/38081 for details. The attached test script reproduces the regression. Executing it on php 7.4.9 produces the expected result. On php 7.4.10, the script fails. If you change the "bindto" setting to "0:0", the script passes on both versions, 7.4.9 and 7.4.10. Test script: --------------- <?php $context = stream_context_create(['socket' => ['bindto' => '0']]); var_dump(file_get_contents('https://httpbin.org/get', false, $context)); Expected result: ---------------- string(200) "{ "args": {}, "headers": { "Host": "httpbin.org" }, "origin": "1.2.3.4", "url": "https://httpbin.org/get" } Actual result: -------------- Warning: file_get_contents(https://httpbin.org/get): failed to open stream: Failed to parse address "0" in /app/test.php on line 4 bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80067&edit=1
