A few days ago I updated my test server to PHP 5.3.0. After doing that, even though Apache had not been touched in any way, all URLs containing 'localhost' pointing to PHP files (e.g. 'http://localhost/whatever.php') started being redirected to 'www.localhost.com' (e.g. 'http://www.localhost.com/whatever.php'). At first it didn't even occur to me that the problem could have anything to do with PHP. I checked 'c:\windows\system32\drivers\etc\hosts' and it still contained a line for '127.0.0.1 localhost'. I checked my network adapter configuration and IPv6 had not been added as a protocol. My Apache configuration files were untouched. I spent two days searching high and low for a possible cause, and along the way realized that the problem only occurred when PHP was involved: HTML files were being served without any redirection issues. When I replaced php.ini with an old version from a backup and everything went back to normal, so I fired up a diff application and, bit by bit, started replacing the contents of the newer php.ini with lines from the old one. I finally isolated the problem: the error_log line, which specified the absolute path to a log file (the same path that had been working fine with previous PHP versions). When the line is commented out, the redirection problem goes away. I double-checked the existence of the log file and made sure it was writable. I then tried moving it to a different directory (updating php.ini accordingly), but that didn't work either. I also tried changing the path from "C:\Apache\logs\php_error.log" to "file:///C:/Apache/logs/php_error.log" and that did make the redirection problem go away, but no errors are actually logged, even though 'log_errors' is properly set to 'On'. If I set error_log back to "C:\Apache\logs\php_error.log", the redirection issues comes back. Reproduce code: --------------- Line in php.ini: error_log = "C:\Apache\logs\php_error.log" Expected result: ---------------- Errors should be logged as usual. Actual result: -------------- Errors are not logged. Whether or not code contains any errors, browser (both IE and Firefox) gets redirected from http://localhost/path/to/script to http://www.localhost.com/path/to/script. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48793&edit=1
