Previous Comments: ------------------------------------------------------------------------ [2008-01-12 18:15:23] hholzgra@php.net Calling the constructor without any argument is like calling mysqli_init() to create a mysqli object, it does not try to connect at all in this case but waits for an explicit call to mysqli::connect() or mysqli::real_connect() which allows to set mysqli::options() before connecting Reclassified as documentation bug as the documentation on the mysqli constructor is not clear about this. ------------------------------------------------------------------------ [2006-10-02 09:09:16] tony2001@php.net Assigned to the maintainer. ------------------------------------------------------------------------ [2006-10-02 09:04:02] camka at email dot ee This does not describe, why the first case does not give an error at all, even if the host is not reachable or does not exist: $m = mysqli(); // with no parameters ------------------------------------------------------------------------ [2006-10-02 08:54:51] tony2001@php.net NULL values passed as parameter to mysqli::__construct() have a special meaning, which are described in the docs. ------------------------------------------------------------------------ [2006-09-29 22:42:06] camka at email dot ee Description: ------------ If passing NULL parameters in mysqli::__construct, as they are by default, the values are not actually taken from php.ini (or apache conf) file. Tested with both 5.1.6 and 5.2 latest snapshot. Reproduce code: --------------- virtual host conf: php_admin_value "mysqli.default_host" zorro php_admin_value "mysqli.default_user" rootf php_admin_value "mysqli.default_pw" ff <? $m = new mysqli(); echo mysqli_connect_error(), "\n"; $m = new mysqli(null); echo mysqli_connect_error(), "\n"; $m = new mysqli(null, null); echo mysqli_connect_error(), "\n"; $m = new mysqli(null, null, null); echo mysqli_connect_error(), "\n"; ?> Expected result: ---------------- Access denied for user 'rootf'@'zorro' (using password: YES) Access denied for user 'rootf'@'zorro' (using password: YES) Access denied for user 'rootf'@'zorro' (using password: YES) Access denied for user 'rootf'@'zorro' (using password: YES) Actual result: -------------- [empty] Access denied for user 'rootf'@'localhost' (using password: YES) Access denied for user 'ODBC'@'localhost' (using password: YES) Access denied for user 'ODBC'@'localhost' (using password: NO) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38998&edit=1
