leszekj Posted May 3, 2006 Share Posted May 3, 2006 I have mySql, PHP and the Apache server installed on my computer. The database mySql works OK, the PHP as well but when I want to connect to the database on my local computer it seems not to work.In my php I have the following code:<body><?php$dbhost = 'localhost';$dbuser = 'root';$dbpass = 'cze00345';echo 'check 1';$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql');$dbname = 'test';echo 'check 2';mysql_select_db($dbname);echo 'check 3';mysql_close($conn);?> </body> The browser displays only "check 1", nothing more, so I suspect that there is something wrong with the "$conn=mysql_connect(..." instruction - it may not connect to the database."root" and "cze00345" are the user and password I am using in the "mysql -h localhost -u root -p" instruction while reaching the database from the DOS window.I am wondering whether there is something more I should do in order to connect to the database via PHP.

wildteen88 Posted May 3, 2006 Share Posted May 3, 2006 Do you not get the [b]Error connecting to mysql[/b] message which you has setup when the mysql_conncet function fails.Is this a local install of Apache/PHP/MySQL on your PC? If so which version of PHP are you using? If its PHP5 did you enable the mysql extension and setup the extension_dir directive too in the php.ini?Also it would be a good idea too to enable display_errors too. As then if there is an error in your php script PHP will report the errors rather tnan hidding them too.

I installed all about two months ago, and the versions are from that time - the version of PHP is 5.I put these instructions into the php.ini file:extension=php_mssql.dllextension=php_msql.dllextension=php_mysql.dlland also I set:display_errors = OnI does not work but I will try to restart the computer, and I will send a message.Thanks.

leszekj Posted May 3, 2006 Author Share Posted May 3, 2006 After I restarted the computer the error showed:Fatal error: Call to undefined function mysql_connect() in C:\Program Files\Apache Group\Apache2\htdocs\u1.php on line 14So, still there is something wrong.

ichversuchte Posted May 3, 2006 Share Posted May 3, 2006 The only think that I can see is that you are trying to us mysql connect to connect to $dbname - test before you call that varible. That might be why you stop at check1 and don't go any futher.Try[code]<?php$dbhost = 'localhost';$dbuser = 'root';$dbpass = 'cze00345';$dbname = 'test';echo 'check 1';$conn = mysql_connect($dbhost, $dbuser, $dbpass);if (!$conn) { echo("ERROR: " . mysql_error() . "\n"); }echo 'check 2';mysql_select_db($dbname);?> [/code] Link to comment https://forums.phpfreaks.com/topic/8952-cannot-connect-to-the-database/#findComment-32944 Share on other sites More sharing options...

leszekj Posted May 3, 2006 Author Share Posted May 3, 2006 I still have the problem and I do not have any idea what is wrong with the PHP code that cannot connect to the mySql server on my local computer.I changed the php.ini file, put the libmysql.dll into the Windows folder, I changed some other things in the php.ini and it does not work!It may be a small thing, and now I am considering the instructions in the php.ini file - whether they are correct. Should it be (I am using Windows XP):1. doc_root = "C:\Program Files\Apache Group\Apache2\htdocs"or2. doc_root = "C:/Program Files/Apache Group/Apache2/htdocs"or3. doc_root = "C:\Program Files\Apache Group\Apache2\htdocs\"or4. doc_root = "C:/Program Files/Apache Group/Apache2/htdocs/"The same with setting other directories:extension_dir = "c:\php\ext"extension_path = "c:\php\ext" (should I put this command?)Another thing is that the error may stick somewhere else. In the PHP configuration or in mySql itself? That is why I am giving here the screen of the result of the phpinfo():[div align=\"center\"][img src=\"http://www.palacyk.lap.pl/report.gif\" border=\"0\" alt=\"IPB Image\" /][/div]I have tried to fix this problem all day long today but failed so far. I am still trying. I put my php.ini file [a href=\"http://www.palacyk.lap.pl/php.ini\" target=\"_blank\"]here[/a].Oh, and I would forget to put the error reports that have appeared after my simple programme:[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'localhost' (10061) in C:\Program Files\Apache Group\Apache2\htdocs\u1.php on line 14Warning: mysql_select_db() [function.mysql-select-db]: Can't connect to MySQL server on 'localhost' (10061) in C:\Program Files\Apache Group\Apache2\htdocs\u1.php on line 17Warning: mysql_select_db() [function.mysql-select-db]: A link to the server could not be established in C:\Program Files\Apache Group\Apache2\htdocs\u1.php on line 17Warning: mysql_close(): supplied argument is not a valid MySQL-Link resource in C:\Program Files\Apache Group\Apache2\htdocs\u1.php on line 19[/quote] Link to comment https://forums.phpfreaks.com/topic/8952-cannot-connect-to-the-database/#findComment-33086 Share on other sites More sharing options...
wildteen88 Posted May 3, 2006 Share Posted May 3, 2006 You dont need to setup the doc_root directive in the php.ini.Now you should only have a directive called extension_dir and not extension_path in your php.ini. And it should be in this format:[code]extension_dir = "C:/php/ext"[/code]Now when make chnages to the php.ini save it and then [b]restart[/b] your Apache/IIS web server for the changes to affect.
