I am trying to build a self-hosted PHP site, but I am having trouble connecting to the database from my PHP script.
Please note the following
1). This code allows me to connect to MAMP from my terminus without problem so I know MySQL is working etc
mysql --host=127.0.0.1 --port=8889 --user=root -p
2) When I tried to build a site on a remote hosted platform, this code allowed me to connect from my php script to MySQL on the remove server, so I know there is nothing wrong with this code per se, but it didn't work on my computer.
defined('DB_SERVER') ? null : define("DB_SERVER","host");
defined('DB_USER') ? null : define("DB_USER","username");
defined('DB_PASS') ? null : define("DB_PASS","password");
defined('DB_NAME') ? null : define("DB_NAME","photo_gallery");
3 I have been able to run a self-hosted wordpress site on my computer, but I didn't establish the database connection for that (it's somewhere in the code) so I don't what I'm doing wrong. That site is accessible at the following path. http://localhost:8888/wordpress/ even though it is connected at port 8889 (according to mysql)
4 MAMP tells me that I can connect to the database from my own scripts using this format
Host localhost
Port 8889
User root
Password root
Therefore, I added this line
defined('DB_PORT') ? null : define("DB_PORT","8889");
to this group, like so
defined('DB_SERVER') ? null : define("DB_SERVER","host");
**defined('DB_PORT') ? null : define("DB_PORT","8889");**
defined('DB_USER') ? null : define("DB_USER","username");
defined('DB_PASS') ? null : define("DB_PASS","password");
defined('DB_NAME') ? null : define("DB_NAME","photo_gallery");
but it still didn't work. I'm being told database connection fails when I try to test it.
Any ideas?
EDIT. I tried to put the port next to the localhost but it's not working.
defined('DB_SERVER') ? null : define("DB_SERVER","localhost:8889");
defined('DB_USER') ? null : define("DB_USER","root");
defined('DB_PASS') ? null : define("DB_PASS","root");
defined('DB_NAME') ? null : define("DB_NAME","photo_gallery");
EDIT. The above code was in the config.php which was included into the database.php which is this
<?php
require_once("config.php");
class MySQLDatabase {
private $connection;
function __construct(){
$this->open_connection();
}
public function open_connection(){
$this->connection = mysql_connect(DB_SERVER, DB_USER, DB_PASS);
if(!$connection){
die("Database connection failed:" . mysql_error());
} else {
$db_select = mysql_select_db(DB_NAME, $this->connection);
if (!$db_select) {
die("Database selection failed: " . mysql_error());
}
}
}
public function close_connection(){
if(isset($this->connection)){
mysql_close($this->connection);
unset($this->connection);
}
}
public function query($sql) {
$result = mysql_query($sql, $this->connection);
$this->confirm_query($result);
return $result;
}
public function mysql_prep( $value ) {
$magic_quotes_active = get_magic_quotes_gpc();
$new_enough_php = function_exists( "mysql_real_escape_string" ); // i.e. PHP >= v4.3.0
if( $new_enough_php ) { // PHP v4.3.0 or higher
// undo any magic quote effects so mysql_real_escape_string can do the work
if( $magic_quotes_active ) { $value = stripslashes( $value ); }
$value = mysql_real_escape_string( $value );
} else { // before PHP v4.3.0
// if magic quotes aren't already on then add slashes manually
if( !$magic_quotes_active ) { $value = addslashes( $value ); }
// if magic quotes are active, then the slashes already exist
}
return $value;
}
private function confirm_query($result){
if(!$result){
die("Database query failed:" . mysql_error());
}
}
}
$database = new MySQLDatabase();
?>
