(PHP 3 <= 3.0.18, PHP 4 >= 4.0.0)
mysql_connect -- Open a connection to a MySQL Server
Description
resource mysql_connect (string [server], string [username], string
[password])
Returns a MySQL link identifier on success, or FALSE on failure.
mysql_connect() establishes a connection to a MySQL server. The following defaults
are assumed for missing optional parameters: server = 'localhost:3306',
username = name of the user that owns the server process and password =
empty password.
The server parameter can also include a port number. eg. "hostname:port"
or a path to a socket eg. ":/path/to/socket" for the localhost.
Note: Support for ":port" was added in PHP 3.0B4.
Support for ":/path/to/socket" was added in PHP 3.0.10.
You can suppress the error message on failure by prepending '@' to the function name.
If a second call is made to mysql_connect() with the same arguments, no new link
will be established, but instead, the link identifier of the already opened link will be
returned.
The link to the server will be closed as soon as the execution of the script ends, unless
it's closed earlier by explicitly calling
mysql_close().

Example 1. MySQL connect example
<?php
$link = mysql_connect("localhost", "username", "secret")
or die("Could not connect");
print ("Connected successfully");
mysql_close($link);
?>
