PHP解析错误，无法看到它

Error:

parse error line 8 not expecting ','

I just don't see it, maybe been in front of this PC too long:

$dbc =  mysql_connect('localhost', 'xxxx', 'xxxxxx', 'xxxxxxx')
        or die('error connecting');

$addcontact = "INSERT INTO `user`(`ID`, `Name`, `Comments`, `GPS String`, `IP Address`)".
        "VALUES('100003','john','blah','xxxxxxx','192.168.5.5')";

$result = ($dbc, $addcontact)
            or die('error querying');

echo("contact added");
mysql_close ($dbc);

I think you forgot the function name here:

$result = ($dbc, $addcontact) or die('error querying');

Something like...

$result = mysql_query($dbc, $addcontact) or die('error querying');

... would probably work.

Even better would be (as suggested by @Chitowns24) to use MySQLi, which means you should use mysqli_connect and mysqli_query for those functions.

Are you are trying to specify a database in your connection string? You can do that with mysqli, but not with mysql.

mysqli_connect('localhost', 'xxxx', 'xxxxxx', 'database');

Assuming you want to continue using mysql and not mysqli:

<?php

$db = mysql_connect('host', 'username', 'password');

mysql_select_db('database', $db);

// Go on with your querying and such...

?>
