I recently tried to implement this script however I have had some problems with it recently.
$q=mysql_query("select * from users where id='".$row['gamertag']."'");
while($row = mysqli_fetch_array($mw2ranks))
{
echo "<tr><td> ".$i.".";
echo "</td>
<td>$q[username]
</td>
<td>More stuff will go here</td>
<td>More stuff will go here</td>
";
$i++;
}
Then I was thinking the code $q[username] would locate the username located in the data match up. This wasn't the case, can anyone tell me why?
you need to fetch the result after querying it:
$res = mysql_fetch_assoc($q);
Note the danger of SQL-injections as mentioned in the comments. also be aware that the MySQL_* methods are deprecated. use PDO instead.

I am tring to learn about the imap function, and I am struggling to understand:
$result = imap_fetch_overview($mbox,"1:{$check->Nmsgs}",0);
In particular $mbox,"1:{$check->Nmsgs}",0
PHP manual says it uses the X:Y syntax.
But I just cant get my head around it.
Please can anyone assist.
This is explained in the docs, which you should definitely start reading now:
When a string is specified in double quotes or with heredoc, variables
are parsed within it.
And follow this link: http://php.net/manual/en/language.types.string.php#language.types.string.parsing

I am new to PHP and having problems with printing values from database.
This is my code:
<?
$level = $db->Query("SELECT `level` FROM users WHERE `id` = '" . $data['id'] . "'");
$r2 = mysql_fetch_object($level);
?>
And this is what it looks like when I try to print it:
<?php
echo $r2;
?>
And when I try to echo it it doesn't print the value from level but it only loads half of the page.
I would really appreciate if someone could tell me what the problem is?
$level is a mysql result resource. Try adding the following
while ($row = $level->fetch_row()) {
var_dump($row);
}
The query is returning a result resource. You need to use that with a fetch function of some kind to retrieve the actual data. If you're using MySQLi, then you can use mysqli_fetch_row() or similar.

In learing mongo with php,I have a tiny problem,
that is all,any help would be great appreciated！
You need to read this MongoPHPQueries Page and probably before that you need to do as #RocketHazmat said and start with this MongoPHP Tutorial.
But here is something that might help you with the data you are trying to find.
$cursor = $collection->find(array("addressse.0.state" => "NY"));
The above will give you a cursor allowing you to iterate over each record that is returned. Hope this helps.
FYI - You need more than just that line above to get that to work. So follow the links.

I have this query and i am asking if i can print the result in PHP without saving the result in other table.
SELECT SUM(weekly_fees) FROM scout_cabs
You start by giving it an alias to output:
SELECT SUM(`weekly_fees`) AS `total` FROM `scout_cabs`
Then you parse it as any normal request via mysql.
<?php
$sql = "SELECT SUM(`weekly_fees`) AS `total` FROM `scout_cabs`";
$run = mysql_query($sql);
$result = mysql_fetch_assoc($run);
echo 'The sum of the query is: ' . number_format($result['total']);
It may also be worth looking into mysqli_ if you are not already using it, as mysql_ is now deprecated.

I am looking to create a simple url where I can add URL querys to it and then have these saved to a database.
This would be the format that i'm looking for
example.com?name=value1&email=value2
Could anybody help ?
Get the values on the script from $_GET, then put them in your database using PDO or MySQLi. I don't know your database structure so I can't really help any further:
// In index.php
echo $_GET["name"];
echo $_GET["email"];
// Put them in your database
