You may also checkout PHP & Mysql for Dummies. Those are pretty good starting points as well.

It is complaining that Connections\PhoenixDB.php doesn't exist. If it does exist it isn't being found. Is your web server Windows? If not you're using the wrong slash. Unix-like server use / to separate folder names. You could also be more specific as to the files location: \directory\another\Connec...

This line make no sense: You don't have such a variable. Instead you should use $user.

Try print_r($user) and you'll see the resulting array from mysql_fetch_array.

As a rule I avoid using variables to store data which is related to other data or has more than one value. This is something you want to avoid: $firstname1 = "John"; $firstname2 = "Steve"; That will be very difficult to work with. Instead if you store your data in an array (or ob...

I'm not sure I understand your question. Here is how I'd do this: When user logs in check $_SESSION for stats. If unset, query the table for stats. Save the stats into $_SESSION as an array. If the stats change, update the database and update the $_SESSION array. With this method you only need to SE...

As far as I understand it you'd wind up with a cached version of php files as they are used. In other words the functions.php file would be cached right off the bat. The files that are required will be cached as they are actually used. When the files change, or you run out of cache memory older file...

Yes though you'd need to tell the web server than captcha.png is actually a PHP file and should be processed as such. If you're using Apache you can do this with a .htaccess file something like: <FilesMatch "^captcha.png$"> ForceType application/x-httpd-php AcceptPathInfo On </FilesMatch>

Here is how I'd approach this: I like to store dates in MySQL as "datetime" then convert to whatever I want. In your case I'd: Convert the time the user submitted: $timestamp=strtotime($_POST["time"]); // $timestamp is now a timestamp of 5pm $saveme=date("G:i", $timesta...

Actually you got it right. You want to print the header information before readfile outputs the zip. $file_output is a bad name though. It's really $header_output. The file will be outputted using readfile(). readfile() will open and print the file all at once. As for security you're alright so far....

No problem here is a quick demo: // Capture output from here on down... ob_start(); print "This won't actually be displayed until latter."; // Save the buffered output into a variable. $my_output=ob_get_contents(); // Stop buffering and clear the results from memory ob_end_clean(); // Now ...

Well your ob_start and ob_end_clean are preventing the headers from being sent. You're buffering them but not outputting the buffer.

You'd need a ob_get_contents(); and an echo or print.

So far it sounds right to me. I guess you'll want to group data for each message by it's ID.

You could either do this logic for this in PHP or perhaps two queries. One to get the messages, and other to get the TO and FROM data.

I prefer to fetch results and save the data into an array. I then use the array latter to output. // Save results into an array $people = mysql_fetch_array($result_set); // now output foreach($people as $person) { if($person['filtering_category''] == 1 ) { print $person["First_Name"]; prin...

The problem is probably with your $member array. I suspect your array is actually: $member[0]["username"] not $member["username"] You can verify this by adding in: print "<pre>"; print_r($member); print "</pre>"; // or print "<pre>"; print_r($_SESSIO...

Sounds like one of two issues: #1 what welry said. You have two different users and need to trigger refreshes. or #2 You submit the form and are displaying old data. In the case of #2 this is a problem with your logic. Your script is pulling in the data before it is updated to the DB. You'll either ...
