PHP - Day & Night

Hello all, i just joined today, because am going nuts with php and the include or require statement/function

I want to use them to link to a header. Nothing hard about that , I would say. But my bit of code below just does not work.

I am running them in a test area on my server. Just to be safe The file L2.php is in the same directory/folder ( showing my age).

 

I should  say that am have been programming a while but only using php for about 4 weeks and this normal simple bit of code has me stumped.

 I am building the site in visual studio and atom.

 any pointer would be received with joy

 

The content of L" is also below .

<?php include_once('L2.php'); ?>

centents of l2.php below

<h3>  line 2   <br><H2>Hello world AM TRYING 6</h2> </h3>

 

I've messed around with this for three hours now, and it's driving me batty.  I'm running the following Query:

mysql_select_db("myDB", $con);
$query = "UPDATE mytable SET Name = '$Name', Address = '$Address', City = '$City', State = '$State', Zip = '$Zip', Phone = '$Phone', Website = '$Website', Type = '$Type' WHERE id = '$ID'";

The problem is that it's not updating my database.  I've tried everything.  I've forced the page to Echo out the variables so that I know they're right.  I've run (successful) Delete queries to make sure I'm connecting to the right table.  I've forced it to spit out the variables at the end of the Update.   Everything I've tried works beautifully... except the Update itself.  It doesn't error out or anything- it acts like it's Updating, but the data never changes.  I can add to the database and delete from it, but it refuses to let me Update anything. 

I've looked all over the net, and tried every variation I can find.  Nothing works.   I also tried this:

$query = "UPDATE `testbed` SET `Name`=[$Name],`Address`=[$Address],`City`=[$City],`State`=[$State],`Zip`=[$Zip],`Type`=[$Type],`Phone`=[&Phone],`website`=[$Website] WHERE `ID`=[$ID]";
 
And

$result = mysql_query("UPDATE mytable SET Name = '$Name', Address = '$Address', City = '$City', State = '$State', Zip = '$Zip', Phone = '$Phone', Website = '$Website', Type = '$Type' WHERE id = '$ID'");

None of them do anything at all.

 I have questions but I also have some good info to share about putting your software in the cloud.  

The situation:

Some of you may have read about the nightmare stories. A developer had a infinite loop in his code that ran all night. This code did things inefficiently that devoured CPU in each iteration. This developer, greatly skilled,  opened his email the next morning and saw a email bill from his cloud provider totaling for $75K. True story. 

Most cloud providers let you define CPU usage thresholds that, when breached, send you a warning but these thresholds, if I understand them, are per account. 

It would seem the claim that cloud resources are available in whatever amounts you need, CPU, disk space, enough RAM to never have to wait on a page faults, etc... the claim that the cloud provides you with infinitely elastic  resources in an "all you can eat for one price" contract smells just a like a little like 💩

I did cloud development for many years with ServiceNow starting when it was a help desk and I watched it evolve into one of the best cloud development platforms out there. At one customer site I installed and managed it it out of the cloud and saw its insides and I can tell you its core code is not so terribly efficient. IMHO the cloud DOES take away 90% of a developer's worries about app performance..

If you call ServiceNow tech support and your problem is diagnosed as a performance issue with your code the first thing they will ask you is "did you follow the developer best practices"? They will politely say "sorry. Here's a link to them implying "fix your code". 

Questions: 

PHP Functions that devour CPU and where there is a better way?

What PHP functions or code techniques waste CPU? I am using similar_text and it does the job but it is slow. Better way?

What is the best way to measure CPU used by a PHP script or by a particular code module, defined as a set of related functions that fulfill a common purpose or by a single line of code? The purpose being to identify inefficient modules of code and improve them and even if the code is damn near perfect then at least can know what code modules are the most expensive.

CPU killin users (and developers too), how can they be identified?

I need to store data on cumulative CPU usage for any of the above and compare it with the free amount they give you and warn CPU hogs before they breach a threshold and generate $75K bills that were not in the plan.

Any info you have on avoiding surprise $75K CPU bills from a cloud provider are welcome
