The code is correct, so it sounds like you're either not running it on a machine that has PHP, or you're not accessing the file through a web server. Make sure when you run the file that the URL that the browser shows starts with http:// and not something else.

I am running it on localhost so it shows:file:///C:/xampp/hello1.php. When im running the following code it displays correctly, so i dont understand why the others wont execute and its url is: file:///C:/xampp/www/welcome.html<!DOCTYPE html PUBLIC "-//W3C//DTD? XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/? xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/? 1999/xhtml" xml:lang="en"?lang="en"><head><meta http-equiv="content-type"? content="text/html;? charset=utf-8"/><title>Welcome to this Page!? </title></head><body><h1>This is a basic XHTML page!? </h1><br /><p>Even with <span style=?"font-size: 150%;">some</span>? decoration, it's still not very? exciting.</p></body>

You are opening the file localy which wont execute php. You need to use http://localhost/location/to/your/file.phpAlso you need to put the file in web root. In xampp there a 'htdocs' dir which is webroot in xampp

My root is file:///C:/xampp/htdocs/mylife.php, thats what it shows. I have used xammp before and it worked, i could execute my files from any folder just as long as its routed correctly. Why is the the previous code working and not the last one, thats the problem or what im asking? The code is executing just not the <?phpprint "Hello, world!";?> When i put it http http://localhost it automatically direct it to file:///C:/xampp/htdocs/mylife.php. Whats wrong?

Code inside php block will not be parsed as php unless you call the page via webserver eg localhost. Other html code will be sent to browser as text and will be interpreted and shown as html pageYour can execute your page from http://localhost/myfile.phpWhat do you see when you run it

When i run this code:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <title>Hello, World!</title></head><body><p>The following was created by PHP:<?phpprint "<span style=\"font-weight:bold;\">Hello, world!</span>";?></p></body></html> It executes on the server, but its not making the "Hello, World" bold and reads like this: The following was created by PHP: Hello, world!" ?> Is there a quotation to many or any brackets that should not be there?

It's still the same problem. Double-clicking on a file to run it does not execute PHP. PHP is set up with your web server. Therefore, if you want to execute PHP you need to use the web server. Double-clicking on the file does not use the web server, it just opens the file in the browser and the browser displays the PHP code as text. You need to use http://localhost to access your page through the web server, which will execute PHP. That's the only way to do it through the web server. If you don't do that then you're not going to have the PHP code executed.

The answer is not here cause i've been doing it like you guys said and its not working!It keeps on giving me this "; ?> on every page/code i do. Seems to only print the html or partially php...I saw post on the phpini file that needs to be set to on and not off, can this be it. In the xampp php file is php.ini-development and php.ini-production

the simplest page I can think of to test/verify PHP is

<?phpinfo();?>

otherwise, as has been mentioned1) make you are actually running a web server locally, not sure which one you use, WAMP/MAMP are popular options. 2) make sure the file is in the webroot, either www or htdocs, depending on the server. 3) Then you have to make sure you access the file over http://localhost/path/to/file. those are the minimum requirements.

The answer was given above. go onto a different computer, when Xampp is on, and load the address;http://www.{IP OF THE MACHINE YOU'RE HOSTING XAMPP ON}/myfile.php and it'll work.

why would you send him to a different computer? If he does it correctly, he can just do it all locally.

To make sure it will work with short tags disabled, the phpinfo file should have this: 

<?php phpinfo();

If you save a PHP file with only that and nothing else in it, and pull it up in your browser, it will be very obvious whether or not PHP is working.

Thank you guys. I think it is the laptop thats the problem. I have run the same codes via an online server and it works! Another problem, when i run thiscode<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Greetings!</title></head><body><?php // Script 3.7 - hello.php ini_set ('display_errors', 1); // Let me learn from my mistakes!error_reporting (E_ALL | E_STRICT); // Show all possible problems! // This page should receive a name value in the URL. // Say "Hello":$name = $_GET[''];print "<p>Hello, <span style=\"font-weight: bold;\">$name</span>!</p>"; ?></body></html> I get this output: PHP Error Message Notice: Undefined index: Tony in /home/a9677473/public_html/hello.php on line 17

Hello, ! The html code is working fine and all seems to be in place, what am i doing wrong here?

Are you trying to run that page like this: page.php?=Tony You're looking for a value without a name, it would be better to give it a name: page.php?name=Tony And then look for the value of the name: $name = $_GET['name'];

have you looked at what's on/around line 17? undefined index means you have a problem with an array, specifically accessing one of its members. Probably your empty $_GET['']

When i run the code, it gives the following output: Hello, $name!"; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Greetings!</title></head><body><?php // Script 3.7 - hello.phpini_set ('display_errors', 1); // Let me learn from my mistakes!error_reporting (E_ALL | E_STRICT); // Show all possible problems!// This page should receive a name value in the URL.// Say "Hello":$name = $_GET['Celia'];print "<p>Hello, <span style=\"font-weight: bold;\">$name</span>!</p>";?></body></html><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Greetings!</title></head><body><!-- Script 3.6 - hello.html --><div><p>Click a link to say hello:</p><ul> <li><a href="hello.php?name=Michael">Michael</a></li> <li><a href="hello.php?name=Celia">Celia</a></li> <li><a href="hello.php?name=Jude">Jude</a></li> <li><a href="hello.php?name=Sophie">Sophie</a></li></ul></div></body></html> Im including the html code:
