It's a "Hello, World" code snippet. I have tried to run it using XAMPP, and I am using Dreamweaver to write the code. Upon execution, the page does not display "Hello, World!". What would have went wrong?
<!DOCTYPE html>
<head>
<title>Hello World | Hello and Welcome</title>
</head>
<body>
<?php
Echo "Hello, World!";
?>
</body>
</html>
You are trying to execute PHP code on an HTML page. All PHP files should have the .php extension (implied from the OP's comments). Change your filename.
PHP handlers don't work in .html pages for efficiency reasons. When you use .html instead of .php, you are telling the server not to embed PHP in that page, to save server resources.
Echo would be better as echo.
Is the file extension .php, not .html?
Is PHP configured on the web server?
Please check all those out.
Either you're not saving the file in a php extension so the PHP engine doesn't run on it or your server isn't set up properly
It's working fine on IDEOne
The answer to change the extension to .php is correct, because by default it would be a waste of server resources to actually read every file to see if it contains PHP code in order to decide whether it should execute PHP processing on it.
That said if you really wanted to you can probably configure the server to serve up any file extension as PHP, even a made up one. There's nothing magical about the extension other than how it's configured to be handled.
for hello world program in php just follow this tutorial
but before that you should have wamp server or xamp server on your pc(wamp/xmap are open source software's and easily can found on google)
your 1st php program code:-
<?php
echo "hello world";
?>
output:-
hello world
Tutorial :https://www.youtube.com/watch?v=7qtqzhdEX-c
after this tutorial you can able to move other intermediate level programs of php.
PHP is generally case sensitive (see: http://php.net/manual/en/language.variables.basics.php).
So try changing Echo to echo.

PHP code is not being executed, but the code shows in the browser source code

I am trying to do something basic with PHP and HTML first before I get into something big. However, my html page doesn't seem to be processing PHP correctly.
I have the following php code in my html:
<?php echo '<p>Hello World</p>'; ?>
However, the output on the html page is:
'Hello World' on one line
but:
'; ?>
follows hello world
How can I fix this so I get 'hello world'?
PHP doesn't run on browsers, it's executed on the server. To work with PHP on your local machine, you'll want to set up a server, and write in HTML and PHP in a file with a .php extension, not a .html one. The easiest way to get started would be to use xampp as a beginner.
It looks like you are trying to put php code inside a .htm or .html file.
I ran this code as just html and got the following:
Hello World
'; ?>
So, it is properly interpreting the <p></p> tags but everything else is meaningless to it and doesn't know what to do with what comes after it, so it just prints it as is.
To use php, you need to be doing it inside a .php file and you need to be accessing it from a server that recognises .php files. If you are doing this locally, simply opening the file in a browser won't work by default. You will need to setup a local web server that is running a version of PHP. if you don't have much experience, I recommend WAMP because it is easy to set up and run php with.
If you are doing this on a website that is actually hosted (not local), most of them have support by default for PHP, so if you are using a .php file and it isn't working, you should contact the host or read their documentation to figure out how to get their servers to interpret php files.
i want to start php programming.
i use Dreamweaver IDE and WAMP Server.
when i run codes, the php codes, doesn't execute.
when my html code, run correctly.
for example when i use the following code:
<html>
<head>Hello</head>
<body>
<h1>Hello</h1>
<?php
echo("echoString");
?>
</body>
</html>
the "Hello" Message shows on the screen but "echoString" doesn't show.
my WAMP Server Installed and worked correctly.
i see the html output in my browser.
thanks
use the file with .php extension instead of .html like yourfilename.php and place the file in www folder , run it by going to
localhost/youfilename.php
I create a new HTML file for my project using Dreamweaver and i added a simple php code:
<!DOCTYPE html>
<html>
<body>
<?php
echo "My first PHP script!";
?>
</body>
</html>
so far nothing is appearing while i open the file with google chrome and IE, any thoughts?
PHP has to be executed on the server. Upload it to a web server that supports PHP, or install your own web server locally such as WAMP. You then need to access the file with a URL rather than just opening it. A local URL will look like http://localhost/ or http://127.0.0.1/.
Your file also needs to have the extension .php if it contains PHP code. If you really want to use PHP inside a .html file, your web server will need to be set up specially to handle this.
PHP requires a webserver and an interpreter. Browsers cannot handle PHP on its own.
Look at XAMPP
A good idea to check if your php file is working properly is to load phpinfo function.
This function will show details about your PHP installation:
<?php
phpinfo();
?>
If what you see on the screen is this php code with the entire opening and closing tags (), then you are not running the page with PHP.
<!DOCTYPE HTML>
<html>
<body>
<?php
//printing
echo "<p>Hello, World</p>";
?>
</body>
</html>
This is suppose to be a basic hello world example but when I run it in the browser I get an extra "; ?>
Hello, World
"; ?>
Why is that?
EDIT: Yes the file extension is php
EDIT2: I created the file with Notepadd++. I ran the file by right clicking the file and open with chrome.
EDIT3: Okay so what I gathered is that I can't just run the file locally. I will try through a web server. Thank you for the responses so far!
I believe your problem is that you do not have a local server such as xampp.
I would suggest downloading xampp and then follow the instructions for running a php file.
Make sure you have .php as the file extension
You are probably not running your file through your web server, but you are opening it locally.
Make sure your url is something like http://localhost/myFile.php. And not c:\documents and settings\myName\Desktop\myFile.php.
"I created the file with Notepadd++. I ran the file by right clicking
the file and open with chrome."
You are saying your problem. PHP files are not like HTML files. They must be compiled before served.
For example:
<html><body><?php echo date("Y"); ?><body><html>
will be expected to show the system year. If you try to open it browser does not recognize PHP scripts and treats that function as a text and you see
echo date("Y"); ?>
Why don't you see <?php ? Because after <character, the browser thinks that there is an HTML tag coming.
If you run that PHP file correctly and then look at the source HTML you will see
<html><body>2014<body><html>
You must move the file to web server directory like c:\xampp\www or to c:\wamp\www.
Then run apache server.
After that open a browser window and type localhost/yourfile.php:80
80 could vary in according to your settings (Take a look at httpd.conf file).
so I'm basically brand new to web based stuff. My university has given me a cPanel hosted server. I need to implement some basic php functions for my main web page.
This is what my cpanel looks like if it helps:
So in my index.html file I have:
<!DOCTYPE html>
<html>
<head>
<title>Current Date/Time</title>
</head>
<body>
<h3>
<?php
date_default_timezone_set('UTC');
echo date("l");
echo "Hello World!";
?>
</h3>
</body>
</html>
But none of the php echo stuff is displaying. I'm not sure if my server actually knows what to do with an html file with php in it.
My instructors have told me: the php file needs to be deployed to public_html folder using the file manager in CPanel.
But i'm not really sure what needs to go into the .php file and how to get my .html file to utilize it.
Thanks for your patience.
Your file name needs to be .php. If the web server is set up with PHP (which I'm going to assume it is) then it will handle the php file fine.
Rename the index.html for now and by default the index.php will be the first page to load.
The file you are using is index.html. This means that it can only display static text and that's the reason why your PHP code is not working.
All you have to do is change the extension from .html to .php then your PHP code should work.
Although I would suggest you Google a few Intro. to HTML and PHP tutorials to get you going on the basics
The file's extension needs to be changed from *.html to *.php or the PHP won't execute, it'll just be treated like raw HTML.
Here's a quick very basic step-by-step of what's happening:
The client requests index.php
Your web server recognizes the *.php extension and tells PHP to interpret it
PHP parses the text looking for PHP code, and evaluates that code, then replaces the PHP code with the output of that PHP code (if any)
For example:
$strVar = 'world';
echo '<span class="contentText">hello ' . $strVar . '</span><br />';
is replaced with that code's output:
<span class="contentText">hello world</span><br />
The resulting HTML is then returned to the client as content to be rendered by the client's web browser
The client's web browser parses the HTML and renders a web page
