Run our First PHP Program
Hi, everyone, today we’ll start our first PHP program. Let’s make our first php application.
¶File Structure:
- Let’s create a folder in ypur
xampp/htdocs
namedphpclass
. - Then inside that folder create a file called
class1.php
. - And this
.php
is the extension of PHP file. - Every php file, we must have to declare as
.php
. PHP interpretor can interpret the file if it sees a.php
file.
¶PHP Code:
So, in our C:/xampp/htdocs/phpclass/class1.php
would be like this -
<?php
echo "Hello World. Welcome to PHP";
?>
¶Run on Browser
Now, go to your browser and run - http://localhost/phpclass/class1.php
And you’ll see this text in the browser -
Hello World. Welcome to PHP
Awesome, we’ve made our first PHP program and view that on the browser.
¶PHP Code with HTML:
So, after our first PHP program, it’s great right. Let’s improve it a little bit. PHP is a scripting language, we know. It’s actually an embedded language, means - it can be embedded inside HTML. WOW let’s see the above PHP code will work in a simple HTML file -
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>PHP Class 1</title>
</head>
<body>
<?php
echo "Hello World. Welcome to PHP";
?>
</body>
</html>
¶Run on Browser
Now, in browser, reload again - http://localhost/phpclass/class1.php
And you’ll see this text in the browser -
Hello World. Welcome to PHP
Great, so we’ve seen that we can inject PHP inside of an HTML body
tag.
