## PHP - Hello World
|
||
|
|
|
||
|
|
PHP scripts are executed on the server.
|
||
|
|
|
||
|
|
Before you continue you should have a basic understanding of the following:
|
||
|
|
|
||
|
|
### HTML
|
||
|
|
### CSS
|
||
|
|
### JavaScript
|
||
|
|
PHP files can contain Text, HTML, CSS, JavaScript, and PHP code.
|
||
|
|
A PHP script is executed on the server, and the plain HTML result is sent back to the browser.
|
||
|
|
|
||
|
|
A PHP script starts with `<?php` and ends with `?>`:
|
||
|
|
```php
|
||
|
|
<?php
|
||
|
|
// PHP code goes here
|
||
|
|
?>
|
||
|
|
```
|
||
|
|
or
|
||
|
|
you can also write A PHP script starts with `<?php` and ends without `?>`:
|
||
|
|
```php
|
||
|
|
<?php
|
||
|
|
// PHP code goes here
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
Below, we have an example of a simple PHP file, with a PHP script that uses a built-in PHP function "echo" to output the text "Hello World!" on a web page:
|
||
|
|
|
||
|
|
```php
|
||
|
|
<!DOCTYPE html>
|
||
|
|
<html>
|
||
|
|
<body>
|
||
|
|
|
||
|
|
<?php
|
||
|
|
echo "My first PHP script!";
|
||
|
|
?>
|
||
|
|
|
||
|
|
</body>
|
||
|
|
</html>
|
||
|
|
```
|
