PHP is a server-side scripting language designed primarily for web development but also used as a general-purpose programming language. Originally created by Rasmus Lerdorf in 1994, the PHP reference implementation is now produced by The PHP Development Team. PHP originally stood for Personal Home Page, but it now stands for the recursive acronym PHP: Hypertext Preprocessor. Read more on Wikipedia...

Example from Riju:
<?php echo "Hello, world!\n";
Example from hello-world:
<?php echo 'Hello World';
<?php // Hello world in PHP echo 'Hello World!'; ?>
Example from Linguist:
#!/usr/bin/php <?php echo "PHP\n";
Example from Wikipedia:
class Person { public $firstName; public $lastName; public function __construct(string $firstName, string $lastName = '') { // optional second argument $this->firstName = $firstName; $this->lastName = $lastName; } public function greet(): string { return 'Hello, my name is ' . $this->firstName . (($this->lastName != '') ? (' ' . $this->lastName) : '') . '.'; } public static function staticGreet(string $firstName, string $lastName) { return 'Hello, my name is ' . $firstName . ' ' . $lastName . '.'; } } $he = new Person('John', 'Smith'); $she = new Person('Sally', 'Davis'); $other = new Person('iAmine'); echo $he->greet(); // prints "Hello, my name is John Smith." echo '<br />'; echo $she->greet(); // prints "Hello, my name is Sally Davis." echo '<br />'; echo $other->greet(); // prints "Hello, my name is iAmine." echo '<br />'; echo Person::staticGreet('Jane', 'Doe'); // prints "Hello, my name is Jane Doe."
