PHP (PHP: Hypertext Preprocessor) is a scripting language that helps people make web pages more interactive by allowing them to do more intelligent, complex things. PHP code is run on the web server.
A website programmed with PHP can have pages that are password protected. A website with no programming cannot do this without other complex things. Standard PHP file extensions are: .php .php3 or .phtml, but a web server can be set up to use any extension.
History[change | change source]
PHP was first created by Rasmus Lerdorf in 1995. It is now developed and improved by a large team of people. Its name at first stood for Personal Home Page, but it was later changed to PHP: Hypertext Preprocessor; using its old acronym in the new name.
Example[change | change source]
An example Hello World program:
<?php echo "Hello, World!"; ?>
It is common to put PHP code inside a HTML document, for example:
<!DOCTYPE html> <html> <head> <title>Hello World</title> </head> <body> <?= '<p>Hello World</p>'; ?> </body> </html>
