Kod PHP dilaksanakan pada server, dan hasil HTML biasa dihantar ke pelayar.
Sintaks Asas PHP
Blok skrip PHP selalunya pada awalnya diletakkan <?php dan di akhiri dengan ?>. Blok skrip PHP boleh di letakkan di mana sahaja di dalam dokumen.<?php ?> |
A PHP file normally contains HTML tags, just like an HTML file, and some PHP scripting code.
Below, we have an example of a simple PHP script which sends the text "Hello World" to the browser:
<html> <body> <?php echo "Hello World"; ?> </body> </html> |
There are two basic statements to output text with PHP: echo and print. In the example above we have used the echo statement to output the text "Hello World".
Note: The file must have the .php extension. If the file has a .html extension, the PHP code will not be executed.
Comments in PHP
In PHP, we use // to make a single-line comment or /* and */ to make a large comment block.<html> <body> <?php //This is a comment /* This is a comment block */ ?> </body> </html> |
