PHP Second Lesson

During this week I didn’t get a lot of time to work in PHP because I have a lot of work to do but still I learned something new and very important.

Basic PHP Syntax
A PHP scripting block always starts with . A PHP scripting block can be placed anywhere in the document.
A PHP file normally contains HTML tags, just like an HTML file, and some PHP scripting code.

Each code line in PHP must end with a semicolon. The semicolon is a separator and is used to distinguish one set of instructions from another.There are two basic statements to output text with PHP: echo and print.
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.

All this information I learned from www.w3schools.com.
