PHP Bangla Tutorial Part 16 (PHP While Loop)

PHP=Hypertext Preprocessor.
PHP is a server-side scripting language.
PHP first name was a personal home page.

Using PHP, we can easily create a dynamic website. As an example- Facebook, Yahoo, Flickr are created using PHP.

Dynamic means what user want and change feature demand of the user. Facebook is the best example of a dynamic website.

The loop is same as all programming language. Using loop you can execute any code block. As an example- your friend tells you to show output 1 to hundred.What can you do?If you use the paper you write easily but if you coding this method using a loop you can do very easily only two line.

PHP loop is very important for big PHP project. If you create a database using PHP loop you can query easily and get this data.

There are four loops in PHP. I discuss all loop in PHP.

1)While Loop: While loop syntax is: at first initialize a value second condition and third increment/decrement.Example: while statement;

2)For Loop: This is same but one difference all expression must be the same line. example-for initialize condition;increment/decrement

3)Foreach Loop: When we work array then we use a foreach loop. example- foreach array as value and for each array as the key equal value

4)Do while loop: Difference between while and do while loop is: while loop first checks the condition and give output but do while loop first one output then checks condition.

Loop is very important for any programmer.
