*   SYNTAX:
*   for (initialization; condition; increment)
* 	{
*   code to be executed;
*  	}

*  The WHILE loop will execute a block of code IF and as long as a test expression is true.

*  until the test expression is found to be false.

* 																									   
*  The PHP continue keyword is used to halt the current iteration of a

*  statement block containing the code that the loop executes, preceded by a 
*  conditional test. For the pass encountering continue statement, rest of the 
*  loop code is skipped and next pass starts.
