Differentiate For each and While loop.

Answer in Brief

	While loop	Foreach loop
Working principle	The while statement will execute a block of code If and as Song as a test expression, is true.	The foreach statement is used to loop through arrays.
Working principle	If the test expression is true then the code block will be executed. After the code has executed the test expression will again be evaluated and the loop will continue until the test expression is found to be false.	For each pass, the value of the current array element is assigned to $value and the array pointer is moved by one and in the next pass, the next element will be processed.
Syntax	`while(condition) { code to be executed; }`	`for each ($array as $value) { code to be executed; }`
