'for each loop' will- issue an error when you try to use it on a variable with different data type or an uninitialized variable.

'do while loop' is called exit-controlled loop.

'for loop' and 'while loop' are entry-controlled loops in looping structure.

Output:

There are three main parameters in for loop, namely the init counter, Test counter Increment counter.

For loop is used when the user knows in advance, how many times the block needs to execute. These types of loops are also known as entry-controlled loops.

Loops are used to execute block of statements, multiple times until the specific condition is met This helps the user to save both time and effort of writing the same code multiple times.

(i) foreach loop is exclusively available In PHP.
(ii) It works only with arrays. The loop iteration deepens on each KEY Value pair in the Array

1. init counter: Initialize the loop initial counter value
2. Test counter: Evaluated fer every iteration of the loop, If it evaluates to TRUE, the loop continues. If it evaluates to FALSE, the loop ends.
3. Increment counter: Increases the loop counter value.

To repeat the same block of code a given number of times, or until a certain condition is met. This can be accomplished using looping statements

do...while - loops through a block of code once, and then repeats the loop as long as the specified condition is true

PHP while loops execute a block of code while the specified condition is true.

The foreach construct provides an easy way to iterate over arrays

For loops execute a block of code a specified number of times.
