What is For Loops?

The For loop is a control structure that repeatedly executes a block of code until a condition is met. It’s commonly used to make a code block repeat itself a set number of times. It should be used if the number of iterations is given; otherwise, a while loop should be used. You use for loop when you already know how many times you want to run a block of code. It permits users to centralize all comments concerning the loop.

Syntax:-

for (init counter; test counter; increment counter) {
  code to be executed for each iteration;
}

The for loop in PHP is similar to the for loop in Java/C/C++. The following are the definitions of the (for loop) parameters:

initialization –It is used to set the counter variables and checked before the body of the loop is executed once unconditionally.
condition – At the beginning of each repetition, the state is assessed. The loop remains if it is true and the nesting statements are performed. If it is wrong, the loop is finished.
increment – The loop counter adds a new value. It is assessed at the end of every iteration.
