Loop in PHP - For Loop

So we are going to understand the for loop.

As you know the loop is a re-execute of a block code for the some condition to be true.

For example, I will keep waking till I reached the temple. Here Temple is a condition and walk is the block of code to be executed.

The structure of the for loop as follow:
for  ( {initial value for the loop} ; { contion to be check } ; { initial value to be changed } )
{

}
