PHP - Using for loop with array


Using for loop with arrays:


     $names = ['A', 'B', 'C']; 
     for ($i = 0; $i < count($names); $i++) { 
         echo $names[$i] . " "; 
     } //from  w  w  w  .ja  v a2s .  com


Here, we have an array of names.

Since it is defined as a list, its keys will be 0, 1, and 2.

The loop initializes the variable $i to 0, and it iterates until the value of $i is not less than the number of elements in the array, that is, 3.

In the first iteration, $i is 0, in the second, it is 1, and in the third one it is equal to 2.

When $i is 3, it will not enter the loop, as the exit condition evaluates to false.

On each iteration, we print the content of the position $i of the array, hence the result of this code will be all three names in the array.
