Iterate through an Array using For Loop in PHP

In this tutorial, you shall learn how to iterate through an array in PHP using For loop, with the help of example programs.

PHP – Iterate through an array using For Loop

To iterate through the elements of an array, we can use For loop. We initialize an index variable with 0, increment it during each loop iteration, and access the elements of the array using this index inside For loop.

The syntax to iterate through an array arr using For loop is

for ($i = 0; $i < count($array); $i++) {
  //$array[$i]
}

Examples

1. Iterate through an array using For Loop

In this example, we will take an array arr with some elements, and iterate through the elements of the array arr using For Loop.

PHP Program

<?php
  $arr = ["apple", "banana", "cherry"];
  for ($index = 0; $index < count($arr); $index++) {
    echo $arr[$index] . "<br>";
  }
?>

Output

Conclusion

In this PHP Tutorial, we learned how to iterate through elements in an array using For Loop.
