Iterate with index in PHP

In PHP, we can iterate over an array with index using the foreach loop or a traditional for loop.

Using foreach loop:

$fruits = array("apple", "banana", "mango", "orange");
foreach($fruits as $index => $fruit) {

  echo "Index: " . $index . ", Fruit: " . $fruit . "
";

}

Output:

Index: 0, Fruit: apple
Index: 1, Fruit: banana
Index: 2, Fruit: mango
Index: 3, Fruit: orange

Using for loop:

$fruits = array("apple", "banana", "mango", "orange");
 
for($i = 0; $i < count($fruits); $i++) {
   echo "Index: " . $i . ", Fruit: " . $fruits[$i] . "
";
}

Output:

Index: 0, Fruit: apple
Index: 1, Fruit: banana
Index: 2, Fruit: mango
Index: 3, Fruit: orange

In both cases, we are iterating over the array and printing the index and element value of each item. In the foreach loop, we use the $index variable to hold the index of the current item as we iterate over the array. In the for loop, we use the $i variable to keep track of the current index as we iterate over the array.
