How to Iterate Over a Set in PHP ?

Answer

To iterate over a set in PHP, you can use the `foreach` loop.


✐ Examples

1 Iterate Over Set of Strings Using foreach Loop

In this example,

  1. We define a set named `mySet` containing string elements.
  2. We use the `foreach` loop to iterate over the set.
  3. Within the loop, we use the `as` keyword to assign each element to a variable.
  4. Finally, we execute the loop and process each string item in the set.

PHP Program

<?php
// Define set
$mySet = new DsSet(['apple', 'banana', 'orange']);

// Iterate over set of strings using foreach loop
foreach ($mySet as $item) {
    echo $item . "\n";
}
?>

Output

apple
banana
orange

2 Iterate Over Set of Numbers Using foreach Loop

In this example,

  1. We define a set named `mySet` containing numeric elements.
  2. We use the `foreach` loop to iterate over the set.
  3. Within the loop, we use the `as` keyword to assign each element to a variable.
  4. Finally, we execute the loop and process each numeric item in the set.

PHP Program

<?php
// Define set
$mySet = new DsSet([1, 2, 3, 4, 5]);

// Iterate over set of numbers using foreach loop
foreach ($mySet as $item) {
    echo $item . "\n";
}
?>

Output
