ProgramGuruIn PHP, you can access items in a set (implemented using an array or a Set class) using array iteration methods or specific set methods like in_array to check for item existence.
In this example,
$fruitSet with some initial values.<?php
$fruitSet = ['Apple', 'Banana', 'Cherry'];
foreach ($fruitSet as $item) {
echo $item . "\n";
}
?>Apple Banana Cherry
In this example,
$numberSet with some initial values.in_array function to check if an item exists in the set.in_array function returns true if the item is in the set, otherwise false.<?php
$numberSet = [1, 2, 3, 4, 5];
$containsThree = in_array(3, $numberSet);
echo 'Set contains 3: ' . ($containsThree ? 'true' : 'false') . "\n";
?>Set contains 3: true
