How can you ensure that all array contents are properly displayed when using a foreach loop in PHP?

When using a foreach loop in PHP to iterate over an array, it is important to ensure that all array contents are properly displayed. One common issue is that if the array contains HTML or special characters, they may not be displayed correctly due to escaping. To solve this issue, you can use the htmlspecialchars function to properly encode the array values before displaying them. 

<?php
$array = ['<b>Apple</b>', 'Orange', 'Banana'];

foreach ($array as $value) {
    echo htmlspecialchars($value) . "<br>";
}
?>
