How can you efficiently loop through and display all selected checkboxes in PHP without overwriting the values?

When looping through and displaying all selected checkboxes in PHP without overwriting the values, you can achieve this by using an associative array to store the values of the checkboxes. This way, you can maintain the selected values without overwriting them during the loop. 

// Initialize an empty associative array to store the selected checkbox values
$selectedCheckboxes = [];

// Loop through all checkbox values
foreach ($_POST['checkbox'] as $checkbox) {
    // Store the selected checkbox values in the associative array
    $selectedCheckboxes[] = $checkbox;
}

// Display the selected checkbox values
foreach ($selectedCheckboxes as $checkbox) {
    echo $checkbox . "<br>";
}
