How can the explode function be utilized in PHP to separate names from a string?

To separate names from a string in PHP, you can use the explode function to split the string into an array based on a specific delimiter, such as a space or comma. This allows you to access each individual name separately for further processing or manipulation.

$string = "John Doe, Jane Smith, Alice Johnson";
$names = explode(", ", $string);

foreach ($names as $name) {
    echo $name . "<br>";
}
