How can the explode function in PHP be utilized to separate keywords from a comma-separated list?

To separate keywords from a comma-separated list in PHP, you can use the explode function. This function splits a string into an array based on a specified delimiter, in this case, a comma. Once the string is split into an array, you can access each keyword individually for further processing. 

$keywords = "apple, banana, orange";
$keyword_array = explode(", ", $keywords);

foreach($keyword_array as $keyword){
    echo $keyword . "<br>";
}
