What is the recommended approach in PHP to search for values between commas in a string?

When searching for values between commas in a string in PHP, a recommended approach is to use the `explode()` function to split the string into an array based on the comma delimiter, and then loop through the array to find the desired values. Here is a PHP code snippet that demonstrates this approach: 

$string = "apple,banana,orange,grape";
$values = explode(",", $string);

foreach($values as $value) {
    echo $value . "\n";
}
