How can PHP developers handle the issue of empty delimiter warning while using explode() function for string manipulation?

When using the explode() function in PHP for string manipulation, developers may encounter a warning if an empty delimiter is passed as the second argument. To handle this issue, developers can check if the delimiter is empty before calling the explode() function to avoid the warning. 

// Check if the delimiter is empty before calling explode()
$delimiter = '';
$string = 'Hello World';
if (!empty($delimiter)) {
    $result = explode($delimiter, $string);
} else {
    $result = [$string];
}

// Output the result
print_r($result);
