Are there any best practices to follow when using explode in PHP for data extraction?

When using the explode function in PHP for data extraction, it is important to follow best practices to ensure accurate and efficient extraction of data. One common best practice is to check if the delimiter exists in the input string before using explode to avoid errors. Additionally, it is recommended to trim the input string and handle any potential empty values or whitespace after exploding the string. 

$input_string = "apple,banana,orange";
$delimiter = ",";
if (strpos($input_string, $delimiter) !== false) {
    $data = explode($delimiter, $input_string);
    $data = array_map('trim', $data);
    // Handle extracted data here
} else {
    // Handle case when delimiter is not found in input string
}
