What best practices should be followed when splitting and loading data into an array in PHP?

When splitting and loading data into an array in PHP, it is important to properly handle the data to ensure it is correctly formatted and stored in the array. One best practice is to use PHP's explode() function to split the data based on a delimiter, such as a comma or space. Additionally, it is important to validate the data before loading it into the array to prevent any potential errors or security vulnerabilities.

// Example of splitting and loading data into an array in PHP
$data = "John,Doe,Jane,Smith";
$delimiter = ",";
$dataArray = explode($delimiter, $data);

// Validate data before loading into array
if(!empty($dataArray)) {
    // Data is split and loaded into the array successfully
    print_r($dataArray);
} else {
    // Handle error if data is empty or not loaded correctly
    echo "Error loading data into array";
}
