What are some best practices for searching for a specific value in a CSV file using PHP?

When searching for a specific value in a CSV file using PHP, it is important to read the file line by line and check each line for the desired value. One approach is to use the fgetcsv() function to parse each line as an array and then search for the value within that array. Another approach is to use the SplFileObject class to iterate through the CSV file and search for the value in each row. 

$csvFile = 'example.csv';
$searchValue = 'desired_value';

if (($handle = fopen($csvFile, 'r')) !== false) {
    while (($data = fgetcsv($handle)) !== false) {
        if (in_array($searchValue, $data)) {
            echo 'Value found in CSV file.';
            break;
        }
    }
    fclose($handle);
}
