How can PHP developers efficiently troubleshoot and debug CSV export issues like missing data or formatting errors?

To efficiently troubleshoot and debug CSV export issues like missing data or formatting errors, PHP developers can use tools like var_dump() or print_r() to inspect the data being exported, check for any empty fields or incorrect formatting, and ensure that the data is properly formatted before exporting it to a CSV file. 

// Example code snippet to troubleshoot and debug CSV export issues
$data = array(
    array('Name', 'Age', 'Email'),
    array('John Doe', 30, 'johndoe@example.com'),
    array('Jane Smith', '', 'janesmith@example.com'),
);

// Check for missing data
foreach ($data as $row) {
    if (in_array('', $row)) {
        echo "Missing data found in row: " . implode(', ', $row) . "\n";
    }
}

// Check data formatting
foreach ($data as $row) {
    foreach ($row as $value) {
        if (!is_string($value) && !is_numeric($value)) {
            echo "Incorrect data formatting found: " . $value . "\n";
        }
    }
}

// Export data to CSV file
$fp = fopen('export.csv', 'w');
foreach ($data as $row) {
    fputcsv($fp, $row);
}
fclose($fp);

echo "CSV export completed successfully";
