What are the recommended steps to troubleshoot and resolve issues with PHP code that involves reading and importing Excel files?

Issue: When reading and importing Excel files in PHP, it is important to ensure that the correct libraries are installed and configured properly. If there are issues with reading or importing Excel files, it is recommended to check the file path, permissions, and file format to ensure they are correct. 

// Check if the PHPExcel library is installed and configured properly
require_once 'PHPExcel/Classes/PHPExcel.php';

// Set the file path to the Excel file
$excelFile = 'path/to/excel/file.xlsx';

// Check if the file exists and is readable
if (file_exists($excelFile) && is_readable($excelFile)) {
    // Load the Excel file
    $objPHPExcel = PHPExcel_IOFactory::load($excelFile);

    // Get the active sheet
    $sheet = $objPHPExcel->getActiveSheet();

    // Loop through the rows to read and import data
    foreach ($sheet->getRowIterator() as $row) {
        $rowData = $row->getWorksheet()->rangeToArray('A' . $row->getRowIndex() . ':' . $sheet->getHighestDataColumn() . $row->getRowIndex(), null, true, false);
        
        // Process the data as needed
        // Example: echo $rowData[0][0];
    }
} else {
    echo 'Excel file does not exist or is not readable.';
}
