How can PHP developers efficiently handle file parsing and data extraction for specific file formats in their code?

PHP developers can efficiently handle file parsing and data extraction for specific file formats by utilizing libraries or extensions that support the desired format. One common approach is to use PHP libraries like PHPExcel or PhpSpreadsheet for parsing Excel files, or libraries like SimpleXML or DOMDocument for parsing XML files. By leveraging these tools, developers can streamline the process of extracting data from various file formats in their PHP code.

// Example code using PhpSpreadsheet to parse an Excel file and extract data
require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\IOFactory;

$spreadsheet = IOFactory::load('example.xlsx');
$worksheet = $spreadsheet->getActiveSheet();

$data = [];
foreach ($worksheet->getRowIterator() as $row) {
    $rowData = [];
    foreach ($row->getCellIterator() as $cell) {
        $rowData[] = $cell->getValue();
    }
    $data[] = $rowData;
}

var_dump($data);
