How can working with the PDF tree structure improve text extraction in PHP?

When extracting text from a PDF in PHP, working with the PDF tree structure can improve the accuracy and efficiency of the text extraction process. By navigating through the tree structure of the PDF document, you can access the text elements in a structured manner, making it easier to extract and manipulate the text content. 

// Load the PDF file
$pdf = new \Smalot\PdfParser\Parser();
$pdf = $pdf->parseFile('example.pdf');

// Get the pages from the PDF
$pages = $pdf->getPages();

// Loop through each page and extract text
foreach ($pages as $page) {
    $text = $page->getText();
    
    // Process the extracted text as needed
    echo $text;
}
