How can developers optimize the process of resizing strings to fit within cell widths in PHP PDF generation libraries?

When generating PDFs in PHP, developers often need to resize strings to fit within cell widths to ensure proper formatting. One way to optimize this process is to calculate the width of the string using the PDF library's built-in functions and adjust the font size accordingly. This ensures that the text fits within the designated cell width without being cut off or overflowing. 

// Calculate the width of the string using the PDF library's built-in functions
$text = "Lorem ipsum dolor sit amet";
$font_size = 12; // initial font size
$cell_width = 100; // width of the cell
$text_width = PDFLib::getTextWidth($text, $font_size);

// Adjust the font size to fit within the cell width
while ($text_width > $cell_width) {
    $font_size--; // decrease font size
    $text_width = PDFLib::getTextWidth($text, $font_size);
}

// Output the text with the adjusted font size
PDFLib::drawText($text, $font_size);
