What potential issues can arise when using number_format in PHP for formatting values in a PDF table?

When using number_format in PHP for formatting values in a PDF table, potential issues can arise with the alignment of the numbers. This is because number_format adds commas as thousands separators, which can disrupt the alignment of the columns in the table. To solve this issue, you can use str_replace to remove the commas before outputting the formatted number in the PDF table.

// Sample value to format
$value = 1000;

// Format the value with number_format
$formatted_value = number_format($value);

// Remove commas for proper alignment in PDF table
$formatted_value = str_replace(',', '', $formatted_value);

// Output the formatted value in the PDF table
echo $formatted_value;
