What are common issues that may cause PHP-generated content to display as #### in Excel?

When PHP-generated content displays as #### in Excel, it is typically due to the column width being too narrow to display the content properly. To solve this issue, you can adjust the column width in Excel to accommodate the content. 

// Set the content type header to Excel
header('Content-Type: application/vnd.ms-excel');
// Set the column width to auto-size
echo '<table><col width="auto">';
// Output your PHP-generated content here
echo '</table>';
