What potential issues can arise when transitioning a VB program with Excel macros to a PHP web technology?

One potential issue that can arise when transitioning a VB program with Excel macros to PHP web technology is the lack of direct support for Excel functionalities in PHP. To solve this issue, you can use a library like PHPExcel or PhpSpreadsheet to handle Excel operations in PHP. 

// Example using PhpSpreadsheet to read an Excel file
require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\IOFactory;

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

// Access cell value
$cellValue = $sheet->getCell('A1')->getValue();

echo $cellValue;
