What are some common pitfalls when converting VBA code to PHP?

One common pitfall when converting VBA code to PHP is the difference in syntax and functions between the two languages. It is important to carefully review the VBA code and identify any VBA-specific functions or syntax that need to be replaced with their PHP equivalents. Additionally, VBA code often relies heavily on Microsoft Excel objects and methods, so it may be necessary to find alternative ways to achieve the same functionality in PHP.

// Example of replacing VBA-specific function (MsgBox) with PHP equivalent (echo)
// VBA code: MsgBox("Hello, world!")
// PHP code: echo "Hello, world!";
