Issue: PHP beginners can improve their understanding of basic programming concepts by practicing data conversion between systems. One way to troubleshoot issues related to data conversion is to make sure to use the correct data types and conversion functions when transferring data between different systems. Code snippet:

// Example of converting data from one system to another
$data_from_system1 = "123"; // Data from System 1
$data_to_system2 = (int) $data_from_system1; // Convert data to integer for System 2

// Display the converted data
echo $data_to_system2;
