What potential issues could arise when running a PHP script on different servers?

One potential issue that could arise when running a PHP script on different servers is differences in server configurations, such as PHP versions or extensions installed. To solve this issue, you can use feature detection to check for the availability of certain functions or extensions before using them in your script. 

// Check if the function 'some_function' exists before calling it
if (function_exists('some_function')) {
    some_function();
} else {
    // Handle the case where the function is not available
    echo "Function 'some_function' is not available on this server.";
}
