What common mistake is made when using the include function in PHP?

One common mistake made when using the include function in PHP is not providing the correct file path. This can result in the included file not being found or included properly. To solve this issue, always ensure that you provide the correct file path relative to the current file or use absolute paths for better accuracy.

// Incorrect include statement
include('myfile.php');

// Correct include statement with correct file path
include('path/to/myfile.php');
