What steps can be taken to troubleshoot and resolve issues with the "required" attribute not working in PHP scripts across different servers and browsers?

The issue with the "required" attribute not working in PHP scripts across different servers and browsers can be due to inconsistent server configurations or browser compatibility issues. To troubleshoot and resolve this problem, you can use PHP validation to check if the required fields are empty before processing the form data. 

// Check if the required fields are empty
if(empty($_POST['field1']) || empty($_POST['field2'])) {
    echo "Please fill out all required fields.";
} else {
    // Process the form data
}
