What are common challenges when using PHP to open pop-up windows with specific attributes?

When using PHP to open pop-up windows with specific attributes, common challenges include ensuring that the pop-up window is not blocked by the browser's pop-up blocker, setting the desired window size and position, and passing data from the parent window to the pop-up. To address these challenges, you can use JavaScript within the PHP code to open the pop-up window with the desired attributes. 

<?php
echo '<script type="text/javascript">
        var newWindow = window.open("popup.html", "_blank", "width=400, height=400, top=100, left=100");
        newWindow.onload = function() {
            newWindow.document.getElementById("data").innerHTML = "Data passed from parent window";
        };
      </script>';
?>
