You can use the box-tracking API.

Here is an example of using it to detect overflow:

hey mike,

Is there any example of box tracking API for php prince xml.

The use of this API all happens within JavaScript, but it could log some output messages for the PHP to check if necessary. What is it you want to do if the boxes are on the same page / different pages?

yes, i want to detect if boxes are on same / different pages before conversion

how to use JavaScript in php princexml. I have added my JS file by below code

$prince = new Prince('usr/bin/prince');
$prince->addScript(__DIR__ . '/../../public/js/main.js');

Any code written in my JS file is not reflecting in pdf.

Please suggest asap

Are you seeing any errors in the Prince output log? Does the script work when you run Prince from the command-line?
