jqmodal, trying to display modal on click with text from php file

First time user of jqmodal here and I am trying to display a 开发者_运维技巧modal when I click a button. However, the text that I want to put on the modal is in a php file, which is in the href attribute. How can I get the information in the php file to the modal when I click this button?

I am completely lost here, any help would be great.

Let's say:

 .json (button) 

 /folder/file.php (php file)

Thank you for your help!
