Ibexa usage of PHP's supported versions calendar visualisation

Hi! We at Ibexa(1) might like to make use of PHP's supported versions calendar visualisation(2) and its source code(3) to illustrate Ibexa's own supported versions page(4). Now, looking at PHP's website copyright(5), that seems like it may not be allowed. However, considering that Symfony is using a very similar graphic(6) that they even attribute in source code to the PHP one, and that Ibexa DXP is mainly based on Symfony and PHP, might you be willing to allow it anyway? Hoping to hear from you!
