I am currently working on a project where I need to convert a date from the Gregorian calendar to the Jewish calendar using PHP. While researching, I came across the `jdtojewish()` function. However, I am not quite sure how to use it properly.
Could someone please provide me with an example of how to use the `jdtojewish()` function in PHP? It would be great if you could also explain the parameters and the expected output of the function.
I appreciate any help you can provide! Thank you in advance.
