我可以在php脚本中合并2个（或者更多）php函数吗？

Question

im a begginer. is it possible to put two functions in one php script?, per example:

having a php script loading a xml file (simplexml_load_file) and then after I've got the data i want to from that xml also put the DomDocument functions(and variables and all that) to create another xml and write the data parsed(to just the data i want,or maybe convert the data to json format. Question1:is it possible? Question2: or do i need to run those functions in separate scripts with exec();function ?

any explicit explanation is appreciated or link to learn about it. -Thanks.

Answer 1

You can call any number of functions in your one script file.
