    This article written by our teacher can solve your problem: What are the changes in the global variable mechanism under PHP5 and PHP7 versions?

    The reason why different operation results appear is actually because in the latest php7 version, the PHP global variable processing mechanism has been modified. In this version, the global keyword can now only refer to simple variables.
