-PHP can be used by embedding it in HTML. Write PHP instructions in <? Php ~?>, And the <? Php ~?> Part is converted to HTML and displayed.

・ Comments are made from “//” to the end of the line. Information that is not related to operation and is mainly used for memos.

・ Only when the number to be added is 1, it is possible to write in abbreviated form. Writing ++ before a variable adds it before the instruction on that line is executed, whereas writing ++ after a variable adds it after the instruction on that line is executed. The same is true for-for subtracting one.
