?>What does it mean?

Question

Every time I see the code saying ?>, what does it mean? Does it mean that the above code has been written?

Answer 1

It must be written when nested in html. But in pure PHP, such as controllers, it is better not to write anything. Even if you have to write it, don’t leave a space at the end of ?>. Otherwise, an error may be reported

Answer 2

If it is a php file, you can omit the end character. When inserting it into html, you need to write all

Answer 3

<?php //Start character

?>//End character
