Why do some scripts omit the closing PHP tag, '?>'? [duplicate]
Solution 1:
Well, omitting the closing tag is just one solution for avoiding blanks and other characters at the end of file. For example any char which is accidentally added behind the closing tag would trigger an error when trying to modify header info later.
Removing the closing tag is kind of "good practice" referring to many coding guidelines.
Solution 2:
From PHP: Instruction Separation
The closing tag of a PHP block at the end of a file is optional, and in some cases omitting it is helpful when using
include()orrequire(), so unwanted whitespace will not occur at the end of files, and you will still be able to add headers to the response later. It is also handy if you use output buffering, and would not like to see added unwanted whitespace at the end of the parts generated by the included files.
