Some C/C++ coding standards make this even mandatory. But with PHP and some other web technologies, there are strong reasons to NOT have a newline at the end of the file, as it may result in undesired additional newline output to the client, possibly breaking everything.\r\n\r\nSmall example for illustration, including [LF] as newline ('\\n') and [EOF] as the end of the file.\r\n\r\noriginal file (old/test.php):\r\n```\r\n\u003c?php[LF]\r\n[LF]\r\necho \"\u003chtml\u003e\u003ctitle\u003easdf\u003c/title\u003e\u003cbody\u003easdf\u003c/body\u003e\u003c/html\u003e\";[LF]\r\n[LF]\r\n?\u003e[EOF]\r\n```\r\nwith patch file (without [LF] and [EOF], generated via `diff -Naur old/test.php new/test.php \u003e test.php.patch`):\r\n```\r\n--- old/test.php\t2017-03-29 11:19:36.103349100 +0200\r\n+++ new/test.php\t2017-03-29 11:20:16.270349100 +0200\r\n@@ -1,5 +1,5 @@\r\n \u003c?php\r\n \r\n-echo \"\u003chtml\u003e\u003ctitle\u003easdf\u003c/title\u003e\u003cbody\u003easdf\u003c/body\u003e\u003c/html\u003e\";\r\n+echo \"\u003chtml\u003e\u003ctitle\u003eA real title\u003c/title\u003e\u003cbody\u003eA real body\u003c/body\u003e\u003c/html\u003e\";\r\n \r\n ?\u003e\r\n\\ No newline at end of file\r\n\r\n```\r\nbecomes:\r\n```\r\n\u003c?php[LF]\r\n[LF]\r\necho \"\u003chtml\u003e\u003ctitle\u003eA real title\u003c/title\u003e\u003cbody\u003eA real body\u003c/body\u003e\u003c/html\u003e\";[LF]\r\n[LF]\r\n?\u003e[LF][EOF]\r\n```\r\n\r\nbut should be (new/test.php):\r\n```\r\n\u003c?php[LF]\r\n[LF]\r\necho \"\u003chtml\u003e\u003ctitle\u003eA real title\u003c/title\u003e\u003cbody\u003eA real body\u003c/body\u003e\u003c/html\u003e\";[LF]\r\n[LF]\r\n?\u003e[EOF]\r\n```\r\n","author":{"url":"https://github.com/nils-ballmann","@type":"Person","name":"nils-ballmann"},"datePublished":"2017-03-29T09:55:08.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/50/python-patch/issues/50"}
