PHP.NET | Magic Constants
__LINE__
The __LINE__ magic constant returns the value of the line the constant is placed on. For example, this line in the text editor is number 8, so the number 9 should appear below.
14__FILE__
The __FILE__ magic constant returns the complete file path from the server of the current file you are looking at.
/home/dh_u7w823/aallenprojects.me/wp-content/school-archives/php/research-documentation/02-phpnet.php__DIR__
The __DIR__ magic constant functions similarly to __FILE__, but returns the directory of the file instead. __DIR__ also takes into consideration the potential use of includes.
/home/dh_u7w823/aallenprojects.me/wp-content/school-archives/php/research-documentation__FUNCTION__
The __FUNCTION__ magic constant returns the name of the function if the constant is inside of a function. In this case, there is a __FUNCTION__ constant underneath this line in the text editor, but there it is not inside of a function.
