PHP constant Php_eol

Line break

UNIX series with \ n

Windows series with \ r \ n

Mac with \ r

PHP can be replaced with Php_eol to improve code-level portability

Such as:

<?php
Echo Php_eol;
The Windows platform is equivalent to echo "\ r \ n";
Unix\linux platform equivalent to echo "\ n";
The Mac platform is equivalent to echo "\ r";


Similar to what is commonly used

Directory_separator

You can use the function get_defined_constants () to get all the PHP constants

<?php
Print_r (Get_defined_constants ());//get_defined_constants () returns all constant arrays
