what the mean of PHP_EOL

Question

I saw a code of PHP
there is $date.PHP.EOL
I just don't understand what is EOL

Answer 1

Think of PHP_EOL as a safer solution than using \n or \r for new line

It stands for end of line - it's platform independent so it's often recommended to use it instead of \n or when you want to reach the end of line

From the Web:
Use the php constant PHP_EOL to print the correct end of line symbol no matter what system you're on.

Example:
<?php
print "Hello World," . PHP_EOL . "I've missed you.";
?>

Hello World,
I've missed you.
