email - Which line break in php mail header, or ?

I've seen a lot of examples using the php mail function. Some of them use as line break for the header, some use .

$headers = "From: Just Me
"; 
$headers .= "Reply-To:  Just me <$email>
"; 

vs

$headers = "From: Just Me
";
$headers .= "Reply-To:  Just me <$email>
";

which one is correct?

Sometimes I've had cases where is used and part of the header is interpreted by some email clients as mail text (losing these header information) - is this because is wrong?

The CRLF , should be used according to the php documentation. Also, to conform to the RFC 2822 spec lines must be delimited by the carriage return character, CR immediately followed by the line feed, LF .

Since is native to Windows platforms and to Unix, you can use the PHP_EOL­Docs constant on Windows, which is the appropriate new line character for the platform the script is currently running on.
