How to give line break in php mail

In PHP, when sending an email using the mail() function or a mail library like PHPMailer, you can use the following methods to insert a line break:

1. Using \r\n:

   $message = "Hello,\r\nHow are you?";
   mail("[email protected]", "Subject", $message);

   The \r\n sequence is the standard way to insert a line break in plain text emails.

2. Using <br>:

   $message = "Hello,<br>How are you?";
   mail("[email protected]", "Subject", $message);

   The <br> tag is an HTML tag that represents a line break. However, keep in mind that this will only work if the email client is set to render HTML emails.

3. Using nl2br():

   $message = "Hello,\nHow are you?";
   $message = nl2br($message);
   mail("[email protected]", "Subject", $message);

   The nl2br() function converts all newline characters (\n) to HTML line breaks (<br>). This is useful if you want to preserve the original line breaks in your email content.

4. Using PHP_EOL:

   $message = "Hello,". PHP_EOL. "How are you?";
   mail("[email protected]", "Subject", $message);

   The PHP_EOL constant represents the end-of-line character for your operating system (e.g., \r\n on Windows, \n on Unix-like systems).

Remember to adjust the email content according to the email client and recipient's preferences. Some email clients may not render line breaks correctly, so it's always a good idea to test your email content before sending it.
