Is string in mail format function php

In PHP, the mail() function is used to send an email. The first argument to the mail() function is the recipient's email address, and the second argument is the subject of the email.

The third argument is the message body of the email, which can be a string. This string can contain HTML code, but it's not recommended to use HTML code in the message body directly. Instead, you can use the wordwrap() function to wrap the text and then use the nl2br() function to convert newline characters to HTML <br> tags.

Here's an example of how you can use the mail() function with a string message body:

$to = '[email protected]';
$subject = 'Test email';
$message = 'This is a test email sent using PHP.';

mail($to, $subject, $message);

However, if you want to send an email with a formatted message body, such as HTML or plain text, you can use the mime_content_type() function to specify the content type of the message body.

Here's an example of how you can use the mail() function with a formatted message body:

$to = '[email protected]';
$subject = 'Test email';
$message = '<html><body>This is a test email sent using PHP.</body></html>';
$headers = 'MIME-Version: 1.0'. "\r\n";
$headers.= 'Content-Type: text/html; charset=UTF-8'. "\r\n";

mail($to, $subject, $message, $headers);

In this example, the message body is an HTML string that contains an <html> and <body> tag. The headers variable is used to specify the content type of the message body as text/html.
