Can't we use mail as variable in wordpress

In WordPress, the mail() function is not directly accessible as a variable, but you can use the wp_mail() function instead.

wp_mail() is a WordPress function that allows you to send emails using the WordPress mail system. It's a wrapper around the PHP mail() function, but it provides more features and flexibility.

Here's an example of how you can use wp_mail() to send an email:

wp_mail( '[email protected]', 'Subject', 'Hello, this is a test email!' );

In this example, wp_mail() takes three arguments:

1. recipient: The email address of the recipient.
2. subject: The subject of the email.
3. message: The body of the email.

You can also pass additional arguments to wp_mail() to customize the email, such as:

• headers: An array of headers to add to the email.
• attachments: An array of file paths or URLs to attach to the email.
• from: The email address of the sender.

Here's an example of how you can use wp_mail() with additional arguments:

wp_mail( '[email protected]', 'Subject', 'Hello, this is a test email!', array(
    'From' => '[email protected]',
    'Content-Type' => 'text/plain',
), array( 'file1.txt', 'file2.pdf' ) );

In this example, we're setting the From header to [email protected], the Content-Type header to text/plain, and attaching two files (file1.txt and file2.pdf) to the email.

So, to answer your question, while you can't use the mail() function directly as a variable in WordPress, you can use the wp_mail() function to send emails with more flexibility and control.
