What are the differences between fetching the content and body of an email in PHP?

When fetching the content of an email in PHP, you are retrieving the entire email including headers, attachments, and any other metadata. On the other hand, when fetching the body of an email, you are specifically retrieving the main text or HTML content of the email without any additional information. To fetch the content of an email in PHP, you can use the imap_fetchbody function with the FT_UID flag to retrieve the entire email content. On the other hand, to fetch just the body of an email, you can use the imap_fetchbody function with the FT_UID flag and specify the body part number (usually 1 for the main text or 2 for HTML content).

// Fetching the content of an email
$emailContent = imap_fetchbody($inbox, $emailNumber, "", FT_UID);

// Fetching the body of an email
$emailBody = imap_fetchbody($inbox, $emailNumber, "1", FT_UID);
