Mail () with textarea, needs to remove HTML tags

[phppaper]

I use mail() to build a mail system, the email contents from a textarea which able user to bold, underline or do other font editing. But through the mail(), the email content received did not edit the fonts, instead it shows up all those HTML tags, how can I remove the html tags show up in the email and still have the font effect?, example of a fail email:

 

<p>

testing</p>

<p>

 </p>

<p>

<strong><u>test</u></strong></p>

You need to send as a HTML email, rather than a text one. Im not sure how to do this exactly, but most mail classes (swiftmail, phpmailer, etc) have the option.
