The php function error_log() let you send logs to email setting the second param to 1. I do that, but i want to dispay message in html. The code looks like this:
error_log($this->_errorMsg, 1, ADMIN_MAIL, "Content-Type: text/html; charset=utf8\r\nFrom: ".MAIL_ERR_FROM."\r\nTo: ".ADMIN_MAIL);
Probably i mess something declaring the content type, because i get msg in plain text:
<h1>Website Error</h1>
<b>ERRNO:</b><font color='red'>1</font>
