在php中发送邮件时出错

I am using the mail function of php to send the mail so for i am calling the function like

mail($EMAIL_HOST_USER, "Invitation for conference ", $message);

but i am getting an unexpected error

<br />
<b>Parse error</b>:  syntax error, unexpected 'mail' (T_STRING) in <b>/opt/lampp/htdocs/UI/user/usernotify.php</b> on line <b>43</b><br />

i am not sure where i am doing wrong .

Any help would be appreciated

You have a syntax error on some line above the line you show - most likely you forgot a semi-colon or something like that.
