Need help fixing some PHP error

Can you please tell me what I need to do to fix this error. I have tried removing the initial php tag but got a worse error.
Parse error: syntax error, unexpected ‘<‘ in /home/mary/public_html/mary-content/plugins/insert-php/insert_php.php(48) : eval()’d code on line 1

just fyi there is another error, the same as the first but with syntax error, unexpected ‘&’ in /home/mary/public_html/mary-content/plugins/insert-php/insert_php.php(48)
