php - unexpected T_STRING on first line of code -

i have been getting error saying unexpected t_string on line 2 of script:

<? php session_start(); $incidentkey = $_session['incidentkey']; $incidentdetailsquery = mysql_query("select * incidents incidentkey='".$incidentkey."'"); while ($incidentdetails = mysql_fetch_assoc($incidentdetailsquery); ?>

and despite looking through forum heaps, have had no luck. coming error saying unexpected t_string on line 2 when code started this:

<? php $incidentkey = $_session['incidentkey']; etc.....

i've gone through other includes , couldn't find missing terminators leading script. can think why else getting error?

remove space in

<? php

to create

<?php
