My previous environment is PHP5.2.8 IIS is mounted in ISAPI manner, and now I replaced PHP5.3.14 is iis+fastcgi way to mount, the result is tragic before this program can be run, but now can't run
function Kc_f_singleupload ($id, $path, $filetype =0, $count =1, $width =1000, $height =1000) {
Global $king;
$s. = "";
$s. =kc_icon (' A9 ', $king->lang->get (' System/common/singleupload ')). $king->lang->get (' system/common/ Singleupload ');
$s. = "";
$s. = "trim";
$s. = '
';
return $s;
}

Hint $s.= ""; error, please help to see what is going on, thank you ...

Is it related to the way PHP is loaded? I feel that it should be related to the configuration of PHP, you have to restore the original PHP configuration file to the present look

Just post your error message.
