<?php
if($_GET[’action’] == ’upfile’)
{
$target_path = ’temp_’.$_FILES[’photo’][’name’];
echo ’上传的临时文件：’ .$_FILES[’photo’][’tmp_name’] . ’<br/>’;
echo ’上传的目标文件：’ .$target_path . ’<br/>’;
echo $_SERVER["SCRIPT_FILENAME"] . ’<br/>’;
echo $_SERVER["OS"] . ’<br/>’;
//测试函数: move_uploaded_file
//也可以用函数：copy
move_uploaded_file($_FILES[’photo’][’tmp_name’], $target_path);
echo "Upload result:";
if(file_exists($target_path)) {
if($_SERVER["OS"]!="Windows_NT"){
@chmod($target_path,0604);
}
echo ’<font color="green">Succeed!</font><br /><a href="http://’ .$_SERVER["SERVER_NAME"] . "/" .$target_path .’"><img src=’ .$target_path .’ border="0">’;
} else {
echo ’<font color="red">Failed!</font>’;
}
exit;
}
