<script>ec(2);</script>
程序如下：
＄file_name = "info_check.exe";
＄file_dir = "/public/www/download/";
if (!file_exists(＄file_dir . ＄file_name)) { //检查文件是否存在
echo "文件找不到";
exit;
} else {
＄file = fopen(＄file_dir . ＄file_name,"r"); //打开文件
//输入文件标签
Header("Content-type: application/octet-stream");
Header("Accept-Ranges: bytes");
Header("Accept-Length: ".filesize(＄file_dir . ＄file_name));
Header("Content-Disposition: attachment; filename=" . ＄file_name);
//输出文件内容
echo fread(＄file,filesize(＄file_dir . ＄file_name));
fclose(＄file);
exit;}
而如果文件路径是"http"或者"ftp"网址的话，则源代码会有少许改变，程序如下：
＄file_name = "info_check.exe";
＄file_dir = "www.easycn.net/";
＄file = @ fopen(＄file_dir . ＄file_name,"r");
if (!＄file) {
echo "文件找不到";
} else {
Header("Content-type: application/octet-stream");
Header("Content-Disposition: attachment; filename=" . ＄file_name);
while (!feof (＄file)) {
echo fread(＄file,50000);
}
fclose (＄file);
}
这样就可以用PHP直接输出文件了
