文件上传的时候指定路径中的./和/和../的区别
文件上传的路径是相对于服务器的根目录还是相对于文件上传scirpt而言的。
另外上传路径有时候
<code>uploads/ /uploads/ ./uploads/ ../uploads/ </code>
这几个究竟有什么区别呀。彻底要被路径搞混了。

假设script所在路径：/data/www/project/script
目录结构：
<code>/
data/
www/
uploads/ ①
project/
uploads/ ②
script
uploads/ ③</code>那么：
uploads/ 是②
/uploads/ 是③
./uploads/ 是②
../uploads/ 是①
<code>uploads/ ==》当前路径平级的uploads目录 /uploads/==》当前路径根目录下的uploads目录 ./uploads/==》当前路径前1级目录下的uploads目录 ../uploads/==》当前路径前2级目录下的uploads目录</code>
楼上正确，我习惯是尽量用/打头写相对根路径
我觉得你打印输出一下就会得到答案。。。
