多文件上传的表单陷阱
有时,我们为了方便上传多文件,在name的命名上,采用数组形式来命名
如pic[],pic[],pic[]
Array
(
[name] => Array
(
[0] => Winter.jpg
[1] => Water lilies.jpg
[2] => Blue hills.jpg
)
[type] => Array
(
[0] => image/jpeg
[1] => image/jpeg
[2] => image/jpeg
)
[tmp_name] => Array
(
[0] => D: mpphp709.tmp
[1] => D: mpphp70A.tmp
[2] => D: mpphp70B.tmp
)
[error] => Array
(
[0] => 0
[1] => 0
[2] => 0
)
[size] => Array
(
[0] => 105542
[1] => 83794
[2] => 28521
)
)
)
