当上传多个文件时,PHP会对文件进行排序:
Array
(
[name] => Array
(
[0] => game-of-thrones-series-1080p-hd-wallpaper-movies.jpg
[1] => HD-Hitman-Wallpaper.jpg
[2] => New-Games-Wallpapers-Full-HD-1080p.jpg
)
[type] => Array
(
[0] => image/jpeg
[1] => image/jpeg
[2] => image/jpeg
)
[tmp_name] => Array
(
[0] => C:\xampp\tmp\php7659.tmp
[1] => C:\xampp\tmp\php765A.tmp
[2] => C:\xampp\tmp\php766A.tmp
)
[error] => Array
(
[0] => 0
[1] => 0
[2] => 0
)
[size] => Array
(
[0] => 579476
[1] => 1006801
[2] => 532174
)
)
我想先按文件编号对文件进行排序,如下所示:
Array
(
[0] => Array
(
[name] => game-of-thrones-series-1080p-hd-wallpaper-movies.jpg
[type] => image/jpeg
[tmp_name] => C:\xampp\tmp\php7659.tmp
[error] => 0
[size] => 579476
)
[1] => Array
(
[name] => HD-Hitman-Wallpaper.jpg
[type] => image/jpeg
[tmp_name] => C:\xampp\tmp\php765A.tmp
[error] => 0
[size] => 1006801
)
[2] => Array
(
[name] => New-Games-Wallpapers-Full-HD-1080p.jpg
[type] => image/jpeg
[tmp_name] => C:\xampp\tmp\php766A.tmp
[error] => 0
[size] => 532174
)
)
我知道可以通过使用foreach循环来完成,但我正在寻找一种更简单有效的方法。不知道怎么办呢?
