文件操作的问题

Jun 23, 2016 pm 02:22 PM

我想做个图片墙,有以下问题,想请教:
1.请问linux文件名支持'-'(中杠)吗?
2.图片墙可以分页显示吗?类似于操作数据库那样,但操作文件名,怎么分页显示呢?


回复讨论(解决方案)

1.一般不要用这个吧,下划线不行么?
2.可以,没做过,但见过分页的。你可以想想,图片墙也不可能把图片无限显示,例如上千张?到一定的条件就判断为结束,这个条件可以作为分页依据

1、支持
2、可以,很多第三方的库,主要都是JS的

1、可以
2、可以,图片墙一般使用瀑布流,当然分页也可以
但获取文件列表只能是全部的,规划的好时,可以按子目录读取
一般用 glob 函数取文件列表到数组,再从上次最后输出的位置继续输出

我是想先循环读取,然后用类似数据库LIMT那样,20-50的话,循环到20开始显示图片,一直到50,这样可以吗?

$a = glob('目录/*');
foreach(array_slice($a, 20, 30) as $f) {
  echo $f;
}
