一个目录中每个文件的循环代码 [英] Loop code for each file in a directory

问题描述

我有一个我想循环的图片目录，并进行一些文件计算。它可能只是缺乏睡眠，但是我将如何使用PHP来查看给定的目录，并使用某种for循环遍历每个文件？

谢谢！

解决方案

scandir ：

  $ files = scandir（'folder /'）; 
 foreach（$ files as $ file）{
 //你的工作在这里
} 
  

或 glob 可能会更好地满足您的需求：

  $ files = glob（'folder / *。{jpg，png，gif}'，GLOB_BRACE）; 
 foreach（$ files as $ file）{
 //你的工作在这里
} 
  

I have a directory of pictures that I want to loop through and do some file calculations on. It might just be lack of sleep, but how would I use PHP to look in a given directory, and loop through each file using some sort of for loop?

Thanks!

解决方案

scandir:

$files = scandir('folder/');
foreach($files as $file) {
  //do your work here
}

or glob may be even better for your needs:

$files = glob('folder/*.{jpg,png,gif}', GLOB_BRACE);
foreach($files as $file) {
  //do your work here
}
