Save file with file_put_contents in folder
提问by James Bedret
file_put_contents('image.jpg',file_get_contents('http://static.adzerk.net/Advertisers/12f0cc69cd9742faa9c8ee0f7b0d210e.jpg'));
Saving the file in current folder is working ok, but if I try
将文件保存在当前文件夹中可以正常工作，但是如果我尝试
file_put_contents('/subfolder/image.jpg',file_get_contents('http://static.adzerk.net/Advertisers/12f0cc69cd9742faa9c8ee0f7b0d210e.jpg'));
I have an error:
我有一个错误：
failed to open stream: No such file or directory in […]
无法打开流：[...] 中没有这样的文件或目录
Why does this error occur? How can I save the file in a subfolder?
为什么会出现这个错误？如何将文件保存在子文件夹中？

Always use full paths and make sure the directory is writable. You can also use copydirectly with URL
始终使用完整路径并确保目录可写。您也可以copy直接使用 URL
$url = 'http://static.adzerk.net/Advertisers/12f0cc69cd9742faa9c8ee0f7b0d210e.jpg';
$dir = __DIR__ . "/subfolder"; // Full Path
$name = 'image.jpg';
is_dir($dir) || @mkdir($dir) || die("Can't Create folder");
copy($url, $dir . DIRECTORY_SEPARATOR . $name);

Try to leave out the first slash:
尝试省略第一个斜杠：
file_put_contents('subfolder/image.jpg',file_get_contents('http://static.adzerk.net/Advertisers/12f0cc69cd9742faa9c8ee0f7b0d210e.jpg'));
Check the access rights if this still doesn't work.
如果这仍然不起作用，请检查访问权限。

You should check if folder exsits and if not create this folder
您应该检查文件夹是否存在，如果不存在则创建此文件夹
$dir_to_save = "/subfolder/";
if (!is_dir($dir_to_save)) {
mkdir($dir_to_save);
}
file_put_contents($dir_to_save.'image.jpg',file_get_contents('http://static.adzerk.net/Advertisers/12f0cc69cd9742faa9c8ee0f7b0d210e.jpg'));
also make sure that you want to use ABSOLUTE_PATHinstead of RELATIVE
还要确保您要使用ABSOLUTE_PATH而不是RELATIVE

file_put_contents('../subfolder/image.jpg',file_get_contents('http://static.adzerk.net/Advertisers/12f0cc69cd9742faa9c8ee0f7b0d210e.jpg'));
add "../" in your string put into the file_put_contents function then it will work fine..回答by Devanshu Goyal
$dir = "folder_name".$filename;
you can use the above to simply put contents to any file of any folder.
您可以使用上述内容简单地将内容放入任何文件夹的任何文件中。

my problem was caused by folder permissions.
when I created my subfolder, the rootwas the owner,
since my php runs with the apacheuser, I needed to update the owner of the folder to be apache.
我的问题是由文件夹权限引起的。当我创建我的子文件夹时，它root是所有者，因为我的 php 与apache用户一起运行，我需要将文件夹的所有者更新为apache.

You must use backslashes:
您必须使用反斜杠：
file_put_contents('images\'.$filename, base64_decode($imgBase64));
or
或者
file_put_contents('K:\Site\images\'.$filename, base64_decode($imgBase64));
