[英]Read phar file from memory?
Is there a way that I can access a file from a phar without having to save the phar to disk first? 有没有一种方法可以从phar访问文件而不必先将phar保存到磁盘? In the following code, $fileContentsString
is the contents of a phar file that was loaded from the network. 在以下代码中, $fileContentsString
是从网络加载的phar文件的内容。 How can I take that string and read a file from it without having to save the string to disk as a file first? 如何获取该字符串并从中读取文件,而不必先将该字符串作为文件保存到磁盘? I've tried writing the string to php://temp
and then using Phar::loadPhar
to read it, but that fails. 我尝试将字符串写入php://temp
,然后使用Phar::loadPhar
读取它,但是失败了。
$tmpFilePath = TMP_PATH . '/' . $filename;
// Save the file to TMP_PATH
$fp = fopen($tmpFilePath, 'w');
fwrite($fp, $fileContentsString);
fclose($fp);
$contents = file_get_contents('phar://' . $tmpFilePath . '/json.txt');
php://temp
is a stream that can be used to store data in memory - but it can be only used via a file handle, not as a file system. php://temp
是可用于将数据存储在内存中的流-但只能通过文件句柄使用,而不能作为文件系统使用。 Opening another file handle on php://temp
will give you another part of the memory, and thus a new "file". 在php://temp
上打开另一个文件句柄将为您提供另一部分内存,从而获得一个新的“文件”。
You need a memory-only file system like PEAR's Stream_Var package which lets you access variables as a file system. 您需要一个仅内存的文件系统,例如PEAR的Stream_Var软件包 ,该软件包使您可以将变量作为文件系统进行访问。
