Memory streams View as Markdown

I'm new to this list, so I aplogize if this is not the place to
post this message.

It fits the php-general list better perhaps.

In this way, all functions requiring a file could be used on a memory
buffer.

You mean like this:

Hello,

I'm new to this list, so I aplogize if this is not the place to
post this message.

I was using today the getimagesize() function which takes a file
name. I was trying to take the size of an image decoded using
base64_decode from a string. So I have my decoded data in $data.
Now to apply getimagesize() I need a file, so I saved $data to
a temporary file and everything worked. I then tried to avoid
the temporary file by using i/o streams, but I didn't manage to
do this.

Correct me if I am wrong, but from what I see there is no way
to create a memory stream using php://memory and also attach
a unique key to it. If that would be possible, I could create
a memory stream with a unique key, write the data into it and
then pass this memory stream name to the getimagesize() function.

In this way, all functions requiring a file could be used on
a memory buffer.

You could implement your own stream with stream_wrapper_register(), and
then use URLs like "mycustomstream://12345678", and your stream
implementation could then extract the "12345678" part to use as a key,
for example.
