To get the size of a temp stream in PHP, you can use the fstat() function along with the ftell() function. Here's an example:

$tmpStream = tmpfile();  // Create a temporary stream

// Write some data to the stream
fwrite($tmpStream, "Hello, World!");
fwrite($tmpStream, "This is a test.");

// Get the current position within the stream
$position = ftell($tmpStream);

// Seek to the start of the stream
rewind($tmpStream);

// Get the file statistics using fstat()
$fileStats = fstat($tmpStream);

// Get the size of the stream using the file size from the stats and the position
$streamSize = $fileStats['size'] - $position;

// Output the size of the stream
echo "Size of the temp stream: " . $streamSize . " bytes";

// Close the temporary stream to clean up
fclose($tmpStream);


In this example, we first create a temporary stream using tmpfile() and write some data to it using fwrite(). We then get the current position within the stream using ftell(), seek back to the start of the stream using rewind(), and then get the file statistics using fstat(). Finally, we calculate the size of the stream by subtracting the position from the file size obtained from the stats.
