model a sequence of data elements made available over time

Usage

Write and read (or peek) from a string of characters.

$stream = new \WillWashburn\Stream\Stream();
$stream->write('foo');

$stream->read(3); //foo

$stream->write('bar');
$stream->write('bang');

$stream->read(4); // barb
$stream->peek(3); // ang
$stream->read(3); // ang

I mostly use this when buffering responses from curl requests.

$stream = new WillWashburn\Stream\Stream;

curl_setopt($ch, CURLOPT_WRITEFUNCTION, function ($ch, $str) use (& $stream, $url) {
           
   $stream->write($str);
   
   try {
       // do something with the stream
       $characters = $stream->read(100);
       
       // tell curl to stop the transfer when we find what we're looking for
       if(strpos($characters,'string im looking for') !==false) {
           return -1;
       }
   }
   catch (StreamBufferTooSmallException $e) {
       // The buffer ended, so keep getting more
       return strlen($str);
   }
   
   //  We return -1 to abort the transfer when we have enough buffered
   return -1;
});
