Size

The Stream components offer a few ways to determine the size of the underlying resource.

• Raw size
• Count
• Formatted Size

Raw size

Use getSize() to obtain the stream's size in bytes. The method returns null if the size is not known or cannot be determined.

// E.g. open file that 128 bytes in size
$stream = FileStream::open('persons.txt', 'r');

echo $stream->getSize(); // 128

Count

The Stream components inherit from PHP's Countable interface. This allows you to use count() directly on the stream.

// E.g. open file that 51 bytes in size
$stream = FileStream::open('places.txt', 'r');

echo count($stream); // 51

Formatted Size

Use getFormattedSize() if you wish to obtain a "human-readable" size of the stream.

The method returns a formatted string.

// E.g. open a "large" file...
$stream = FileStream::open('fx_lightning.mp4', 'r');

echo $stream->getFormattedSize(); // 4.3 MB
