<p>This can be potentially dangerous since the exact format for the binary data can
differ depending on convention and system. The advantage is that it usually gives
smaller data files and is usually not as suspect to data corruption since it is not
easy to read directly into a text editor and change. In PHP a variable can be stored
in a binary format using the <codeclass="code">serialize()</code> function and read back from a
file with <codeclass="code">unserialize()</code></p>
