If nodejs (4.5/6.5) would be the environment, Buffer can partially achieve the functionality of unpack():

const buf = Buffer.from([0, 0, 0, 5]);
// Prints: 83886080
console.log(buf.readInt32LE());

See its documentation: https://nodejs.org/api/buffer.html#buffer_buf_readint32le_offset_noassert

This is equivalent to:

 unpack('V', join('', array_map(function ($a) { return chr($a); }, [0, 0, 0, 5])));
