Are there conventions to indicate a new item in a list? WebIf by array of bytes you mean: $bytes = array (255, 0, 55, 42, 17, ); array_map () Then it's as simple as: $string = implode (array_map ("chr", $bytes)); foreach () Which is the compact version of: $string = ""; foreach ($bytes as $chr) { $string .= chr ($chr); } // Might be a bit speedier due to not constructing a temporary array. C# Note: A robust implementation of the String to ArrayBuffer conversion capable of handling more encodings is provided by the stringencoding library. Base64, by design, expects binary data as its input.

Convert a byte array to a hexadecimal string. Returns false otherwise. This isn't to say that split() doesn't work well with Regular Expressions - but it is to say that splitting sentences out of text isn't solved well by split(). New bytes are initialized to 0. Input is a byte array composed of ordered fields using zero byte (0x00) as a separator. These properties are defined on ArrayBuffer.prototype and shared by all ArrayBuffer instances. > TLDR: If you are new to algorithms and data structures, I highly recommend The major benefit of using Array.from() instead of split() is that you don't have to bother with setting a delimiter - the constituent elements are just re-exposed and added to an array, rather than being converted explicitly.
