Question

Answer 1

A:

To be honest, I'm unsure what you mean by binary array (GIS didnt clarify either). If you mean a c-style array with one character-per-element, then you want the str_split built-in.

Answer 2

A:

There is no such thing as a binary array in php. All functions requiring byte streams operate on strings. What is it exactly that you want to do?

Answer 3

+1 A:

If you're trying to access a specific part of a string you can treat it like an array as-is.

$foo = 'bar';
echo $foo[0];

output: b

For this kind of string access, I believe curly brace notation is preferable (otherwise you risk confusing the hell out of anyone else maintaining your code). For example: $foo{0}

Unless I'm mistaken, Curly brace notation for this is deprecated in PHP 6

Ah, here it is: http://us.php.net/language.types.stringThe "Note" under the heading - "String access and modification by character"

Answer 4

+1 A:

I think what you are asking for is the equivalent to the perl pack/unpack functions. If that is the case, I suggest you look at the PHP pack/unpack functions:

Unpack
Pack

This is exactly what I was looking for.
