Core Function BinaryToStr

BinaryToStr( <binary-array>, <flag>, <start>, <length> )

Description

Returns a new string containing the binary data as raw bytes.

Parameters

binary-array

The binary variable to use.

flag

Optional; Encoding to use.

Choices are:

"RAW" = Forces each byte in the binary to directly become a character in the string

"UNICODE" = Alias to UTF8 (or whatever Sputnik is using for Unicode strings)

"ASCII"

"UTF8"

"UTF7"

"UTF32"

Default: "RAW"

Return Value

Returns a new string containing the binary data as raw bytes.

Remarks

Sputnik strings allow null terminators inside them so they can be used just like raw binary data this is useful since you can treat it as a string and use all the string functions but yet it's also binary.

Example

ASCII Example

$binary = Pack("A*", "Hello World!");
$binStr = BinaryToStr($binary);
echo "String Content: $binStr\n";
// Prints:
// String Content: Hello World!

UNICODE (UTF8) Example

$binary = BinaryFromStr("ふふふ", "UTF8");
printr $binary;
$binStr = BinaryToStr($binary, "UTF8");
echo "String Content: $binStr\n";
// Prints:
// String Content: ふふふ

Using start parameter to get everything starting with World

$binary = BinaryFromStr("Hello World!", "ASCII");
$binStr = BinaryToStr($binary, "ASCII", 6);
echo "String Content: $binStr\n";
// Prints:
// String Content: World!

Using start and length parameter to get just World

$binary = BinaryFromStr("Hello World!", "ASCII");
$binStr = BinaryToStr($binary, "ASCII", 6, 5);
echo "String Content: $binStr\n";
// Prints:
// String Content: World
