BinaryToStr( <binary-array> )

Contents

Description

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

Parameters

binary-array

The binary variable to use.

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

$binary = Pack("z0iii", "Hello World!", 100, 200, 300);
echo "First binary variable printed BELOW\n";
printr($binary);
echo "First binary variable printed ABOVE\n";
$binStr = BinaryToStr($binary);
echo "String Content: $binStr\n";
echo "Second binary variable printed BELOW\n";
printr(BinaryFromStr($binStr));
echo "Second binary variable printed ABOVE\n";
/*
Prints:
First binary variable printed BELOW
{BINARY:24}
