BinaryClone( <binary-array> )
Contents |
Description
Clone a binary variable 100% and return a new binary variable with exactly same data as the old one.
Parameters
binary-array
The binary variable to use.
Return Value
Success: Returns 1.
Failure: Returns 0.
Remarks
Contrary to what you might think simply doing
$binary2 = $binary1
That does not *copy* the data it will simply creates a reference to it making a change at either variable will change both so if you wish to actually copy a binary variables data you will need to use BinaryClone or BinaryMid etc.
Example
$binary = Pack("z0", "Hello World!"); $binary2 = BinaryClone($binary); BinaryReverse($binary); println("b1: " . Unpack("z0", $binary)); println("b2: " . Unpack("z0", $binary2));
