Core Function BinaryWipe

BinaryWipe( <binary-array> )

Description

Wipes a binary variables data 100% and sets the variable to a blank int containing null.

Parameters

binary-array

The binary variable to wipe.

Return Value

Success: Returns 1.

Failure: Returns 0.

Remarks

This will only wipe this individual variable it will not wipe every variable containing a reference to this binary data.

What this means is its quite possible you will free no memory from using this unless you also wipe all other binary variables using this data.

Example

$binary = Pack("z0", "Hello World!\n" x 1000);
println( "Before Wipe: " . Unpack("z0", $binary) );
BinaryWipe($binary);
println( "After Wipe: " . $binary );

This is just as effective.

$binary = Pack("z0", "Hello World!\n" x 1000);
println( "Before Wipe: " . Unpack("z0", $binary) );
$binary = 0;
println( "After Wipe: " . $binary );

Also, this is just as effective.

$binary = Pack("z0", "Hello World!\n" x 1000);
println( "Before Wipe: " . Unpack("z0", $binary) );
unset($binary);
println( "After Wipe: " . $binary );
