Example
$binary = Pack("A*", "Hello World!"); BinaryReverse($binary); println( "Binary HEX: '" . BinaryStr($binary, ",") . "'" ); println("The binary size is: " . UBound($binary) ); Foreach ($binary as $i) { println( "Byte: " . $i . " | Hex: " . Hex($i) . " | Char: " . Chr($i) ); } $String = Unpack("A*", $binary, 3); println("Full string: " . $String);
Reverse everything after "He" example:
$binary = Pack("A*", "Hello World!"); BinaryReverse($binary, 2); println( "Binary HEX: '" . BinaryStr($binary, ",") . "'" ); println("The binary size is: " . UBound($binary) ); Foreach ($binary as $i) { println( "Byte: " . $i . " | Hex: " . Hex($i) . " | Char: " . Chr($i) ); } $String = Unpack("A*", $binary, 3); println("Full string: " . $String);
Reverse the "World" part example:
$binary = Pack("A*", "Hello World!"); BinaryReverse($binary, 6, 5); println( "Binary HEX: '" . BinaryStr($binary, ",") . "'" ); println("The binary size is: " . UBound($binary) ); Foreach ($binary as $i) { println( "Byte: " . $i . " | Hex: " . Hex($i) . " | Char: " . Chr($i) ); } $String = Unpack("A*", $binary, 3); println("Full string: " . $String);
