Contents |
Description
Create a binary array from a hex string.
Parameters
expression
A string of hex to convert into a binary variable.
flag
Optional; There are a few flags that can be turned on or off using the | operator
1 = The string actually is hex using \x escape and is to be treated as such
2 = Add a zero to the end of the binary data (null termination)
(To make that flag has null termination and uses a \x string you would do 1 | 2)
Return Value
Success: Returns the binary variable.
Failure: Returns null.
Remarks
The string must contain only the hex chars nothing else not even 0x or spaces.
Example
$binary = BinaryHex("48656c6c6f20576f726c6421"); println( "Binary HEX: '" . BinaryStr($binary, ",") . "'" ); println("The binary size is: " . BinaryLen($binary) ); Foreach ($binary as $i) { println( "Byte: " . $i . " | Hex: " . Hex($i) . " | Char: " . Chr($i) ); } $String = Unpack("A*", $binary, 3); println("Full string: " . $String);
Example of using the flag
$binary = BinaryHex("\x48\x65\x6c\x6c\x6f\x20\x57\x6f\x72\x6c\x64\x21", true); println( "Binary HEX: '" . BinaryStr($binary, ",") . "'" ); println("The binary size is: " . BinaryLen($binary) ); Foreach ($binary as $i) { println( "Byte: " . $i . " | Hex: " . Hex($i) . " | Char: " . Chr($i) ); } $String = Unpack("A*", $binary, 3); println("Full string: " . $String);
