BinaryHex( <expression>, <flag> )
Contents |
Description
Create a binary array from a hex string.
Parameters
expression
A string of hex to convert into a binary variable.
flag
Optional; True if the string actually is hex using \x escape or False if the string is just hex digits in text
Return Value
Success: Returns the binary variable.
Failure: Returns 0.
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("z0", $binary); 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("z0", $binary); println("Full string: " . $String);
