Replicate PHP pack('H*' ... in autoit

[Kyan]

Hey

I don't know PHP, was trying to get the same output of PHP pack function, already read http://php.net/manual/en/function.pack.php but didn't found a proper translation for "high nible"

I tried with StringFormat('%X',"6D2222E8B845C7B2199357B5FAF9B2C57C8FDAB4") but isn't the same thing

I found this page http://perplexed.co.uk/960_php_pack_function.htm but I don't know how to replicate it in autoit

Can someone lend a hand and point me in the right direction?

@Kyan, try this:

Func _packH($sInput)
    Local $sReply = ""
    For $xx = 1 To StringLen($sInput) Step 2
        $sReply &= Chr(Dec(StringMid($sInput, $xx, 2)))
    Next
    Return $sReply
EndFunc   ;==>_packH

@Luigi, if is a non pair hex string like 7chrs long, how shoud I pad it?

'0'&$7chrStr or $7chrStr&'0'?

[Kyan]

it should be padded from the left. tested the output using this site http://writecodeonline.com/php/ (use bin2hex() on php and Binary() to check if the pack output matches)

pack's php have many options... in the past, I need a pack option too, after many try, I build the function above, I need the option H, becouse packH.

but, have the another pack's options...

BTW, packH looks nothing more than:

Func _packH($sInput)
    Return ((StringLeft($sInput, 2) = "0x") ? _
        BinaryToString($sInput):BinaryToString("0x" & $sInput))
EndFunc

To me... or am I missing something?

Damn, there's such inline operators? wow
