Converter

[Anon]

Hi,

I try to convert a string to a hex value:
$string = "wouter";

for ($i = 0; $i < strlen($string); $i++)
{
$HEXConv = DecHex(ord(substr($string, $i, 1)));
$Hexvalue = $Hexvalue . "$HEXConv";
}

Now we got in $Hexvalue a hex value. ;-)

Now I wanna go back (hex --> string), but how?

$string = "wouter";
$Hexvalue = '';

for ($i = 0; $i < strlen($string); $i++)
{
$Hexvalue .= DecHex(ord(substr($string, $i, 1)));
}

echo $Hexvalue."<BR>";

$string='';
for ($i = 0; $i < strlen($Hexvalue); $i+=2)
{
$string .= chr(hexdec(substr($Hexvalue, $i, 2)));
}
echo $string."<BR>";
exit;
