I'm trying to use the unpack function in PHP to convert a text or binary string to its hexadecimal representation (e.g. 'hello' -> '68656c6c6f')


function _hexstring($bin)
{
	list(,$ret) = unpack('h1', $bin);
	return($ret);
}

I'm missing something fundamental here. It returns a blank string. Anybody have an idea? ~BenDilts( void );

Try:

function _hexstring($bin){        list(,$ret) = unpack('H'.strlen($bin)*2, $bin);        return($ret);}

function _hexstring($bin){	list(,$ret) = unpack('h*1', $bin);	return($ret);}

Solved.

Thanks, you pointed me in the right direction!
