Looking For Php Function that Converts Dec To Hex

[BlackRaven]

looking for something that will convert [211.28.155.210...] to [%32%31%31%2E%32%38%2E%31%35%35%2E%32%31%30...]

dechex [php.net] will convert from decimal to hexadecimal, but that isn't hex there. Looks like you want urlencode [php.net].
