HTTP_REQUEST Special characters

ahoo75

Hi. I am using PHP ver 5.6 + apache 2 on linux server. having problem matching signature for payment gateway. Found out "+" character is missing in the HTTP_REQUEST. It shows as space, other special characters can be display. Apache config already set default locale to UTF8 but still not working. Please advice. Thank you

Sounds like a job for urlencode(), perhaps? (Tough to say for sure without seeing the relevant code.)

Hi NogDog. Thank you for replying. We provide a postbackurl to the payment gateway once payment info submitted. My system is suppose to retrieve the payment status using the HTTP POST method. My system unable to match their signature due to this "+" character missing. I suppose urlencode() function is not applicable here. Thank you

That's because + is the URL encoding of the space character. To have a literal + in a URL it should be encoded as %2B. Tough to say more without seeing the relevant code, but if you're receiving URLs with unencoded + signs in them then whoever is sending them is making a mistake.

(By the same token, a URL should not have a literal space in it. If there are any, then it's probably due to an unencoded +.)
