PHP code and $_GET $_POST
Posted on 2012-03-16
I've posted here before about someone elses (non-working) PHP code I am making my way through. The code was written about 2005, if that tells you anything about the version of PHP they were using.
After posting the code, one of your Experts noticed that this was defined in many places:
I have since changed every occurance of $HTTP_GET_VARS to $_GET and $HTTP_POST_VARS to $_POST. My code is still not working but I have made some progress and now it's 'kinda' working.
I have a few questions
1. Does $_POST return the same data in the same way that $HTTP_POST_VARS would have returned? The same question applies to $_GET and $HTTP_GET_VARS.
2. I'm noticing the split function in used throughout the code. I've read that it's deprecated and not advisable to use. below is one example of the split.
My questions regarding this are
- online docs say I should use preg_split(). How would I rewrite this using preg_split
- It looks from the code that's it's splitting on a colon, thing is that I don't see any way a colon could have gotten into the string that CCGetFromGet is returning. Does the colon exist in the array that $_GET returns? If so, I'm not seeing when I do a var_dump($_GET).
$CCSForm = split(":", CCGetFromGet("ccsForm", ""), 2);
//Here is the function it's calling
function CCGetFromGet($parameter_name, $default_value = "")
return isset($_GET[$parameter_name]) ? CCStrip($_GET[$parameter_name]) :$default_value;
