JavaScript encodeURIComponent vs PHP ulrencode

The difference between them is that the PHP's urlencode encodes space开发者_StackOverflow中文版s with + instead of %20?

What are the functions that do the same thing for both the languages?

Use rawurlencode instead of urlencode in PHP.

Follow this link at php's own documention rawurlencode

rawurlencode will do the trick, the link is for reference.

Actually even with JavaScript encodeURIComponent and PHP rawurlencode, they are not exactly the same too, for instance the '(' character, JavaScript encodeURIComponent will not convert it however PHP rawurlencode will convert it to %28. After some experiments and tips from others such as this question another Stackoverflow question.

I found the ultimate solution here.

All you need to do is use the add following code

function fixedEncodeURIComponent(str) {
    return encodeURIComponent(str).replace(/[!'()*]/g, function(c) {
        return '%' + c.charCodeAt(0).toString(16);
    });
}

They will be EXACTLY the same now, for example

fixedEncodeURIComponent(yourUrl) (JavaScript) = (PHP) rawurlencode(yourUrl)

no problem with decode, you can use decodeURIComponent() for JavaScript and rawurldecode for PHP

I was having the same problem between rawurlencode() and encodeURIComponent(). The difference for me was that I didn't discover the issue until using encodeURIComponent() in numerous source files, so going back to fix and change them all and then re-test everything was not an option.

Fortunately, JS gives you the ability to "hijack" built-in functions by assigning the same name to a new function. You can thus change the behavior of encodeURIComponent() with a very slight modification to Phantom1412's code, and without having to recode anything.

Just put this script in your page before your code makes any calls to encodeURIComponent():

var encodeURIComponentOld = encodeURIComponent;
encodeURIComponent = function(str) {
    return encodeURIComponentOld(str).replace(/[!'()*]/g, function(c) {
         return '%' + c.charCodeAt(0).toString(16);
    });
};
