How to properly url encode a string

Question

I'm trying to parse a file name to a url string.

the file name is:

201-SALÃO DE JOGOS.jpg

I need the output be exactly this:

201-SAL%c3O%20DE%20JOGOS.jpg

I'm trying like this:

$var = 201-SALÃO DE JOGOS.jpg; echo urlencode($var);

But instead it returns:

201-SAL%C3%83O+DE+JOGOS.jpg

This is not a valid url. I've already tried with htmlspecialchars() and htmlentities() but these do not work.

I need the empty spaces be like %20 not +. That's the only problem — Ivan Moreira

Could I understand why do you want %20 not +? @IvanMoreira — SaidbakR

You need rawurlencode

$filename = "201-SALÃO DE JOGOS.jpg"; print rawurlencode($filename);

mb_rawurlencode is nonsense; rawurlencode works on a byte level and doesn't care about the encoding at all. In fact, the results of both functions are identical. I have no idea why that commenter thought an mb variant would be useful in any way.

Thanks a lot! my code now is $var = '201-SALÃO DE JOGOS.jpg'; echo rawurlencode(utf8_decode($var));

@IvanMoreira: Why you have used utf8_decode when rawurlencode is already giving you exactly want you want?

rawurlencode is not giving me exactly what i want( i don't know why). To make the string be exactly the way i want, i had to use utf8_decode

You could able to use str_replace to replace + with %20:

<?php $var = "201-SALÃO DE JOGOS.jpg"; $output = str_replace('+','%20',urlencode($var)); echo $output; echo "*****"; echo urldecode($output); ?>
