base64编码PHP中的GET变量

Question

I am trying to get php to encode after = but before &.

$actual_link = "$_SERVER[REQUEST_URI]";
$out = substr(strstr($actual_link, '?'), strlen('?'));
$out = urlencode(base64_encode($out));
header('Location: http://'.$_SERVER[HTTP_HOST].'/workenv/img/create.php?'.$out.'');

^ That encodes the whole string not each one. For example:

http://www.example.com/data.php?title=hi&apple=true

Would Be:

http://www.example.com/data.php?title=URLENCODEANDBASE64&apple=URLENCODEANDBASE64`

Try this:

<?php
$actual_link = "http://www.example.com/data.php?title=hi&apple=true";
$out = substr(strstr($actual_link, '?'), strlen('?'));
$arr = explode('&', $out);
for($i=0;$i<count($arr);$i++){
    $arr2 = explode('=', $arr[$i]);
    $arr2[1] = urlencode(base64_encode($arr2[1]));
    $arr[$i] = implode('=', $arr2);
}
$out = implode('&', $arr);
echo $out;
?>
