URL encoding processing in php

//Visit ftp://bbs.it-home.org/my documents/php tutorial.doc
echo 'jbxue's directory"';
?>

Due to historical reasons, in the early URL encoding regulations, spaces were converted to "+". If you want to be compatible with this encoding rule, you can use the urlencode() function. For example, the following example:

//urlencode() encoding
echo 'test';
 ?>

Next we will talk about, since it can be encoded, of course it can also be decoded. The decoding functions corresponding to the two url encoding functions above are: rawurldecode() and urldecode(), such as those used in the following example:

$a = explode('&', $QUERY_STRING);
$i = 0;
while ($i < count($a))
{
 $b = split('=', $a[$i]);
 echo "Value for Parameter ", htmlspecialchars(urldecode($b[0])),' is ', htmlspecialchars(urldecode($b[1])) , "n";
 $i++;
}
?>
