How to encode only queryparams in a url string?

I want to encode only queryparams in a url string using php, url string given below

https://torrentz-proxy.com/search?q=linux format 2015 added<6m leech>1 seed>1#12345

urlencode() gives https%3A%2F%2Ftorrentz-proxy.com%2Fsearch%3Fq%3Dlinux+format+2015+added%3C6m+leech%3E1+seed%3E1

actually I need https://torrentz-proxy.com/search?q=linux%20format%202015%20added%3C6m%20leech%3E1%20seed%3E1#12345

How to do this ? Is there any native php function to do this ?

EDIT

URL is auto generated (not by me), sample like

http://example.com/abc?a=1 a&b=2 b&c=3+c#123

The simplest way would be to :

  • get the base url with explode
  • encode only the query string (decode first to make sure to not encode twice)
  • make sure to replace # with %23
$myUrl = 'https://torrentz-proxy.com/search?q=linux format 2015 added<6m leech>1 seed>1#12345';
$finalUrl = explode("?", $myUrl)[0] . "?" . urlencode(urldecode(parse_url(str_replace('#', '%23', $myUrl), PHP_URL_QUERY)))

This is giving a full encoded query string "https://torrentz-proxy.com/search?q%3Dlinux+format+2015+added%3C6m+leech%3E1+seed%3E1%2312345"

Then replace %23 with # again if you like (as requested from the your question)

$finalUrl = str_replace('%23', '#', $finalUrl);

This would do

    function encodeURI($url) {
    // http://php.net/manual/en/function.rawurlencode.php
    // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/encodeURI
    $unescaped = array(
        '%2D'=>'-','%5F'=>'_','%2E'=>'.','%21'=>'!', '%7E'=>'~',
        '%2A'=>'*', '%27'=>"'", '%28'=>'(', '%29'=>')'
    );
    $reserved = array(
        '%3B'=>';','%2C'=>',','%2F'=>'/','%3F'=>'?','%3A'=>':',
        '%40'=>'@','%26'=>'&','%3D'=>'=','%2B'=>'+','%24'=>'$'
    );
    $score = array(
        '%23'=>'#'
    );
    return strtr(rawurlencode($url), array_merge($reserved,$unescaped,$score));

   }

I found this here as an alternative to encodeURI() of JS.

You need to parse the URL, extract the query param values, encode them and build the URL back together.

function query_param_encode($url)
{
    $url = parse_url($url);
    $url_str = "";
    if (isset($url['scheme']))
        $url_str .= $url['scheme'].'://';
    if (isset($url['host']))
        $url_str .= $url['host'];
    if (isset($url['path']))
        $url_str .= $url['path'];
    if (isset($url['query']))
    {
        $query = explode('&', $url['query']);
        foreach ($query as $j=>$value)
        {
            $value = explode('=', $value, 2);
            if (count($value) == 2)
                $query[$j] = urlencode($value[0]).'='.urlencode($value[1]);
            else
                $query[$j] = urlencode($value[0]);
        }
        $url_str .= '?'.implode('&', $query);
    }
    if (isset($url['fragment']))
        $url_str .= '#'.$url['fragment'];

    return $url_str;
}

This encodes your URLs as

https://torrentz-proxy.com/search?q=linux+format+2015+added%3C6m+leech%3E1+seed%3E1#12345

http://example.com/abc?a=1+a&b=2+b&c=3%2Bc#123

Use something like this:

<?php

$url = 'https://torrentz-proxy.com/search?q=linux format 2015 added<6m leech>1 seed>1#12345';

$questPos = strpos($url, '?q');
$query = explode('#', substr($url, $questPos+3));
$encodedUrl = substr($url, 0, $questPos+3) . urlencode($query[0]);

foreach (array_slice($query, 1) as $frag) {
    $encodedUrl .= '#' . $frag;
}

var_dump($encodedUrl);

that will output: string(89) "https://torrentz-proxy.com/search?q=linux+format+2015+added%3C6m+leech%3E1+seed%3E1#12345"
