What is the equivalent of JavaScript's encodeURIcomponent function in PHP?

Answers:

Answer

Try rawurlencode. Or to be more precise:

function encodeURIComponent($str) {
    $revert = array('%21'=>'!', '%2A'=>'*', '%27'=>"'", '%28'=>'(', '%29'=>')');
    return strtr(rawurlencode($str), $revert);
}

This function works exactly how encodeURIComponent is defined:

encodeURIComponent escapes all characters except the following: alphabetic, decimal digits, - _ . ! ~ * ' ( )

Answer

Did you try urlencode ?

Answer

function encodeURIComponent($string) {
   $result = "";
   for ($i = 0; $i < strlen($string); $i++) {
      $result .= encodeURIComponentbycharacter(urlencode($string[$i]));
   }
   return $result;
}

function encodeURIComponentbycharacter($char) { if ($char == "+") { return "%20"; } if ($char == "%21") { return "!"; } if ($char == "%27") { return '"'; } if ($char == "%28") { return "("; } if ($char == "%29") { return ")";

how is this code?
I encoded each tiers.
actually it's not same as encodeURI, but you can encode but host name and "/"

function encodeURI($url) {
    if(__empty($url))return $url; 

    $res = preg_match('/.*:\/\/(.*?)\//',$url,$matches);
    if($res){

        // except host name
        $url_tmp = str_replace($matches[0],"",$url);

        // except query parameter
        $url_tmp_arr = explode("?",$url_tmp);

        // encode each tier
        $url_tear = explode("/", $url_tmp_arr[0]);
        foreach ($url_tear as $key => $tear){
            $url_tear[$key] = rawurlencode($tear);
        }

        $ret_url = $matches[0].implode('/',$url_tear);

        // encode query parameter
        if(count($url_tmp_arr) >= 2){
            $ret_url .= "?".$this->encodeURISub($url_tmp_arr[1]);
        }
        return $ret_url;
    }else{
        return $this->encodeURISub($url);
    }

}
