Recently i was working on a chrome extension and came across with an issue where some special characters were escaping and blank space were replacing with ascii code.
There are two method passing query parameter to google search
- passing query parameter in Javascript
- Passing query parameter in PHP
Javascript
// encodes characters such as ?,=,/,&,:
console.log(`?x=${encodeURIComponent('test?')}`);
// expected output: "?x=test%3F"
console.log(`?x=${encodeURIComponent('шеллы')}`);
// expected output: "?x=%D1%88%D0%B5%D0%BB%D0%BB%D1%8B"
PHP
Try rawurlencode. Or to be more precise:
Or
function encodeURIComponent($str) {
$revert = array('%21'=>'!', '%2A'=>'*', '%27'=>"'", '%28'=>'(', '%29'=>')');
return strtr(rawurlencode($str), $revert);
}This function works exactly how encodeURIComponent is defined:
Another customized solution in PHP
function encodeURIComponent($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 '"'; }
