If you have a unknown URL and want to add a query string to it, this package is what you are looking for.
composer require nyholm/append-query-string
$url = 'https://nyholm.tech?example=yes';
$queryString = http_build_query(['foo'=>'bar']);
$result = append_query_string($url, $queryString);
echo $result;
// https://nyholm.tech?example=yes&foo=barYes, this is pretty much as writing:
$result = $url . $queryString;But it will support if URL has query string or not. It will also if a URL hash fragment is used.
There are three different modes you can use with append_query_string.
APPEND_QUERY_STRING_IGNORE_DUPLICATE(default)APPEND_QUERY_STRING_REPLACE_DUPLICATEAPPEND_QUERY_STRING_SKIP_DUPLICATE
They are easiest explained with examples.
$url = 'https://nyholm.tech?foo=x&a=1';
$queryString = http_build_query(['a'=>'2']);
$result = append_query_string($url, $queryString, APPEND_QUERY_STRING_IGNORE_DUPLICATE);
echo $result;
// https://nyholm.tech?foo=x&a=1&a=2$url = 'https://nyholm.tech?foo=x&a=1';
$queryString = http_build_query(['a'=>'2']);
$result = append_query_string($url, $queryString, APPEND_QUERY_STRING_REPLACE_DUPLICATE);
echo $result;
// https://nyholm.tech?foo=x&a=2$url = 'https://nyholm.tech?foo=x&a=1';
$queryString = http_build_query(['a'=>'2']);
$result = append_query_string($url, $queryString, APPEND_QUERY_STRING_SKIP_DUPLICATE);
echo $result;
// https://nyholm.tech?foo=x&a=1
