I have to remove the last element in a string. I used rtrim in php but it is not working.
This is the string:
/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100&make_order=ASC
I need to remove "&make_order=ASC"
Can anyone help me?

Answer 1

$s = '/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100&make_order=ASC';
echo substr($s, 0, strrpos($s, '&'));
Edit:
$url = $base_url.trim( $_SERVER['REQUEST_URI'], "&year_order=".$arr['year_order']."" );
// ^
// |_ replace , with .

Answer 2

trim should work:
$string = "/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100&make_order=ASC";
$string = trim($string, "&make_order=ASC");

Answer 3

There's no guarantee that make_order will be at the end of the query string - or exist at all. To remove the field properly, you'd have to use something like this:
$url = '/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100&make_order=ASC';
// break down the URL into a path and query string
$parsed = parse_url($url);
// turn the query string into an array that we can manipulate
$qs = array();
parse_str($parsed['query'], $qs);
// remove the unwanted field
unset($qs['make_order']);
// rebuild the URL
$rebuilt = $parsed['path'];
if(!empty($qs)) {
$rebuilt .= '?' . http_build_query($qs);
}
echo $rebuilt;

$actual_link = "/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100&make_order=ASC";
echo str_replace("&make_order=ASC","",$actual_link);

Answer 5

$string = "/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100&make_order=ASC";
$args = array_pop(explode($string, "&"));
$string = implode("&", $args);

Answer 6

There are a bunch of ways. The easiest might be:
$i=strrpos($text,'&');
$newstring=substr($text,0,$i);

Answer 7

$str = "/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100&make_order=ASC";
echo $str . "<br>";
echo trim($str,"&make_order=ASC");

Answer 8

if &make_order=ASC is always going to be at the end, you can use strstr() to do this
$str = '/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100&make_order=ASC';
echo strstr($str,'&make_order=ASC',true);

Answer 9

Remove desired key from url.
Use:
$s = '/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100&make_order=ASC';
echo remove_key_from_url($url, 'make_order');
Output :
/search/listing.html?vehicle_type=&year=&make_name=&model_name=&loc_type=3&zipcode=641004&distance=100
Code:
function remove_key_from_url($url, $key) {
if (strpos($url, '?') === false) return $url;
list($left, $right) = explode('?', $url, 2);
parse_str($right, $get);
if (isset($get[$key])) unset($get[$key]);
return $left . '?' . http_build_query($get);
}
