replace urls variable value

Question

I have the following url

/index.php?option=com_zoo&task=item&item_id=292&Itemid=283

What I want to do to replace item_id's value with a variable. I have been checking a couple of php functions like split and parse_str, but I do not know how I to get it to work.

is this a url you are creating for a link? or are you inside index.php and trying to work with the passed value in item_id? — Matt

Is this URL in a string, or the current URL (in the address bar)? — gen_Eric

$url = '/index.php?option=com_zoo&task=item&item_id=292&Itemid=283';

$query = explode('?', $url); // Split the URL on `?` to get the query string
parse_str($query[1], $data); // Parse the query string into an array

echo $data['item_id']; // 292

$newValue = 300;
$data['item_id'] = $newValue; // Replace item_id's value

$url = $query[0].'?'.http_build_query($data); // rebuild URL

echo $url; // '/index.php?option=com_zoo&task=item&item_id=300&Itemid=283";

Try the str_replace function. If you have your URL stored in the variable $url and the variable you want to replace Itemid stored in $ItemID:

$url = str_replace("Itemid", $ItemID, $url);

I think he wants to replace the 292 (item_id's value).

This doesn't replace the value, but the item itself.

yeah actually I wanted to replace the value, Rockets workaround seems to be perfect.

ah ok, I should have looked past the blue "Itemid" and realized it was actually the value you wanted to replace. :)

*this is the exact way of doing it *

 <?php
    $url = '/index.php?option=com_zoo&task=item&item_id=292&Itemid=283';
    $explodeData =parse_url($url);
    $dataReplace = str_replace('item_id','replacedvariable',$explodeData['query'],$count);
    $changedUrl = $explodeData['path']."?".$dataReplace;
    echo $changedUrl;
    ?>
