Codeigniter 4 Handle Request URI Segment If the URL is empty – PHP

I am using Codeigniter 4 framework and I have a function for getting the URI segment like

    $bahasa = $request->uri->getSegment(1);
    $url = $request->uri->getSegment(2);
    $content = $request->uri->getSegment(3);

the code is working if the URL most like:
http://localhost:8080/segment1/segment2/segment3
but if I put the URL like http://localhost:8080/segment1/ the code is an error, the error is
CodeIgniterHTTPExceptionsHTTPException Request URI segment is out of range: 2

    Just use isset function to check either the segment is exists or not. Like bellow:

    $url = isset( $request->uri->getSegment(2) ) ? $request->uri->getSegment(2) : '';

    That’s it!

    you can use this to check availability of your segement request

    if($request->uri->getSegment(2) || $request->uri->getSegment(3)){
//response if the request is available
}else{
//response if the request is not available
}

    if you still confuse you can read this documentation :

    Solution

    Disable Throwing Exceptions

    By default, some methods of this class may throw an exception. If you
    want to disable it, you can set a special flag that will prevent
    throwing exceptions.

    <?php

// Disable throwing exceptions
$uri->setSilent();

// Enable throwing exceptions (default)
$uri->setSilent(false);

    Hence if your sample URI is http://localhost:8080/segment1/:

    // $bahasa will be set to 'segment1'.
$bahasa = $request->uri->setSilent()->getSegment(1);
// $url will be set to '' (empty string).
$url = $request->setSilent()->uri->getSegment(2);
// $content will be set to '' (empty string).
$content = $request->setSilent()->uri->getSegment(3);

    Extra tip:

    You can also set a different default value for a particular segment by
    using the second parameter of the getSegment() method. The default
    is empty string. – URI Segments

    best way to handle local and server segment issue need to change getSegment function

    getSegment function you can find system/http/URI.php

    getSegment function will look like this by default

    public function getSegment(int $number, string $default = ''): string
    {
        // The segment should treat the array as 1-based for the user
        // but we still have to deal with a zero-based array.
        $number--;

        if ($number > count($this->segments) && ! $this->silent) {
            throw HTTPException::forURISegmentOutOfRange($number);
        }

        return $this->segments[$number] ?? $default;
    }

    need to change segment number like

     public function getSegment(int $number, string $default = ''): string
    {
        // The segment should treat the array as 1-based for the user
        // but we still have to deal with a zero-based array.
         $hostname= getenv('HTTP_HOST'); 
          if($hostname=='localhost'){
            $number--;
          }else{ 
//live server 
            $number=$number-2;
          }
        if ($number > count($this->segments) && ! $this->silent) {
            throw HTTPException::forURISegmentOutOfRange($number);
        }
    
        return $this->segments[$number] ?? $default;
    }
