I want to return the first URL of google search result like: First Url Result

.php code:

<?php
        //Check if submit button is clicked or not
        if (isset($_POST['submit'])) {
            $text = $_POST['text'];
            // echo $text;

            function file_get_contents_curl($url) {
                $ch = curl_init();
            
                curl_setopt($ch, CURLOPT_HEADER, 0);
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //Set curl to return the data instead of printing it to the browser.
                curl_setopt($ch, CURLOPT_URL, $url);
            
                $data = curl_exec($ch);
                curl_close($ch);
            
                return $data;
            }
            
            $query =  $text;
            $url = 'http://www.google.co.in/search?q='.urlencode($query).'';
            echo $url;
            $scrape = file_get_contents_curl($url);
            echo $scrape;
?>

How can i achieve that?
