How can I extract a link from a PHP string?

Question

Parsing

Hello. How can I find the URL in the text and put it in the "[a]" tag using php?
For example, there is a message "Hi! My page is localhost/mypage123 Go here!"
The final HTML page should look like this: "Hi! My page is [a href="/away/ localhost/mypage123 "] http://localhost/mypage123[/a] Go here everyone!"
This is done in VK and on other services. Thank you!

$text = "Моя страница http://localhost/user/1 Переходите все сюда! http://localhost/user/1";


function replace_href($text)
{
  $words = explode(' ', $text);

  for ($i=0; $i < count($words); $i++) 
  { 
    if(strpos($words[$i], 'http://') !== false || strpos($words[$i], 'https://'))
    {
      $words[$i] = '<a href="'.$words[$i].'">'.$words[$i].'</a>';
    }

    @$new_text = $new_text.' '.$words[$i];
  }


  return @$new_text;
}


echo replace_href($text);

A little shitty code, but working)))
