Personal opa,

I have a function that must identify a particular url. If the url is identified, it must be wrapped with the tag <a> and its href property must have the same value as the last url. In case I want only one url and its directories to be converted into links , while other urls remain the same as they are.

Example: The url that I want to link whenever it appears in the text is: www.mysite.com

The problem I'm having is the following: In my role, I'm not able to identify the url without the http. What I need is to identify the url with or without the http protocoloco and make the link have your href filled out correctly.

I need to identify the 3 cases below, but I can only identify the first.

http://www.meusite.com.br
www.meusite.com.br
meusite.com.br

Remembering that urls other than this should not be identified in the function filter. Ex: miite2.com no should be filtered

Here's my function I've tried:

    function checkUrl($text){
        $pattern = "(https?)?://[a-z0-9./&?:=%-_]*";

        preg_match_all($pattern, $text, $matches);
        if( count($matches[0]) > 0 ){
            foreach($matches[0] as $match){
                $text = str_replace($match, "<a href='" . $match . "' target='_blank'>" . $match . "</a>", $text);
            }
        }
        return $text;
    }

$text = "Em http://www.meusite.com.br você encontra muitas dicas sobre o assunto. Na url www.meusite.com.br você encontra especialistas com seus artigos esclarecdores. E claro, meusite.com.br é o melhor site no assunto";

I think my problem is only in the $ pattern variable, where I pass the pattern to be found.

I searched here in the forum but did not find exactly what I needed

Identify URLs and create links

The above link did not help, and I should do this in php.

You can always treat http in the url as follows:

function checkUrl($text){

    //primeiro garantindo que todos vão estar iguais
    $find = ['http://www.meusite.com.br', 'https://www.meusite.com.br', 'www.meusite.com.br'];
    $replace = "meusite.com.br";
    $text = string_replace($find, $replace, $text);

    //depois será possível colocar o http sem duplicar, caso já tivesse antes
    $find = ['meusite.com.br'];
    $replace = "http://www.meusite.com.br";
    $text = string_replace($find, $replace, $text);

    //e o que já estiver funcionando vai tratar tudo agora...
    $pattern = "(https?)?://[a-z0-9./&?:=%-_]*";

    preg_match_all($pattern, $text, $matches);
    if( count($matches[0]) > 0 ){
        foreach($matches[0] as $match){
            $text = str_replace($match, "<a href='" . $match . "' target='_blank'>" . $match . "</a>", $text);
        }
    }
    return $text;
}
