I have the following strings:

www.adorocinema.com/filmes/filme-226616/fotos
www.adorocinema.com/slideshows/filmes/slideshow-124792
www.adorocinema.com/noticias/filmes/noticia-125494
www.adorocinema.com/filmes/filme-227703
www.adorocinema.com/noticias/filmes/noticia-113312
www.adorocinema.com/filmes/filme-202686
www.adorocinema.com/filmes/filme-144694

How do I make a check that the result is true for:

www.adorocinema.com/filmes/filme-144694
www.adorocinema.com/filmes/filme-202686
www.adorocinema.com/filmes/filme-227703

and false for:

www.adorocinema.com/filmes/filme-226616/fotos
www.adorocinema.com/slideshows/filmes/slideshow-124792
www.adorocinema.com/noticias/filmes/noticia-125494
www.adorocinema.com/noticias/filmes/noticia-113312

You can use a fixed part of the string (site address) and dynamic the part of the movie id:

^www\.adorocinema\.com/filmes/filme-\d+$

Says search at the beginning of the line (^) for www followed by a point (\.) note that it must be escaped with bar plus the fixed string and finally one or more digits at the end of the line ($)

$arr = array(
'www.adorocinema.com/filmes/filme-226616/fotos',
'www.adorocinema.com/slideshows/filmes/slideshow-124792',
'www.adorocinema.com/noticias/filmes/noticia-125494',
'www.adorocinema.com/filmes/filme-227703',
'www.adorocinema.com/noticias/filmes/noticia-113312',
'www.adorocinema.com/filmes/filme-202686',
'www.adorocinema.com/filmes/filme-144694');


foreach($arr as $item){
    if(preg_match('#^www\.adorocinema\.com/filmes/filme-\d+$#', $item, $m)){
        echo 'valido: '. $m[0] .'<br>';
    }
}

Exit:

valido: www.adorocinema.com/filmes/filme-227703
valido: www.adorocinema.com/filmes/filme-202686
valido: www.adorocinema.com/filmes/filme-144694

You can use the function array_filter to take all values that are compatible with regex.

$arr = array(
    'www.adorocinema.com/filmes/filme-226616/fotos',
    'www.adorocinema.com/slideshows/filmes/slideshow-124792',
    'www.adorocinema.com/noticias/filmes/noticia-125494',
    'www.adorocinema.com/filmes/filme-227703',
    'www.adorocinema.com/noticias/filmes/noticia-113312',
    'www.adorocinema.com/filmes/filme-202686',
    'www.adorocinema.com/filmes/filme-144694'
);

$valids = array_filter($arr, function($item) {
    return preg_match('/filmes\/filme-\d+$/', $item);
});

var_dump($valids);

Exit:

array(3) {
    [3]=> string(39) "www.adorocinema.com/filmes/filme-227703"
    [5]=> string(39) "www.adorocinema.com/filmes/filme-202686"
    [6]=> string(39) "www.adorocinema.com/filmes/filme-144694"
}

Note that I only saw the end of the string, so any link that is not "www.adorocinema.." will also be valid.

One more way:

<?php
preg_match('/^(?:http(?:s)?[\:][\/][\/](?:www[\.])?adorocinema[\.]com[\/]filmes[\/])(?:filme[\-]([0-9]{6}))$/i', preg_replace('/([\s]+)/i', '', $odominioface), $resultadodominioface);
if((isset($resultadodominioface[1]) == true) and ($resultadodominioface[1] != null)){
echo "Link ok<br />";
echo "O link do filme é: filme-".$resultadodominioface[1]."<br />";
} else{
echo "O link não é válido!<br />";
echo "Nada como retorno!"
}

?>

Now just put an 'array_filter' or a 'foreach' if you are going to parse many links in array form. regex parses the whole url. Accepts the following urls and as many spaces as you want in urls:

http://adorocinema.com/filmes/filme-226616

https://adorocinema.com/filmes/filme-226616

http://www.adorocinema.com/filmes/filme-226616

https://www.adorocinema.com/filmes/filme-226616

Includes a nested 'preg_replace' within the 'preg_match' in order to clear possible spaces in the 'url'. It’s fully functional. I’ve tested it now.
