使用不同的preg_match_all将唯一数组应用于字符串数组

Question

i've a logical problem that i don't know how to solve, i'm a lot confused about it.

I've an array composed in this way:

titoli[
    1 => 'NFL'
    2 => 'Johnny Depp'
    3 => 'Institute of Technology'
    4 => 'Another text'
]

Now, I need to apply different regex to that array, how can i do that and have a single final array?

For now i've written this:

for($i=0;$i<sizeof($titoli);$i++)
{
    if(str_word_count($titoli[$i]) > preg_match_all('/([A-Z][a-zA-Z0-9-]*)([\s][A-Z][a-zA-Z0-9-]*)+/', $titoli[$i]))
{
    preg_match('/([A-Z][a-zA-Z0-9-]*)([\s][A-Z][a-zA-Z0-9-]*)+/', $titoli[$i], $result[$i]);
    $i++;
}
if(str_word_count($my_array[$i]) > preg_match_all('/^[A-Z][a-z]* [a-z]+ [A-Z][a-z]*$/', $titoli[$x]) && preg_match_all('/^[A-Z][a-z]* [a-z]+ [A-Z][a-z]*$/', $titoli[$i]) > 0) //controlla che nel titolo non siano state messe tutte le parole con l'iniziale maiuscola
{
    preg_match('/^[A-Z][a-z]* [a-z]+ [A-Z][a-z]*$/', $titoli[$x], $result_b[$y], PREG_PATTERN_ORDER);
    $y++;
}
}

Well, you could merge the arrays then extract the unique values:

$merged = array_merge($array1, $array2, $array3);

$unique = array_unique($merged);

Where $array1, $array2 and $array3 are the results of the preg_match_all functions.
