Comparing similarity in two arrays!

Good evening guys, I'm having a problem, come on, maybe someone can help me.

$array1 = array();
$array2 = array();
foreach ($paper as $p)
{
    $array1[] = $p->title;
    $array2[] = $p->title;
}

$nbarray1 = count($array1);
$stringSimilarity = 0;

foreach ($array1 as $word1)
{
    $max = null;
    $similarity = null;
    foreach ($array2 as $word2)
    {
        similar_text($word1, $word2, $similarity);
        if ($similarity > $max)
        {
            $max = $similarity;
        }
    }
    $stringSimilarity += $max;
    $resultado = $stringSimilarity / $nbarray1;

    if ($resultado > 90)
    {
        echo '<b>Título 1:</b> ' . $word1 . ' <br><b>Título 2:</b> ' . $word2 . ' <b><br>Resultado: POSSIVELMENTE DUPLICADO - Porcentagem = ' . number_format((float)$resultado, 0, '.', '') . '%<br></b>';
    }
    else
    {
        echo '<b>Título 1:</b> ' . $word1 . ' <br><b>Título 2:</b> ' . $word2 . ' <b><br>Resultado: NÃO DUPLICADO - Porcentagem = ' . number_format((float)$resultado, 0, '.', '') . '%<br></b>';
    }

}

This code has the following OUTPUT

Título 1: A new method for SSD black-box performance test 
Título 2: Novel Solution for the Built-in Gate Oxide Stress Test of LDMOS in Integrated Circuits for Automotive Applications 
Resultado: NÃO DUPLICADO - Porcentagem = 25%
Título 1: Structural Health Monitoring of a rotor blade during statical load test 
Título 2: Novel Solution for the Built-in Gate Oxide Stress Test of LDMOS in Integrated Circuits for Automotive Applications 
Resultado: NÃO DUPLICADO - Porcentagem = 50%
Título 1: Using TTCN-3 in Performance Test for Service Application 
Título 2: Novel Solution for the Built-in Gate Oxide Stress Test of LDMOS in Integrated Circuits for Automotive Applications 
Resultado: NÃO DUPLICADO - Porcentagem = 75%
Título 1: Novel Solution for the Built-in Gate Oxide Stress Test of LDMOS in Integrated Circuits for Automotive Applications 
Título 2: Novel Solution for the Built-in Gate Oxide Stress Test of LDMOS in Integrated Circuits for Automotive Applications 
Resultado: POSSIVELMENTE DUPLICADO - Porcentagem = 100%

Note that I have only 4 titles registered. How would I make the title not try to test its similarity to itself ???

Note that only one title tested with all others, the right should restart the loop with another test title again, and so on until all are tested with all

$ paper is an array of this type

[0] = > object (stdClass) # 97 (26) { ["paper_id"] = > string (1) "1" ["title"] = > string (47) "A new method for SSD black-box performance test" ["author"] = > string (6) "Q. Xie"

Would it be possible after I check the duplicates, update the array of paper objects? In case it has ["status"] = > and I wanted to update this to duplicate if it was found in the previous validations.

If someone with a lot of patience helps to think logic is already happy, I'm catching up but I'm trying to develop: D

This would prevent it from checking the duplicate by putting a if() within the second foreach() :

foreach($array2 as $word2){
//verifica se word1 é diferente de word2, se for igual ele não compara
    if($word1 != $word2){ 
        similar_text($word1, $word2, $similarity);
        if($similarity > $max){ //1)
            $max = $similarity;
        }
    }
}

You can set this start in ways that are less repetitive, for example:

$array1 = array();
$array2 = array();
foreach ($paper as $p) {
   $array1[] = $p->title;
   $array2[] = $p->title;
}

Or just like this:

foreach ($paper as $p) {
   $array1[] = $p->title;
   $array2[] = $p->title;
}
