如何从PHP中的文本中提取名称

I want to extract the name from a paragraph or text content. I am using PHP. I tried to extract the name from below library.

https://packagist.org/packages/php-text-analysis/php-text-analysis

    $text = "my name is maneesh, and my friend name is Paritosh";
    $freqDist = freq_dist(tokenize($text));
    print_r($freqDist); die;

My expected output is : maneesh, Paritosh

Actual result is getting only frequency of word:

   (
        [my] => 2
        [name] => 2
        [is] => 2
        [maneesh] => 1
        [and] => 1
        [friend] => 1
        [Paritosh] => 1
    )

If you are going to use the library you mentioned, you have to train your model. That means, fill them with many possible ways in which people can say their name. But even so, I wouldn't be perfect (depends on how well you trained your model).

Moreover, you are getting only frequency of words because that's the analysis you requested with the method freq_dist. I think you have to use corpus analysis for what you want.
