使用php [关闭]基于文本中最重复的单词自动生成标题

I would like to generate a title automatically based on the most repeated word in a text using PHP. Example: if the the word "PHP" is repeated the most in a text The title would be : "The text is about PHP".... and so on. I have no clue what to do or from where to start.

Can anyone help me with this?

if i must complete your homework assignment for you, i require full attribution within the paper and the link to this question also in said paper.

i also require that you actually read, understand and attempt to run this code to enable you to understand it.

//get all the test from the file
$text_from_file = file_get_contents("filename.txt");

//get all the words within that text
$words = str_word_count($text_from_file , 1);

//count up all the unique words within the array
$unique = array_count_values($words);

//sort by most to least frequent
arsort($unique); //arsort required to keep keys and values together

//since we dont know the key values here, we need to use foreach
foreach($unique as $key => $val) {
  echo("The most common word is " . $key . " which occurs " . $val . " times");

  break; //always break after the first echo
}

using

print_r( array_count_values(str_word_count($text, 1)) );

will give you a count of all words. You can then choose the top one when sorted ?

rsort

will give you a sorted array from high to low

<?php
function mostRepeated($string = false, $words_num = 5) {
    $string = strtolower($string);
    // extend this array
    $omit_words = array('the', 'a', 'an', 'in', 'at', 'by', 'of', 'was', 'is', 'he', 'she');

    $words = explode(' ', $string);
    foreach($words as $k => $v) {
        if(in_array($word, $omit_words)) unset($words[$k]);
    }

    $count = array_count_values($words);
    arsort($count);
    $result = array();
    foreach($count as $k => $v) {
       $result[] = $k;
    }

    return $result;
}

$text = 'PHP foo Bar php foO pHp';
$most_repeated_words_array = mostRepeated($text, 3);
print_r($most_repeated_words_array);
?>

output:

    Array
(
    [0] => php
    [1] => foo
    [2] => bar
)
