arrays - how to measure apperance frequency of words in a text with PHP -

-

this question has answer here:

given text (here, convenience, i've put text (text)file), want know how many time(s) each word appear in text.

php provides useful function : str_word_count, which, $format argument set 1, returns simple array of words contained in $string.

this code :

<?php $lines=array_map("findwords",file("words.txt"));  $text=[]; foreach($lines $line) {     $text=array_merge($text,$line); } $words=array_count_values($text);  //order array values desc, preserving keys $words2=[]; ($i=0;$i<=count($words)-1;$i++) {     $numof=max($words);     $key=array_keys($words,$numof)[0];     $words2[$key]=$numof;     unset($words[$key]); }  echo '<pre>'; print_r($words2); echo '</pre>';  function findwords($str) {     return str_word_count($str,1); }
