Use PHP questionnaire survey results statistics

This article mainly introduces the statistics of questionnaire survey results using PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

Background:

Due to specific work reasons, I made a paper questionnaire. The main content of the questionnaire is to ask users to answer their requirements ( Numbered A, B....) for priority sorting, so the results I got were hundreds of results similar to A>I>H>G>D.... and so on.

Goal:

Conduct a quantitative evaluation of this requirement based on the user's ranking results. The final result is expected to be A:, B:, C:.... ., to find out which elements are relatively important and others are relatively unimportant.

Method:

According to the ranking of the numbers, assign different weights, count all the results, and summarize these weights. For example: The result "ABCDEFGHIJ" means that item A gets points, item J gets points, and item D gets points.

Knowledge points:

File reading; looping; associative array; array sorting.

php code:

 $rs =array("A"=>,"B"=>,"C"=>,"D"=>,"E"=>,"F"=>,"G"=>,"H"=>,"I"=>,"J"=>);
 $handle = fopen('./file.txt', 'r');
 while(!feof($handle))
 {
   $string = fgets($handle, );
   for($i=;$i<strlen($string);$i++)
   {
     $t = strtoupper($string[$i]);
     if(isset($rs[$t]))
       $rs[$t] = $rs[$t]+ strlen($string) - $i;
   }
 }
 fclose($handle);
 arsort($rs);
 var_dump($rs);
