PHP's progress statistics on questionnaire results

PHP statistics on the results of the questionnaire

Background:

As a result of the specific work, I made a paper questionnaire, the main content of the questionnaire is to allow users to 10 requirements (numbered A, b ...). ) to prioritize, so I get a good hundreds of copies similar to A>i>h>g>d .... and other results.

Goal:

Based on the user's sequencing results, these 10 requirements were quantified and the final result would be a:78,b:68,c:70 ... to find out which one is relatively important, while others are relatively unimportant.

Practice:

According to the number of ranked position, to assign a different weight, statistics all the results, the weights are summarized. For example, the result of "Abcdefghij" indicates that A has 10 points, J has 1 points and D has 7 points.

Knowledge Points:

file read; loop; associative array; array sort.

PHP Code:

1 $rs=Array("A" =>0, "B" =>0, "C" =>0, "D" =>0, "E" =>0, "F" =>0, "G" =>0, "H" =>0, "I" =>0, "J" =>0);2 $handle=fopen('./file.txt ', ' R ');3  while(!feof($handle))4 {5     $string=fgets($handle, 1024);6      for($i= 0;$i<strlen($string);$i++)7     {8         $t=Strtoupper($string[$i]);9         if(isset($rs[$t]))Ten             $rs[$t] =$rs[$t]+strlen($string) -$i; One     } A } - fclose($handle); - Arsort($rs); the Var_dump($rs);

Description: File.txt is a text file in which each line represents the result of a questionnaire, similar to something like "Abcdefghij". How did this file get out? Well, I admit that I did not manually input it, I found some people to help (why not do online questionnaires?) Save this trouble)
