PHP implementation Dynamic histogram improved version, PHP histogram improved version

In this paper, an improved version of dynamic histogram for PHP is analyzed. Share to everyone for your reference. The specific analysis is as follows:

It has been written that if only the dynamic histogram of the case, the principle is still very simple. Because there was a new demand yesterday afternoon, this morning modified again, and the data according to the number of different segmentation display in the table.

The following code to stick out, convenient to see themselves later, the idea is just a spark, today I want to come out to do so, not necessarily next time can also want to think, and do not have to worry about, so write notes is a better form.

 <?php//Calculates the Today's function Last_month_today ($time) {$last _month_time = mktime (Date ("G", $time), date ("I", $time) for the last one months,   Date ("S", $time), date ("n", $time), 0, date ("Y", $time));   $last _month_t = Date ("T", $last _month_time);   if ($last _month_t < date ("J", $time)) {return date ("Y-m-t h:i:s", $last _month_time); Return Date (date ("Y-m", $last _month_time). "-D", $time); }?> <?php include DirName (DirName (dirname (__file__))). '/config.php '; $endDate = Date (' y-m-d '); $date = Strtotime ($endDate); $beginDate = Last_month_today ($date); $sql = ' SELECT count (*) from Newpro where p_date>\ '. $beginDate. ' \ ' and p_date<\ '. $endDate. '\''; $d = db ()->query ($sql)->fetch (pdo::fetch_num); $sql 2 = $sql. ' and Is_pa_check_first=1 and is_pa_check_second=1 and Is_pa_check_third=1 '; $d 2 = db ()->query ($sql 2)->fetch (pdo::fetch_num); $sql 3 = $sql. ' and Is_pa_check_first=1 '; $d 3 = db ()->query ($sql 3)->fetch (pdo::fetch_num); $sql 4 = $sql. ' And Is_pa_check_fiRst=1 and Is_pa_check_second=1 '; $d 4 = db ()->query ($sql 4)->fetch (pdo::fetch_num); Query everyone through auditing: $sqlab = ' Select D_m,sum (SROCE) as Total_score,count (D_m) as Total_number from Newpro where Is_pa_check _first=1 and Is_pa_check_second=1 and Is_pa_check_third =1 Group by D_m ';  $row = db ()->query ($sqlab)->fetchall (PDO::FETCH_ASSOC);?>

  <?php $arr = Array_chunk ($row, 2,false),//2 represents the unit length of the split, false indicates that the index starts with 0 foreach ($arr as $newRow) {$thStr = "
  
   "; $trStr _total_score = " 
   "; $trStr _total_number = " 
   "; $trStr _average_score = " 
    "; $RESULTSTR = ""; foreach ($newRow as $key = + $value) {//echo $key. " = ". $value."; $x = 0; foreach ($value as $key 2 = $value 2) {//Echo $key 2. "=". $value 2. ""; if ($key 2 = = ' D_m ') {$thStr. = " 
    "; Table Header} elseif ($key 2 = = ' Total_score ') {$value 2 = sprintf ("%.2f", $value 2);//2 decimal places reserved $trStr _tota L_score. = " 
    "; $x + = $value 2; } elseif ($key 2 = = ' Total_number ') {$trStr _total_number. = " 
    "; $x/= $value 2; }} $x = sprintf ("%.2f", $x); $trStr _average_score. = " 
    "; } echo " 
   
   
  
  

    the completion of each person is shown in the following table: 
  
 
   
 
    
Product development number
 
   
 
    
Score
 
   
 
    
Total quantity
 
   
 
    
 average score 
". $value 2. "
". $value 2. "
". $value 2. "
". $x. "
 
  
 
 
 
 
  
  ";       Echo $thStr; Echo $trStr _total_number.       ""; Echo $trStr _total_score.       ""; Echo $trStr _average_score.       ""; echo "
 
 "; echo "
"; }?>  

The database is not easy to get, in fact, according to the query table name and field name, it is easy to build a test data table. The key is the idea, no matter how change, the idea is the key.

I hope this article is helpful to everyone's PHP programming.
