在PHP中基于两列SQL查询创建摘要表

Question

我正在寻找一些帮助来构建将在SQL查询输出中使用的通用PHP函数的帮助

SELECT DISTINCT categoryID, StatusID, COUNT( * ) FROM tableA GROUP BY categoryID

样本结果：

categoryID   StatusID    COUNT( * )  
CategoryB    On Hold      1
CategoryA    On Hold      4
CategoryC    On Hold      3
CategoryB    Draft        1

数据库中可以有任意数量的CategoryID和状态...

并返回TABULAR表格式：

我想要的结果是这样的：

Status Summary Table by Category: 
---------------------------------------------------------
          | CategoryA | CategoryB | CategoryC | ... | TOTAL
Completed |    0      |     1     |    0      | ... |  1
On Hold   |    4      |     0     |    3      | ... |  7
Draft     |    0      |     1     |    1      | ... |  2
---------------------------------------------------------
TOTAL:    |    4      |     2     |    4      | ... |  10

我知道了！ -我希望这会在将来对其他人有所帮助。这不是漂亮的代码，但是它可以工作，并且它很遗传，因此可以根据需要使用。

$sql="SELECT DISTINCT categoryID, statusID, COUNT( * ) as Count1 FROM entries GROUP BY categoryID" ;    
    $results = mysql_query($sql, $con);

    // Now that we have both Status and Category, lets place the counts in the right cells: 

    echo displayTabularSum ($myarray,"status","category",1) ;

现在，我使用的功能是：

function displayTabularSum($myarray, $table1,$table2,$includeTotals)
    {

    // First get all data from $table1 into an array
        $sql = "SELECT * FROM $table1 WHERE 1";
        $results= mysql_query($sql);    
        $statusCodes= getsqlresultintoarray ($results) ;

    // Second: get all  data from $table2 into an array
        $sql = "SELECT * FROM $table2 WHERE 1";
        $results= mysql_query($sql);
        $categoryCodes= getsqlresultintoarray ($results) ;

    // Now create the results table with appropriate values in columns
    $statusTable=array();
    $out = '';
    $first = true;
    $cT=array();
    for ($x=0; $x';
                    for ($y=0; $y'.$categoryCodes[$y][1].'';                
                    }
                    if ($includeTotals) $out.= 'Total';                
                    $out.= '';             
                    $first = false;
                }   
            $out .="";
            $out .="".$statusCodes[$x][1]."";
            $rT=0;
            for ($y=0; $y";          
                $c1=searchForId($categoryCodes[$y][0], $myarray, "categoryID");
                $c2=searchForId($statusCodes[$x][0], $myarray, "statusID");                                 
                $count1=0;      
                $same=($c1==$c2);               
                If ( $same ) {
                    If ($c1==99999  OR $c2==99999) {
                        // do nothing...   These are NULLs
                    } else {

                        $count1=$count1+$myarray[$c1]['Count1'];                    
                    }
                }           
                $out .= $count1;
                $rT=$count1+$rT;
                $cT[$y]=$cT[$y]+$count1; // Collecting column Totals

                $out .="";                 

            }
            if ($includeTotals) $out.= ''.$rT.'';       // display rowTotal
            $out .="";

        }
        if ($includeTotals) {  // Display the column Total before closing table. 
            $cT1=0;
            $out .="";
            $out.= 'Total:';               
            for ($x=0; $x'.$cT[$x].'';      
                $cT1=$cT1+$cT[$x];
            }   
            $out.= ''.$cT1.'';             
            $out .="";
        }
        $out .="";

    return $out;
    } 



    Function getresultsintoarray1 ($results)
    {  // Function to get all results from a SQL QUery into an Array.
        $num_rows = mysql_num_rows($results);
        $myarray=array();
        if ($num_rows>0) {
            while($row = mysql_fetch_assoc($results))
            {
                $myarray[] = $row;
            } 
        }else
        {   
            echo " No data found on database... " ; 

                unset($myarray);
                $myarray=array();
        }

    return $myarray; 
    }
    function getsqlresultintoarray ($get)   // YES
    {
        $num_rows = mysql_num_rows($get);
         $returnArray=array(); 
         $i=0;
        while($row1 = mysql_fetch_array($get)) {
            $returnArray[$i][0]=$row1[0];  // This is the ID
            $returnArray[$i][1]=$row1[1];  // This is the name
            $i++;
        }

    return $returnArray; 
    }


    function searchForId($id, $array, $field) 
    {
    If (count($array)>0) {
       foreach ($array as $key => $val) {
           if ($val[$field]     === $id) {
           return $key;
           }
       }
       }
       return 99999;
    }

如果有人对如何改进有任何想法，我将不胜感激！
