将数据从mysql插入phpexcel的数组答案

【问题描述】：

我正在使用 PHPEXCEL 类将数据和柱形图从 mysql 导出到 excel。

如果我从 phpexcel 中的示例读取使用数组

$sheet = array(

  array(
    '',
    '2010',
    '2011',
    '2012',
  ),
  array(
    'Q1',
    '12',
    '15',
    '21',
  ),
  array(
    'Q2',
    '56',
    '73',
    '86',
  ),
  array(
    'Q3',
    '52',
    '43',
    '66',
  ),
  array(
    'Q4',
    '52',
    '33',
    '46',
  )
);




foreach($sheet as $row => $columns) {
    foreach($columns as $column => $data) {
        $objWorksheet->setCellValueByColumnAndRow($column, $row + 1, $data);
    }
}
?>

我有 mysql 代码：

$gdg = mysql_query("SELECT a.building_id, b.building_name FROM ticket_open a JOIN m_building b ON a.building_id = b.building_id GROUP BY b.building_id ORDER BY b.building_name ASC");
     while($hsldgd = mysql_fetch_array($gdg))                    
     {

        $gdgid = $hsldgd['building_id']; 
        $gdgname = $hsldgd['building_name'];

            $comp = mysql_query("SELECT ifnull(count(ticket_no),0) as jcomp FROM ticket_open WHERE STATUS = 'completed' AND 
                                 building_id = '$gdgid' ");
            $hslcomp = mysql_fetch_array($comp);    

            $ncomp = mysql_query("SELECT ifnull(count(ticket_no),0) as jncomp FROM ticket_open WHERE STATUS != 'completed' AND 
                                 building_id = '$gdgid'");
            $hslncomp = mysql_fetch_array($ncomp);  


        $jmlnot = $hslncomp['jncomp'];
        $jmlcomp = $hslcomp['jcomp'];
        $jmltick = $hslncomp['jncomp'] + $hslcomp['jcomp'] ;


        $sheet = array (
                array (

                $gdgname,
                $jmlnot,
                $jmlcomp,
                $jmltick,
                ),
            );


foreach($sheet as $row => $columns) {
foreach($columns as $column => $data) {
    $objWorksheet->setCellValueByColumnAndRow($column, $row + 1, $data);
}
}

这段代码只读取最后一个数据，而不是所有数据

请帮帮我:)

谢谢，

【问题讨论】：

你试过调试它，看看你是否从mysql部分得到了正确的结果？（获取+构建数组）
您的问题可能在这里 -$sheet = array。 while 循环的每次迭代都会覆盖变量。
另外，你不应该在循环中使用 mysql 查询，它非常低效
谢谢，@Gal，是的，我在 sheet = array 的问题......我不知道为什么它不能循环，但如果不插入到数组中，它仍然在 mysql 中循环......

【解决方案1】：

试试下面的代码：

$sheet = array();
$gdg = mysql_query("SELECT a.building_id, b.building_name FROM ticket_open a JOIN m_building b ON a.building_id = b.building_id GROUP BY b.building_id ORDER BY b.building_name ASC");
     while($hsldgd = mysql_fetch_array($gdg))                    
     {

        $gdgid = $hsldgd['building_id']; 
        $gdgname = $hsldgd['building_name'];

            $comp = mysql_query("SELECT ifnull(count(ticket_no),0) as jcomp FROM ticket_open WHERE STATUS = 'completed' AND 
                                 building_id = '$gdgid' ");
            $hslcomp = mysql_fetch_array($comp);    

            $ncomp = mysql_query("SELECT ifnull(count(ticket_no),0) as jncomp FROM ticket_open WHERE STATUS != 'completed' AND 
                                 building_id = '$gdgid'");
            $hslncomp = mysql_fetch_array($ncomp);  


        $jmlnot = $hslncomp['jncomp'];
        $jmlcomp = $hslcomp['jcomp'];
        $jmltick = $hslncomp['jncomp'] + $hslcomp['jcomp'] ;


        $sheet[] = array (
                $gdgname,
                $jmlnot,
                $jmlcomp,
                $jmltick
                );

foreach($sheet as $row => $columns) {
foreach($columns as $column => $data) {
    $objWorksheet->setCellValueByColumnAndRow($column, $row + 1, $data);
}
}

如果这不起作用，请 var_dump $sheet 变量。

P.S 正如我之前提到的，您可能想要修复您的 mysql 查询。
