在 php 中导出 frm mysql 表时,我需要在 excel spreedsheet 中使列名加粗。请检查下面给出的代码:
<?php
include '../Scripts/connect.php';
$sql = "Select u.firstname, u.lastname, q.module, q.title, q.description, a.option, a.correctAnswer, a.userAnswer, a.isCorrect FROM table1 a INNER JOIN table2 u on u.userID = a.user INNER JOIN table3 q on q.questionPageID = a.questionPageID";
$result = @mysql_query($sql) or die("Couldn't execute query:
".mysql_error().'
'.mysql_errno());
header('Content-Type: application/vnd.ms-excel'); //define header info for browser
header('Content-Disposition: attachment; filename='.$dbTable.'Answers'.date('Ymd').'.xls');
header('Pragma: no-cache');
header('Expires: 0');
for ($i = 0; $i < mysql_num_fields($result); $i++) // show column names as names of MySQL fields
echo mysql_field_name($result, $i)."\t";
print("\n");
while($row = mysql_fetch_row($result))
{
//set_time_limit(60); // you can enable this if you have lot of data
$output = '';
for($j=0; $j < mysql_num_fields($result); $j++)
{
if(!isset($row[$j]))
$output .= "NULL\t";
else
$output .= "$row[$j]\t";
}
$output = preg_replace("/\r\n|\n\r|\n|\r/", ' ', $output);
print(trim($output))."\t\n";
}
?>
现在它只是以正常格式导出数据。
