我在一个基于 php 的系统上工作。它的功能之一是允许用户下载一个包含我数据库中一个表中所有信息的 excel 文件。我的问题是,该信息的一个数据被分类给其他用户。因此,我想将该数据的输出转换为星号字符串。
<?PHP
//MySQL Database Connect
include 'datalogin.php';
function cleanData(&$str)
{
$str = preg_replace("/\t/", "\\t", $str);
$str = preg_replace("/\r?\n/", "\\n", $str);
if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"';
}
# filename for download
$filename = "website_data_" . date('Ymd') . ".xls";
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");
$flag = false;
//$result = pg_query("SELECT * FROM data_mapping ORDER BY CE_Hostname") or die('Query failed!');
/*$query = "SELECT * FROM data_mapping";
while(false !== ($row = pg_fetch_assoc($result))) {
//while(false !== ($row = pg_fetch_assoc($result))) {
//$result=mysql_query($query);
$row=mysql_fetch_array($result);
$row=mysql_fetch_assoc ($result);
//$row=$row['Cust_Segment'];
// foreach($data as $row)
# display field/column names as first row
if(!$flag) {
echo implode("\t", array_keys($row)) . "\r\n";
$flag = true;
}
array_walk($row, 'cleanData');
echo implode("\t",($row)) . "\r\n";
}
*/
$sql = 'SELECT CE_Hostname, Cust_Segment, Cust_Site_Name, CE_WAN_IP_Addr, CE_Bkp_IP_Addr, Cust_Name, Svc_Type, com_string FROM data_mapping';
$result = mysql_query($sql);
if (!$result) {
echo "DB Error, could not query the database<br>";
echo 'MySQL Error: ' . mysql_error();
exit;
}
echo "Hostname\t Group/System\t Site Name\t IP ADDR\t BKP IP ADDR\t System Name\t Device Type\t Comm_String\r\n";
while ($row = mysql_fetch_assoc($result)) {
echo implode("\t",($row)) . "\r\n";
}
mysql_free_result($result);
//exit;
?>
我只想转换 comm_string 结果。谢谢。
