我正在尝试使用 PHP 将数据导出到 cdv/xls 文件。我不断收到以下错误:
*“警告:mysql_query():提供的参数不是有效的 MySQL-Link 资源”*
这是我的代码:
<?php
//Connect the the database
require('../mysql_connect.php') ;
$select = "SELECT * FROM customers WHERE email = 'info@example.com'";
$export = mysql_query ( $select, $dbc ) or die ( "Sql error : " . mysql_error( ) );
$fields = mysql_num_fields ( $export );
for ( $i = 0; $i < $fields; $i++ )
{
$header .= mysql_field_name( $export , $i ) . "\t";
}
while( $row = mysql_fetch_row( $export ) )
{
$line = '';
foreach( $row as $value )
{
if ( ( !isset( $value ) ) || ( $value == "" ) )
{
$value = "\t";
}
else
{
$value = str_replace( '"' , '""' , $value );
$value = '"' . $value . '"' . "\t";
}
$line .= $value;
}
$data .= trim( $line ) . "\n";
}
$data = str_replace( "\r" , "" , $data );
if ( $data == "" )
{
$data = "\n(0) Records Found!\n";
}
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=export.xls");
header("Pragma: no-cache");
header("Expires: 0");
print "$header\n$data";
?>
任何帮助是极大的赞赏!
