Using PHP to export MySQL database for Excel table Many ways, the simplest directly using the PHP fputcsv function, there is a direct input CSV format is also possible, to generate Excel standard format we need to use a third-party plug-in
Method one, using Fputcsv
| The code is as follows |
Copy Code |
Output Excel file header, you can replace user.csv with the file name you want
Header (' Content-type:application/vnd.ms-excel ');
Header (' content-disposition:attachment;filename= ' user.csv "');
Header (' cache-control:max-age=0 ');
Get the data from the database, in order to save memory, do not read the data once to the memory, the subordinate handle in a row to read
$sql = ' SELECT * from tbl where ... ';
$stmt = $db->query ($sql); Open PHP file handle, php://output direct output to browser
$fp = fopen (' php://output ', ' a '); Output Excel Column name information
$head = Array (' name ', ' gender ', ' age ', ' Email ', ' phone ', ' ... ');
foreach ($head as $i = = $v) {
CSV Excel support GBK encoding, be sure to convert otherwise garbled
$head [$i] = iconv (' utf-8 ', ' GBK ', $v);
} Writes data to a file handle via Fputcsv
Fputcsv ($fp, $head); Counter
$cnt = 0;
Every $limit line, refresh the output buffer, not too big, not too small
$limit = 100000; Row-by-line data extraction without wasting memory
while ($row = $stmt->fetch (zend_db::fetch_num)) { $cnt + +;
if ($limit = = $cnt) {//Refresh output buffer to prevent problems caused by excessive data
Ob_flush ();
Flush ();
$cnt = 0;
} foreach ($row as $i = = $v) {
$row [$i] = iconv (' utf-8 ', ' GBK ', $v);
}
Fputcsv ($fp, $row);
} |
Method two, output CSV format data directly in the browser with header
| The code is as follows |
Copy Code |
/* Connect to Database */
$DB _server = "localhost";
$DB _username = "root";
$DB _password = "123456";
$DB _dbname = "MyDB"; Target database name
$DB _tblname = "MyTable"; Target table name
$Connect = @mysql_connect ($DB _server, $DB _username, $DB _password) or Die ("couldn ' t Connect.");
mysql_query ("Set Names ' UTF8 '"); $savename = Date ("Ymjhis"); Export Excel file name
$file _type = "Vnd.ms-excel";
$file _ending = "xls";
Header ("content-type:application/$file _type;charset=utf8");
Header ("content-disposition:attachment; Filename= ". $savename.". $file _ending ");
Header ("Pragma:no-cache"); /* Write Note information */
$now _date = Date ("Y-m-j h:i:s");
$title = "Database name: $DB _dbname, Data sheet: $DB _tblname, Backup date: $now _date";
Echo ("$titlen"); /* Query Database */
$sql = "SELECT * from $DB _tblname";
$ALT _db = @mysql_select_db ($DB _dbname, $Connect) or Die ("couldn ' t Select Database");
$result = @mysql_query ($sql, $Connect) or Die (Mysql_error ()); /* Write table field name */
for ($i = 0; $i < Mysql_num_fields ($result); $i + +) {
Echo Mysql_field_name ($result, $i). ",";
}
echo "n"; /* Write table Data */
$sep = ", T";
while ($row = Mysql_fetch_row ($result)) {
$data = "";
for ($i =0; $i
if (!isset ($row [$i]))
$data. = "NULL". $sep; Working with NULL fields
ElseIf ($row [$i]! = "")
$data. = "$row [$i]". $sep;
Else
$data. = "". $sep; Working with empty fields
}
echo $data. " n ";
}

Example 3, the second one's almost there.
| The code is as follows |
Copy Code |

$start _time = strtotime ($start _date);
$end _time = strtotime ($end _date);
$sql = "Select A.*,b.order_amount,b.money_paid from". $ecs->table (' Invoice '). "As a".
"LEFT join". $ecs->table (' Order_info '). "As B on A.order_id=b.order_sn".
"Where A.add_time >=". $start _time. "and A.add_time <=". $end _time. " ";
$temp _list = $db->getall ($sql);
if ($temp _list) {//have data
$Html = ". Chr (10);
$Html. = '

$temp _time = Date (' y-m-d ', $temp _list[$i [' add_time ']);
$Html. = '

Sometimes Excel will automatically convert the number format, so some mobile phone numbers, identity cards and so on is messy, so you can export, the first defined
| The code is as follows |
