本文實(shí)例講述了php使用指定編碼導(dǎo)出mysql數(shù)據(jù)到csv文件的方法。分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：

<?php

/*

* PHP code to export MySQL data to CSV

*

* Sends the result of a MySQL query as a CSV file for download

* Easy to convert to UTF-8.

*/

/*

* establish database connection

*/

$conn = mysql_connect('localhost', 'login', 'pass') or die(mysql_error());

mysql_select_db('database_name', $conn) or die(mysql_error($conn));

mysql_query("SET NAMES CP1252");

/*

* execute sql query

*/

$query = sprintf('SELECT field1,field2 FROM table_name');

$result = mysql_query($query, $conn) or die(mysql_error($conn));

/*

* send response headers to the browser

* following headers instruct the browser to treat the data as a csv file called export.csv

*/

header('Content-Type: text/csv; charset=cp1252');

header('Content-Disposition: attachment;filename=output.csv');

/*

* output header row (if atleast one row exists)

*/

$row = mysql_fetch_assoc($result);

if ($row) {

echocsv(array_keys($row));

}

/*

* output data rows (if atleast one row exists)

*/

while ($row) {

echocsv($row);

$row = mysql_fetch_assoc($result);

}

/*

* echo the input array as csv data maintaining consistency with most CSV implementations

* - uses double-quotes as enclosure when necessary

* - uses double double-quotes to escape double-quotes

* - uses CRLF as a line separator

*/

function echocsv($fields)

{

$separator = '';

foreach ($fields as $field) {

if (preg_match('/\\r|\\n|,|"/', $field)) {

$field = '"' . str_replace('"', '""', $field) . '"';

}

echo $separator . $field;

$separator = ',';

}

echo "\r\n";

}?>
