php csv操作

csv的写入数据:

1. $data = array(
2. array('qq号','登录时间','名称'),
3. array('123456','2012-08-21 15:21:10'.chr(1),'我是来测试的'),
4. array('56788','2012-08-21 18:21:20 '.chr(1),'test测试数据'),
5. array('321789','2012-08-21 11:21:25 '.chr(1),'HELLO')
6. );
7. $filename = "./file/test.csv";
8. if( !file_exists( $filename ) ){
9. file_put_contents($filename, '');
10. }
11. $file = fopen($filename, 'w');
12. foreach ( $data as $val ){
13. if( false === fputcsv($file, $val) ){
14. die('写入数据失败');
15. }
16. }
17. fclose($file);

$data = array(
	array('qq号','登录时间','名称'),
	array('123456','2012-08-21 15:21:10'.chr(1),'我是来测试的'),
	array('56788','2012-08-21 18:21:20 '.chr(1),'test测试数据'),
	array('321789','2012-08-21 11:21:25 '.chr(1),'HELLO')
);
$filename = "./file/test.csv";
if( !file_exists( $filename ) ){
	file_put_contents($filename, '');
}
$file = fopen($filename, 'w');
foreach ( $data as $val ){
	if( false === fputcsv($file, $val) ){
		die('写入数据失败');
	}
}
fclose($file);

在写入到csv的时候我的日期格式出现了问题,只显示格式为:2011/06/05 12:02。导致我的秒数不存在了,所以在时间的后面都要加上chr(1)来得到正确的格式

csv读数据:

1. $file = fopen($filename, 'w') or die('打开文件失败');
2. //读数据
3. $file = fopen($filename, 'r');
4. while ( $val = fgetcsv($file) ){
5. print_r($val);
6. }
7. fclose($file);

$file = fopen($filename, 'w') or die('打开文件失败');
//读数据
$file =  fopen($filename, 'r');
while ( $val = fgetcsv($file) ){
	print_r($val);
}
fclose($file);

csv的下载:

1. $data = array(
2. array('qq号','登录时间','名称'),
3. array('123456','2012-08-21 15:21:10'.chr(1),'我是来测试的'),
4. array('56788','2012-08-21 18:21:20 '.chr(1),'test测试数据'),
5. array('321789','2012-08-21 11:21:25 '.chr(1),'HELLO')
6. );
7. //下载功能
8. $date = time();
9. header("Content-Type: text/csv");
10. header("Content-Disposition: attachment; filename=".$date.".csv");
11. header('Cache-Control:must-revalidate,post-check=0,pre-check=0');
12. header('Expires:0');
13. header('Pragma:public');
14. foreach ( $data as $val ){
15. echo implode(",", $val)."\n";
16. }

18. <?php
    $filename = "./creattest.csv";
    //读数据
    $file = fopen($filename, 'r');
    $prex = "linpre";
    while ( $val = fgetcsv($file) ){
    print_r($val);
    echo "<hr/>";
    $val_list[] = $val;
    }
    $val_list[0][0] = $prex.$val_list[0][0];
    $val_list[1][0] = $prex.$val_list[1][0];
    echo $val_list[0][0]."------------";
    $file = fopen($filename, 'w');
    foreach ( $val_list as $list ){
    if( false === fputcsv($file, $list) ){
    die('写入数据失败');
