打开CSV文件以追加(fopen
Docs):
$handle = fopen("test.csv", "a");
然后添加您的行(fputcsv
Docs):
fputcsv($handle, $line); # $line is an array of string values here
然后关闭手柄(fclose
Docs):
fclose($handle);
我希望这有用。

您可以为文件使用面向对象的接口类 - SplFileObject http://php.net/manual/en/splfileobject.fputcsv.php(PHP 5> = 5.4.0)
$file = new SplFileObject('file.csv', 'a');
$file->fputcsv(array('aaa', 'bbb', 'ccc', 'dddd'));
$file = null;

此解决方案适用于我:
<?php
$list = array
(
'Peter,Griffin,Oslo,Norway',
'Glenn,Quagmire,Oslo,Norway',
);
$file = fopen('contacts.csv','a'); // 'a' for append to file - created if doesn't exit
foreach ($list as $line)
{
fputcsv($file,explode(',',$line));
}
fclose($file);
?>

如果您希望每个拆分文件保留原始标题;这是hakre答案的修改版本:
$inputFile = './users.csv'; // the source file to split
$outputFile = 'users_split'; // this will be appended with a number and .csv e.g. users_split1.csv
$splitSize = 10; // how many rows per split file you want
$in = fopen($inputFile, 'r');
$headers = fgets($in); // get the headers of the original file for insert into split files
// No need to touch below this line..
$rowCount = 0;
$fileCount = 1;
while (!feof($in)) {
if (($rowCount % $splitSize) == 0) {
if ($rowCount > 0) {
fclose($out);
}
$out = fopen($outputFile . $fileCount++ . '.csv', 'w');
fputcsv($out, explode(',', $headers));
}
$data = fgetcsv($in);
if ($data)
fputcsv($out, $data);
$rowCount++;
}
fclose($out);
