示例 #1 SplFileObject::fputcsv() example
<?php
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
$file = new SplFileObject('file.csv', 'w');
foreach ($list as $fields) {
$file->fputcsv($fields);
}
?>
The above example will write the following to file.csv
:
aaa,bbb,ccc,dddd 123,456,789 """aaa""","""bbb"""
