范例

Example #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"""

This method is available in PHP 5.4 and it is just a wrapper over php.net/fputcsv.
