[Fputcsv() Is Writing To My File But Erasing The Previous Data]

HI all,

I am using php code to write into my csv file , its able to write successfully but every time i run my code the older data is lost and csv file is left with data which only the current run contains.

I used this

 

<?

$list = array (

array('aaa', 'bbb', 'ccc', 'dddd'),

array('123', '456', '789'),

array('"aaa"', '"bbb"')

);

 

$fp = fopen('test.txt', 'w');

 

foreach ($list as $fields) {

fputcsv($fp, $fields);

}

 

fclose($fp);

?>

 

Any suggestions???

Many thanks .
