writing CVS file using array and dom document in php - php

Question

i am using this code to scrap the amazon.com
$ch = curl_init(); // create a new cURL resource
$url='http://www.amazon.com/s/ref=sr_pg_1?rh=n%3A133140011%2Ck%3Aenglish+literature&sort=paidsalesrank&keywords=english+literature&ie=UTF8&qid=1327432144';
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$data = curl_exec($ch); // grab URL and pass it to the browser
//echo $data; ok till now
curl_close($ch);
$dom = new DOMDocument();
#$dom->loadHTML($data); // avoid warnings
$xpath = new DOMXPath($dom);
//getting titles
$book_t = $xpath->query('//div[#class="title"]/a[#class="title"]');
foreach ($book_t as $tag) {
print_r(trim($tag->nodeValue));
echo '<br/>';
}
$author = $xpath->query('//div[#class="title"]/span[#class="ptBrand"]');
foreach ($author as $tag) {
echo '<br/>';
//print_r($tag->nodeValue);
$s=$tag->nodeValue;
print_r(str_replace('by ', '', $s));
echo '<br/>';
}

Answer 1

there's a function fputcsv ... you can use it like this:
<?php
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
$fp = fopen('file.csv', 'w');//your file csv
foreach ($list as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);
?>
each array in the array list will be a line in the csv file..
