Question

我需要一些代码的帮助。我正在处理我俱乐部的客户名单，我可以提取电子邮件地址并将其打印在屏幕上，我只是不能将它们写入txt。这是代码：

<?php if ( $_POST ){ 
function extract_emails($str)
{
    $regexp = '/([a-z0-9_\.\-])+\@(([a-z0-9\-])+\.)+([a-z0-9]{2,4})+/i';
    preg_match_all($regexp, $str, $m);
    return isset($m[0]) ? $m[0] : array();
} 
$xurl = $_POST['testo'];// THERE IS AN INPUT FIELD
$doc = new DOMDocument();
@$doc->loadHTMLFile($xurl);
$xpath = new DOMXpath($doc);
$wpage = $xpath->query('//body[@*]');
print_r(extract_emails($wpage->item(0)->nodeValue));
$scrivi=fopen("emails.txt","a");
fwrite($scrivi,NEED SOMETHING HERE."\n");
fclose($scrivi); 
}
?>

我每次尝试我在文件中找到的唯一输出是＃34; Array＆＃34;。

[解决] 谢谢@jDo，我用这种方式解决了它：

$mail = (extract_emails($wpage->item(0)->nodeValue));
$result = var_export($mail, true);
echo $result ;
$scrivi=fopen("emails.txt","a");
fwrite($scrivi,$result."\n");
fclose($scrivi);

提取数据后写入文件
