   <h2>Heading</h2>
   <p>afsdfdfha adhfaksdhf adfhakhf adfhaskfdha fsahfkasdhfaasfdjhasdf ahdfkahsd</p>
   <p>afsdfdfha adhfaksdhf adfhakhf adfhaskfdha fsahfkasdhfaasfdjhasdf ahdfkahsd</p>
   <p>afsdfdfha adhfaksdhf adfhakhf adfhaskfdha fsahfkasdhfaasfdjhasdf ahdfkahsd</p>
   <p>yuoyuouoyuoyuyu oyuiouioyuioyuyiouyoiy youyoiyuioyuioyuyoiuyiuyiyuioyu yuyiu</p>
</div>
...
</html>

i want to extract all content in p and trying to insert whole stream into variable for to insert in database, i am using below these php codes 

<?php

include('simple_html_dom.php');

$url = 'http://www.example.com';

$html1=file_get_html($url);
$content=array();
foreach($html1->find('div.story-box p') as $e)
{
    $content=$e;
}
echo $content;
?>

why it is showing only last line... want to show all contents in p tag after assigning in one variable not $e

    If you're confused at printing arrays (just use print_r() by the way), just concatenate the strings:

    $contents = '';
foreach($html1->find('div.story-box p') as $e) {
    $contents .= $e;
    // or $contents .= $e . '<br/>';
}

echo $contents;
