Closed 9 years ago.
Okay so I've been working on this little script which is bascially scrapping a page from ted.com everything works as i want it to (meaning I can print out all values that I am interested in), The problem is for some reason i get these warning when running the scraper but am unsure as to why as the values the notice / warning occer on are printed out properly
PHP Warning: dom_import_simplexml() expects parameter 1 to be object, null given in /var/www/ted/import_ted.php on line 23
PHP Notice: Trying to get property of non-object in /var/www/ted/import_ted.php on line 23
PHP Notice: Undefined offset: 1 in /var/www/ted/import_ted.php on line 25
PHP Notice: Trying to get property of non-object in /var/www/ted/import_ted.php on line 27
and this is my actually php script (I've commented lines where warning's and Notice)
<?php
$mysqli = mysqli_connect("localhost", "user", "password", "database");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$html = file_get_contents('http://www.ted.com/talks/quick-list?sort=date&order=desc');
$doc = new DOMDocument();
$doc->loadHTML($html);
$sxml = simplexml_import_dom($doc);
$rows = $sxml->xpath('//tr');
$description="not_available";
$ted_link="none";
$i=0;
//$stmt = $mysqli->prepare("INSERT INTO `ted` VALUES( ?, ?, ?, ?, ?, ?, ?)");
foreach($rows as $row) {
$video = Array();
$video['pub_date']= $row->td[0];
$video['event'] = $row->td[1];
$sec_temp = explode(":" , dom_import_simplexml($row->td[2])->textContent );//line23
$video['speaker'] = $sec_temp[0];
$video['title'] = $sec_temp[1]; //line 25
$video['duration'] = $row->td[3];
$video['link'] = $row->td[4]->a[2]['href']; //line27
print( "\n line Number: " . $i . "title: " . $video['title']);
print ("link: " .$video['link']);
if($i != 0){
// $stmt->bind_param("sssssss", $video['event'], $video['speaker'], $video['title'], $description, $ted_link, $video['link'], $description, $video['pub_date'] );
// $stmt->execute();
}
$i++;
}
// $stmt->close();
?>
Okay so Like I said Everything prints out what I am expecting including $video['title'] which generates an undefined offset for some reason. The problem is until I can make these variable "objects" I cannnot bind them as parameters to mysqli query. However I can't seem to figure out how to do this?
also incase relevent here is a snippet of a table row incase this is the problem (which I do not think it is )
<tr>
<td>Jun 2013</td>
<td>TEDGlobal 2013</td>
<td>Manalal-Sharif: A Saudi woman who dared to drive </td>
<td>14:16</td>
<td>Low | Regular | High</td>
</tr>
Note also I have tried using settype($var, "object") before binding with no luckeither (though reurned true)
Anyways any help with how I can get this to work would be greatly appreciated!
