Call to a member function find() on a non-object IN Simple_html_Dom

Question

I have a strange problem with this class. If I use a local file like test.html the code work perfectly without any errors but if I use remote page like google.com I got this error:

Call to a member function find() on a non-object

I don't understand why this happens nor hw to resolve it

Here is the code

<?php
include('simple_html_dom.php');
$id="hawkiq"; // any PSN id like : ashiqiraqi,duck360...etc
$url='http://www.yourgamercards.net/profile/'.$id; // url for profile page.

$html = new simple_html_dom();
$html->load_file($url);

$img = $html->find('img[alt='.$id.']',0); // Get User image .

foreach($html->find('span.about1me') as $e)
    $about= $e->outertext; // Get comment field .


foreach($html->find('td.tlevel') as $e)
    $s= $e->innertext;
    $level=strip_tags($s); // Get level 


foreach($html->find('td.platbg') as $e)
   $s= $e->innertext ;
    $platinum=strip_tags($s); // Get Platinum Trophies number .


foreach($html->find('td.goldbg') as $e)
    $s= $e->innertext ;
    $gold=strip_tags($s); // Get Gold Trophies number .


foreach($html->find('td.silverbg') as $e)
    $s= $e->innertext ;
    $silver=strip_tags($s); // Get Silver Trophies number .


foreach($html->find('td.bronzebg') as $e)
    $s= $e->innertext ;
    $bronze=strip_tags($s); // Get Bronze Trophies number .


foreach($html->find('td.totaltrophies') as $e)
    $s= $e->innertext ;
    $total=strip_tags($s); // Get Total trophies

    // Under construction :) .

// foreach($html->find('p.statsbottomcard') as $e)
    // $s= $e->innertext ;
    // $s=strip_tags($s);
    // echo $s;


    // Table for showing the results .

Answer 1

That error basically means you're trying to call find() on $html->find but $html is not the object

 <?php
include('simple_html_dom.php');
$id="hawkiq"; // any PSN id like : ashiqiraqi,duck360...etc
$url='http://www.yourgamercards.net/profile/'.$id; // url for profile page.

$html = new simple_html_dom();
  //here $html is now object if this will not work use $html = file_get_html($url); this will work for you surely
$html = $html->load_file($url);

$img = $html->find('img[alt='.$id.']',0); // Get User image .

foreach($html->find('span.about1me') as $e)
$about= $e->outertext; // Get comment field .


foreach($html->find('td.tlevel') as $e)
    $s= $e->innertext;
$level=strip_tags($s); // Get level 


foreach($html->find('td.platbg') as $e)
   $s= $e->innertext ;
    $platinum=strip_tags($s); // Get Platinum Trophies number .


foreach($html->find('td.goldbg') as $e)
    $s= $e->innertext ;
    $gold=strip_tags($s); // Get Gold Trophies number .


foreach($html->find('td.silverbg') as $e)
    $s= $e->innertext ;
    $silver=strip_tags($s); // Get Silver Trophies number .


foreach($html->find('td.bronzebg') as $e)
    $s= $e->innertext ;
    $bronze=strip_tags($s); // Get Bronze Trophies number .


foreach($html->find('td.totaltrophies') as $e)
    $s= $e->innertext ;
    $total=strip_tags($s); // Get Total trophies

    // Under construction :) .

 // foreach($html->find('p.statsbottomcard') as $e)
    // $s= $e->innertext ;
    // $s=strip_tags($s);
    // echo $s;

Answer 2

You don't need to assign the return value of the load_file() method to variable. The following code should work just fine

$html = new simple_html_dom();
$html->load_file($url); // No need to assign the return value to a variable, instead just use $html as you normally would.
// Rest of the code here...
