$ch=curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Your application name');
$query = curl_exec($ch);
$errorCode = curl_errno($ch);
curl_close($ch);
$array = (array) simplexml_load_string($query);
//echo '<pre>';
//print_r($array);

$TotalResults = $array['Meta']->TotalResults;
echo "function is correct";
}
}
when i call this fun
echo $obj1->TotalResults;
this gives error to me. please help me and modify my code.

Answer 1

You incorrectly used member variables:
class myclass{
public $TotalResults; // <-- added member variable
public function getresults{
$url = 'http://www.slideshare.net/api/2/search_slideshows?q=google';
echo $url;
$ch=curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Your application name');
$query = curl_exec($ch);
$errorCode = curl_errno($ch);
curl_close($ch);
$array = (array) simplexml_load_string($query);
//echo '<pre>';
//print_r($array);
$this->TotalResults = $array['Meta']->TotalResults; // <-- corrected
echo "function is correct";
}
}
and after you do $obj->getresults() (where $obj must be instantiated by $obj = new myclass(); before), the $obj->TotalResults should contain what you wanted.
Did it help?

Something like this :
<?php
class myclass {
public function getresults()
{
$url = 'http://www.slideshare.net/api/2/search_slideshows?q=google';
echo $url;
$ch=curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Your application name');
$query = curl_exec($ch);
$errorCode = curl_errno($ch);
curl_close($ch);
$array = (array) simplexml_load_string($query);
//echo '<pre>';
//print_r($array);
public $TotalResults;
$TotalResults = $array['Meta']->TotalResults;
echo "function is correct";
}
}
$obj = new myclass;
echo $obj1->getresults();
