I'm trying to extract the price from the bellow html page/link using php cURL and preg_match . Basically I'm expecting for this code to output 4,550 but for some reasons I get
Notice: Undefined offset: 1 in C:\wamp\www\test.php on line 22
I think that the pattern is correct because if I put the html itself in a variable and escape the "" it works ! .
Also if I output (echo $result;) it displays the html properly grabbed from foxtons website so I just can't figure it out why the whole thing doesn't work . I need to make this work and also I would appreciate if you would tell me why is that notice generated and why my current script doesn't work.
$url = "http://www.foxtons.co.uk/search?bedrooms_from=0&property_id=727717";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_exec($ch);
curl_close($ch);
$result2 = str_replace('"', '\"', $result);
$tagname1= ");<\/script
";
$tagname2= "<\/noscript
per month<\/a";
$pattern = "/$tagname1(.*?)$tagname2/";
preg_match($pattern, $result, $matches);
$prices = $matches[1];
print_r($prices);
?
