php cURL.

2 Cevap php

Ben php cURL ve preg_match kullanarak feryat html sayfası / linkinden fiyatı ayıklamak çalışıyorum. Temelde çıkış 4550 bu kod için ama olsun, bazı nedenlerle bekliyorum

 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 ($ fiyatları);

?>

Don't use REGEX to parse html, PHP Simple HTML DOM Parser gibi, bunun yerine bir html dom ayrıştırıcı kullanmak

include("simple_html_dom.php") ;

$html = file_get_html("http://www.foxtons.co.uk/search?bedrooms_from=0&property_id=727717");

foreach($html->find('noscript') as $noscript)
{

    echo $noscript->innertext."<br>";
}
