PHP Curl question

Question

Pourquoi ce code se bloquer? Commentez l'instruction break et cela fonctionne correctement, mais uniquement pour le premier élément du tableau $ sitelist.

Je connais la fonction multisite de PHP curl, mais je ne suis pas intéressé par l'extraction de fichiers en parallèle.

extrait de code:

$sitelist = array(11204,11509,20602,21601,22003,22704,23106,23303,23402,23422,23427,30215,30220,30234,30282,30302,30304,30905,40110,40122,40204,40406,40624,50144,50304,50408,50409,50801,50807,50904,51001,51502,52212,52219,52233,52604,52606,60703,61020,61022,61024,61502,61602,61901,61905,61909,62102,62114,62803,72301,73503,73801,74903); 

$actliste = array(); 
$recherche =' <a name="JOUR1">'; 

foreach ($sitelist as $site) 
{ 

    # obtain the data at each site 

    // Create a curl handle 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

    $url = sprintf("http://www.cehq.gouv.qc.ca/Suivihydro/tableau.asp?NoStation=0%s", $site); 
    //echo $url . '<br />'; 

    curl_setopt($ch, CURLOPT_URL, $url); 

    $output = curl_exec($ch); // Run curl 
    if ($output === FALSE) 
    { 
     echo 'Curl error retrieving: ' . $url. ' ' . curl_error($ch) . '<br />'; 
     exit; 
    } 

    // Set up a way to detect HTTP anomolies. An HTTP code of 200 is expected 
    $info = curl_getinfo($ch); 
    if ($info['http_code'] <> 200) 
    { 
     echo sprintf("HTTP error code %s returned\n", $info['http_code']); 
     echo strip_tags(sprintf("Message received: %s\n", $output)); 
     exit($info['http_code']); // The HTTP error code is returned so it can be grabbed programatically 
    } 

    echo '0' . $site; 

    // Find: first <td width="33%" until the first </tr> 
    $start_loc = strpos($output, '<td width="33%"'); 
    $end_loc = strpos($output, '</tr>', $start_loc); 
    $substring = substr($output,$start_loc, $end_loc - $start_loc); // Contains all the data we need 

    // Get day 
    $day_pos = strpos($substring, '<font face="Verdana" size="2">') + 30; 
    //echo "Substring = " . $substring . '<br />'; 
    $day = substr($substring,$day_pos,10); // 2010-01-08 
    echo ' ' . $day; 

    // Get time 
    $time_pos = strpos($substring,'<font face="Verdana" size="2">', $day_pos) + 30; 
    $time = substr($substring, $time_pos, 5); 
    echo ' ' . $time; 

    // Get measurement 
    $measurement_pos = strpos($substring,'<font face="Verdana" size="2">', $time_pos) + 30; 
    $measurement = substr($substring, $measurement_pos, 5); 
    echo ' ' . $measurement . '<br />'; 

    curl_close($ch); 
    echo 'Channel closed<br />'; 

    sleep(2); 
    echo 'Done sleeping'; 
    //break; 

}

Vous n'avez pas besoin la pause du tout, comme vous êtes déjà à la fin de la boucle foreach.

Pour ce qui est de savoir pourquoi il est suspendu, vous pouvez flush la sortie à la fin de chaque boucle. Où vous avez actuellement break, mettez flush().
