PHP curl question

[Huynh]

Why does this code hang? Comment out the break statement and it works fine, but only for the first item in the $sitelist array.I know about PHP curl's multisite feature, but I am not interested in fetching files in parallel.Code snippet: \[code\]$sitelist = array(11204,11509,20602,21601,22003,22704,23106,23303,23402,23422,23427,30215,30220,30234,30282,30302,30304,30905,40110,40122,40204,40406,40624,50144,50304,50408,50409,50801,50807,50904,51001,51502,52212,52219,52233,52604,52606,60703,61020,61022,61024,61502,61602,61901,61905,61909,62102,62114,62803,72301,73503,73801,74903);$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;}\[/code\]
