note 87342 added to function.curl-setopt

There is no CURLOPT_MAXFILESIZE in the PHP module but it's function only works with Content-Length headers anyway. There are two ways of checking download sizes, one is after the download is complete using filesize(), the other is as the download is running allowing you to terminate before wasting time and disk space. <? $GLOBALS['file_size'] = 0; $GLOBALS['max_file_size'] = 1024 * 1024; function on_curl_header($ch, $header) { $trimmed = rtrim($header); if (preg_match('/^Content-Length: (\d+)$/', $trimmed, $matches)) { $file_size = $matches[1]; if ($file_size > $GLOBALS['max_file_size']) { // handle error here. } } return strlen($header); } function on_curl_write($ch, $data) { $bytes = strlen($data); $GLOBALS['file_size'] += $bytes; if ($GLOBALS['file_size'] > $GLOBALS['max_file_size']) { // handle error here. } return $bytes; } $ch = curl_init(); $options = array(CURLOPT_URL => 'http://www.php.net/', CURLOPT_HEADER => false, CURLOPT_HEADERFUNCTION => 'on_curl_header', CURLOPT_WRITEFUNCTION => 'on_curl_write'); curl_setopt_array($ch, $options); curl_exec($ch); // ... ?> ---- Server IP: 203.169.164.81 Probable Submitter: 220.232.210.142 ---- Manual Page -- http://www.php.net/manual/en/function.curl-setopt.php Edit -- https://master.php.net/note/edit/87342 Del: integrated -- https://master.php.net/note/delete/87342/integrated Del: useless -- https://master.php.net/note/delete/87342/useless Del: bad code -- https://master.php.net/note/delete/87342/bad+code Del: spam -- https://master.php.net/note/delete/87342/spam Del: non-english -- https://master.php.net/note/delete/87342/non-english Del: in docs -- https://master.php.net/note/delete/87342/in+docs Del: other reasons-- https://master.php.net/note/delete/87342 Reject -- https://master.php.net/note/reject/87342 Search -- https://master.php.net/manage/user-notes.php
