複製代碼 代碼如下:
function remote($urls, $name = '', $path = '', $dir = './images/') {
if (!is_array($urls) or count($urls) == 0) {
return false;
}
dmkdir($dir);
$curl = $text = array();
foreach($urls as $k => $v) {
if (!empty($v) && preg_match("~^http~i", $v)) {
$nurl[$k] = trim(str_replace(' ', "%20", $v));
$curl[$k] = curl_init($nurl[$k]);
curl_setopt($curl[$k], CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
curl_setopt($curl[$k], CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl[$k], CURLOPT_HEADER, 0);
curl_setopt($curl[$k], CURLOPT_CONNECTTIMEOUT, 20);
if(!isset($handle)){
$handle = curl_multi_init();
}
curl_multi_add_handle($handle, $curl[$k]);
}
continue ;
}
$active = null;
do{
$mrc = @curl_multi_exec($handle, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
while ($active && $mrc == CURLM_OK) {
if (curl_multi_select($handle) != -1) {
do {

}
}
foreach ($curl as $k => $v) {
if (curl_error($curl[$k]) == "") {
if ($k == 0) {
$fname[$k] = strtolower($name . '.' . pathinfo($urls[$k], PATHINFO_EXTENSION));
