执行、获取远程代码返回:file_get_contents 超时处理的问题详解

复制代码 代码如下:

$url = "http://zhoz.com/zhoz.php";
$ctx = stream_context_create(array(
‘http' => array(‘timeout' => 10)
)
);
$result = @file_get_contents($url, 0, $ctx);
if($result){
var_dump($result);
}else{
echo " Buffer is empty";
}
?>

复制代码 代码如下:

$url = "http://zhoz.com/zhoz.php";
try {
echo date(‘Y-m-d h:i:s');
echo "";
//$buffer = file_get_contents($url);
$buffer = zhoz_get_contents($url);
echo date(‘Y-m-d h:i:s');
if(emptyempty($buffer)) {
echo " Buffer is empty";
} else {
echo " Buffer is not empty";
}
} catch(Exception $e) {
echo "error ";
}
function zhoz_get_contents($url, $second = 5) {
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch,CURLOPT_TIMEOUT,$second);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
$content = curl_exec($ch);
curl_close($ch);
return $content;
}
?>

复制代码 代码如下:

function vita_get_url_content($url) {
if(function_exists(‘file_get_contents')) {
$file_contents = file_get_contents($url);
} else {
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
}
return $file_contents;
}
?>
