深入php函数file_get_contents超时处理的方法详解_PHP
这里需要注意:set_time_limit只是设置你的PHP程序的超时时间,而不是file_get_contents函数读取URL的超时时间。真正的修改 file_get_contents延时可以用resource $context的timeout参数:
复制代码 代码如下:
$opts = array(
'http'=>array(
'method'=>"GET",
'timeout'=>60,
) );
$context = stream_context_create($opts); $html =file_get_contents('http://www.example.com', false, $context);
二、一次有延时的话那就多试几次
有时候失败是因为网络等因素造成,没有解决办法,但是可以修改程序,失败时重试几次,仍然失败就放弃,因为file_get_contents()如果失败将返回 FALSE,所以可以下面这样编写代码:
$cnt=0;
while($cnt 以上方法对付超时已经OK了。
有人发现了'method'=>”GET”,GET也可以设置成post,函数如下
复制代码 代码如下:
function Post($url, $post = null)
{
$context = array();
if (is_array($post)) {
ksort($post);
$context['http'] = array (
'timeout'=>60,
'method' => 'POST',
'content' => http_build_query($post, '', '&'),
);
}
return file_get_contents($url, false, stream_context_create($context));
}
$data = array (
'name' => 'test',
'email' => 'test@gmail.com',
'submit' => 'submit',
);
echo Post('http://www.example.com', $data);
