Solution to PHP reading remote data timeout

How does PHP solve the timeout problem of reading remote data? This article mainly introduces the solution to the timeout of reading remote data by the PHP file_get_contents function. This article directly gives the solution code. I hope to be helpful.

The file_get_contents function often fails to read remote data when the network condition is poor.
The solution is as follows:

/*设置超时配合失败之后尝试多次读取，效果比原先好很多*/
$url = 'http://www.jb51.net';
          $opts = array( 
           'http'=>array( 
          'method'=>"GET", 
          'timeout'=>1, //设置超时
  ) 
 ); 
 $context = stream_context_create($opts); 
 $contents = @file_get_contents($url,false,$context); 
?>
