PHP指定DOMDocument的超时持续时间？

Question

I have a code that will scrap some data from a website using PHP DomDocument. However, I would like to specify the timeout duration. Is there any way to do so?

The code that I have is something like this:

<?php 
$grep = new DoMDocument(); 
@$grep->loadHTMLFile("http://www.example.com"); 
$finder = new DomXPath($grep); 
$class = "Cat"; 
$nodes = $finder->query("//*[contains(@class, '$class')]"); 

foreach ($nodes as $node) 
{ 

//coding    
}   
?> 

Thanks!

Alternatively, you could use fil_get_contents() and set there the timeout duration, then feeding the return values into the DOMDocument class:

$context = stream_context_create(array(
    'http' => array('timeout' => 60), // 60 seconds
));
$html_page = file_get_contents('http://www.example.com', false, $context);

$grep = new DoMDocument(); 
@$grep->loadHTML($html_page); 
$finder = new DomXPath($grep); 
$class = "Cat"; 
$nodes = $finder->query("//*[contains(@class, '$class')]");
