How PHP determines whether it is connected to the network, PHP determines whether it is connected to the network

The example in this article describes how PHP determines whether it is connected to the network. Share it with everyone for your reference. The specific implementation method is as follows:

First write a function

function varify_url($url){ 
$check = @fopen($url,"r"); 
if($check){ 
 $status = true; 
}else{ 
 $status = false; 
}  
return $status; 
}

Then just call it directly where needed

$url = "http://www.baidu.com"; 
if(varify_url($url)){ 
 echo "<div>Congratulation ! Your URL <a href=$url>$url</a> : is <b>valid </b></div>"; 
}else{ 
 echo "<div>Error ! Your URL : <a href=$url>$url</a> is <b>invalid </b></div>"; 
}

I hope this article will be helpful to everyone’s PHP programming design.
