How does php retrieve valid URLs in the text?
I do a 24-hour random jump program, first of all, the URL is written into a txt document, one by one. Then use php to read the URL in the txt, take out the accessible URL, skip if there is an inaccessible URL, rule it out and continue to select!
the current method is relatively simple to implement loop acquisition
<?php
//txt
$data=file_get_contents("test.txt");
//
$data_url=explode("\r\n",$data);
//
$data_num = rand(0, count($data_url)-1);
//
$url = $data_url[$data_num];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_exec($ch);
$curl_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
//
if ($curl_code == 200) {
//cookie
if (isset($_COOKIE["data"])){
$tzUrl=$_COOKIE["data"];
echo ":".$tzUrl;
//header ("Location: $tzUrl");
}else{
//
//header ("Location: $data_url[$data_num]");
$value = $data_url[$data_num];
//setcookie("data",$value, time()+3600/60/6);
//24
setcookie("data",$value, time()+3600*24);
};
//echo ":" . $curl_code;
}else {
//echo ":" . $curl_code;
}
the boss of the program will take a look at it, and you will be paid a reward

PHP: getallheaders-Manual- http://php.net/manual/zh/func.
this is a class library that encapsulates TXT files as a database to read and write TXT files, in which you can convert TXT text into an array, and then traverse the array to request a URL. Reference source code for you.

the change of the landlord should be able to use it.
add it on your basis. I hope it will be useful
