Answer 1

<?
$array = explode("\n", file_get_contents('fileName.txt'));

foreach($array as $url){

         $ch = curl_init(); 

        // set url 
        curl_setopt($ch, CURLOPT_URL, "example.com"); 

        //return the transfer as a string 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

        // $output contains the output string 
        $output = curl_exec($ch); 

        // close curl resource to free up system resources 
        curl_close($ch); 

        $result[] = $output;  

}
?>

finally 数组 $result 包含文本文件中链接的所有 html

Answer 2

对 url 做一个爆炸，例如： $urls = explode ('\n', urlstring)

现在您可以遍历 url 数组。
