php foreach loop with urls from file - php

Question

I am trying to the status of urls which are stored in a text file
in my code i have:
$filestatus = file("urlsmartins_status.txt");
foreach ($filestatus as $filestate){
$filestatusurl = (file_get_contents("$filestate"));
$filestatusurlxml = new SimpleXMLElement ($filestatusurl);
print_r ($filestatusurlxml);
}
in the urlsmartin_status.txt i have 5 urls written
http://172.27.73.5:8080/api/service/
http://172.27.73.6:8080/api/service/
http://172.27.73.7:8080/api/service/
http://172.27.73.8:8080/api/service/
But when i execute the code i have the following result
PHP Warning: file_get_contents(http://172.27.73.5:8080/api/service/
): failed to open stream: HTTP request failed! HTTP/1.1 404 OK
PHP Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in ...
Stack trace:
#0 /opt/rh/httpd24/root/var/www/html/pub/martin.php(56): SimpleXMLElement->__construct('')
#1 {main}
thrown in /opt/rh/httpd24/root/var/www/html/pub/martin.php on line 56
What am i missing here?
Thanks

Answer 1

the problem here is that the lines in your file are not "XML", hence SimpleXMLElement cannot be instantiated.
I get the same error like this:

Answer 2

I managed to fix it via
$filedata = file_get_contents('urlsmartins_status.txt');
$urls = explode("\n", trim($filedata));
foreach($urls as $key => $url) {
$filestatusurl = file_get_contents("$url");
$filestatusurlxml = new SimpleXMLElement ($filestatusurl);
print_r ($filestatusurlxml);
