This code return an error500 and have no clue why
<?php
$url = "https://www.idownloadblog.com/tag/iphone/feed"; // url to parse
$rss = simplexml_load_file($url); // XML parser
// RSS items loop
echo $rss;
?>

Becuase simplexml_load_file is to load a file not an URL

I am trying to restore my old site which was built on PHP 5.6;
the following code is causing a 500 Error It has something to do with the session_start however I don't know how I can fix this to work.
Please could someone take a look and find a possible solution.
<?php
session_start();
include('_config/logged-out.php');
$login = clean($_GET[login]);
if(isset($_SESSION[usr_name]) && isset($_SESSION[usr_level]) && login!=logout) echo('<meta http-equiv="refresh" content="0;url=https://example.com" />'); else { } ?>

getting this php fatal error on this line when try apply theme
case('homeimage_texts'):
if(!empty(Params::getParam('homeimage'))){
foreach(Params::getParam('homeimage',false,false,false) as $key => $value){
osc_set_preference($key,trim($value),'osclasswizards_theme');
}
}
osc_add_flash_ok_message(__('Banner settings updated correctly', OSCLASSWIZARDS_THEME_FOLDER), 'admin');
osc_redirect_to(osc_admin_render_theme_url('oc-content/themes/'.OSCLASSWIZARDS_THEME_FOLDER.'/admin/settings.php#banner'));
break;
It looks like a PHP version issue. I you are using PHP 5.3 or below you may get this error message.

I am trying to put this line of code:
echo $row['url'];
between the quotations in this line of code:
$data = file_get_contents ("");
I have a link saved in my database which I want to be displayed between those brackets, but I keep getting syntax errors whatever way I try it. Is this possible or am I being stupid?
try that :
$data = file_get_contents ($row['url']);
