xml content not parsing

I have created a function to get xml content and below is function to get xml content. curl is enabled on the server.XMl is validated on online xml validator tool.

function curlToGetXmlContent($url)
{
    $xml_file_url = $url;
    $curl = curl_init(); 
    // Setup curl. 
    curl_setopt($curl, CURLOPT_URL,"$xml_file_url"); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 0); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); 
    
    $xml_file = curl_exec($curl);
    $err = curl_error($curl);
    
    curl_close($curl);
    
    $xml = simplexml_load_string($xml_file_url );
    if ($err) { 
        echo "cURL Error:" . $err;
    } else {
        return $xml->item;
    }  
}

Call function in the content

  $xmlContent = curlToGetXmlContent("https://example.com/abc.xml");
  foreach ($xmlContent as $content) {
        $var = $content->id.''. $content->title;
  } 

below is the xml of abc.xml file

I am not getting content id and title and getting warning :

1. Warning: Attempt to read property "item" on bool in curlToGetXmlContent() 

I am not sure i missed and why i am getting warning with any data render in foreach

The issue seems to be with the way you are loading the XML content and processing it in the curlToGetXmlContent function. Instead of passing $xml_file_url to the simplexml_load_string function, you should pass $xml_file, which contains the actual XML content fetched using cURL. Additionally, you need to use simplexml_load_string instead of simplexml_load_string, as the former loads XML from a string, while the latter attempts to load the XML from a file.

Here's the updated version of your function:

function curlToGetXmlContent($url)
{
    $xml_file_url = $url;
    $curl = curl_init(); 
    // Setup curl. 
    curl_setopt($curl, CURLOPT_URL,"$xml_file_url"); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 0); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); 
    
    $xml_file = curl_exec($curl);
    $err = curl_error($curl);
    
    curl_close($curl);
    
    $xml = simplexml_load_string($xml_file); // Use $xml_file instead of $xml_file_url
    if ($err) { 
        echo "cURL Error:" . $err;
    } else {
        return $xml->item;
    }  
}

With this change, your curlToGetXmlContent function should now correctly load the XML content and return the item elements as expected.

One additional suggestion is to change the return statement to return all items as an array instead of just a single item, especially since you are using a foreach loop in your calling code. Here's the updated return statement:

Now, in your calling code, the foreach loop should work correctly and not produce the warning:

$xmlContent = curlToGetXmlContent("https://example.com/abc.xml");
foreach ($xmlContent as $content) {
    $var = $content->id . ' ' . $content->title;
    echo $var . "<br>"; // Assuming you want to print the id and title for each item
}

Output:

1 Example title, example.
2 Example title -1, example.
3 Example title -2, example.
4 Example title -3, example.
5 Example title -4, example.
6 Example title -5, example.
7 Example title -5, example.
8 Example title -7, example.
9 Example title -8, example.
10 Example title -9, example.
11 Example title -10, example.
12 Example title -11, example.
13 Example title -12, example.
14 Example title -13, example.
15 Example title -14, example.
16 Example title -15, example.
17 Example title -16, example.
18 Example title -17, example.
19 Example title -18, example.
20 Example title -19, example.
21 Example title -20, example.
22 Example title -21, example.
23 Example title -22, example.
25 Example title -23, example.
26 Example title -24, example.
