XML> PHP仅在源代码中

Question

I have a slight issue whereby the API I'm using for part of my service uses a rsp stat to handle the success / error messages in XML.

So we use a form to post it data and it returns the data like the following example:

<rsp stat="ok"> 
    <success msg="accepted" transactionid="505eeb9c43969d4919c0a6b3f7a4dfbb" messageid="a92eff8d65cf48e9c6e96702a7b07400"/> 
</rsp>

The following is most of the script used :

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
     // ToDo: Replace the placeholders in brackets with your data.
     // For example - curl_setopt($ch, CURLOPT_UsERPWD, 'SMSUser:PassW0rD#');
curl_setopt($ch, CURLOPT_USERPWD, '');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
$xml = curl_exec($ch);
if (curl_error($ch)) {
print "ERROR ". curl_error($ch) ."

";
} 
curl_close($ch); 
print_r($xml);

The only problem is that when it is parsed and displayed via the print_r command , it only displays via source code for some strange reason and we have no idea how to display it via the page

Basically we would like a system whereby if rsp stat="ok" then "Sent" else "unsent".

Answer 1

Well, a simple way could be:

if (strpos($xml, 'stat="ok"') !== false) {
    echo "sent";
} else {
    echo "unsent";
}

This would replace print($xml);.
