Question

I´m trying to get familiar with the PHP SimpleXML function and would appreciate a little help. I´m fetching updates to a Call Center received calls and adding only new received calls from the current date to a combined string. I need to run this every 10 minutes via cronjob and let the combined string grow over the day.

Here is the XML I´m working with:

<?xml version="1.0" encoding="ISO-8859-1"?>
<received>
  <call>
    <countryCode>46</countryCode>
    <phoneNumber>4386541313</phoneNumber>
    <name>Unavailable</name>
    <time>2012-12-05T08:41:29.863Z</time>
  </call>
  ...
</received>

What I would like to do is extract all phoneNumber and time elements with a foreach loop and add them as a string to a combined comma seperated string.

The string would looks like this:

From the above xml example 4386541313-2012-12-05T08:41:29.863Z
Or phoneNumber-time

The comma seperated string would look like this:

4386541313-2012-12-05T08:41:29.863Z,1186111311-2012-12-03T08:11:21.561Z,...

But I only want to add the string to the comma seperated list IF the timestamp is from the current date.

Here is what I have, but it´s not much and I´m not sure if this is the best way to do what I want:

$date_today = date('Y-m-d');
$combined_string = "4386541313-2012-12-05T08:41:29.863Z,1186111311-2012-12-03T08:11:21.561Z";

$received = simplexml_load_file('thexmlfile.xml');

foreach ($received->call->phoneNumber as $phoneNumber) { 
    foreach ($received->call->time as $time) {

        $new_call = $phoneNumber."-".$time;

        if(strpos($new_call,$date_today) !== false)
                    {
            $combined_string = $new_call.",".$combined_string;
        } 
    }
}

The above returns a blank page with no errors.

Might want to try something like:

foreach ($received->call as $call) { 
    $new_call = $call->phoneNumber . "-" . $call->time;
    if(strpos($new_call,$date_today) !== false) {
        $combined_string = $new_call.",".$combined_string;
    } 
}
