PHP function help

Question

This is the function:

function NewsDat($url="http://www.url.com/dat/news.dat", $max=5){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $curlresult = curl_exec($ch);

    $posts = explode("\n", $curlresult); //chop it up by carriage return
    unset($curlresult);

    $num=0; 
    $result=array();
    foreach($posts as $post){
        $result[] = explode("::", $post);
        $num++;
        if($num>$max-1){
            break;
        }
    }
    return $result; 
}

var_dump(NewsDat());

Which returns:

array(5) { [0]=>  array(14) { [0]=>  string(10) "1183443434" [1]=>  string(1) "R" [2]=>  string(46) "Here is some text"...

I need to echo: 1183443434 and Here is some text...

Can anyone help?

Anyone know how I can sort the array to get the last items in the DAT file? — CLiown

Basic array handling?

$result = NewsDat();
echo $result[0][0]; //holds "1183443434"
echo $result[0][2]; //holds "Here is some text"

But I don't know if the values are always at this positions when you run your function.

Well as NewsDat return an array of arrays, if you need this two fields on each lines, this should do the trick:

$news = NewsDat();

foreach($news as $single_new)
{
    echo $single_new[0] . " - " . $single_new[2] . "\n";
}

If you only need these two fields, just:

$news = NewsDat();
$field1 = $news[0][0];
$field2 = $news[0][2];
echo $field1 . " - " . $field2 . "\n";
