Question

I have this xml response to which I will do a

foreach($response->entry->item as $data)

but $data contains more arrays (20) than I need (18). So I tried doing array_slice but as you know it won’t work.

What other solutions could I try?

You could try restricting the result set from the data you select from your xml via xpath.

$string = <<<XML
<?xml version='1.0'?>
    <document>
        <item id="1" />
        <item id="2" />
        <item id="3" />
        <item id="4" />
        <item id="5" />
        <item id="6" />
    </document>
XML;

$xml = simplexml_load_string($string);
var_dump($xml->xpath("//item[@id>2 and @id<5]")) // Prints the two nodes matching the condition from the xpath

As was suggested from the comments you could also just loop over the array with for instead of foreach and restrict the number of iterations.
