PHP - 访问SimpleXML :: xpath函数数组的第一个索引

Question

I am using SimpleXML to get an element of an XML object specified by tag name and attribute... as follows:

$result = $xml->xpath('Stat[@Type="Venue"]');
$venue  = $result[0];

This works fine.

However... the following shortening gives me an error

$venue = $xml->xpath('Stat[@Type="Venue"]')[0];

PHP Parse error:  syntax error, unexpected '[' in /var/www/handler.php on line 10

I've got to be being stupid.... but I cannot seem to figure this out.

Answer 1

You can't use an array like that. You need to pass it to a variable like so

$venue = $xml->xpath('Stat[@Type="Venue"]');
echo $venue[0];

I think in PHP 5.4 you will have the ability to access array from objects, but don't quote me on that.

Edit: Sorry about that, I copied and pasted the code from the OP. [0] slipped from my radar!
