php动态元描述为空

Question

While executing this code from a webservice, the title and keywords are shown in the meta tags as expected. The description stays empty though. How do I put dynamic array content from $array in the description? Ps eg $array[3] won't work either.

$array = $result->AAAResult->AAA->A;

$teller = count($array);

$titeltekst = "{$teller} quantity: $r";


$doc =& JFactory::getDocument();
$options = $doc->getHeadData();

$options['title'] = $titeltekst;
$options['metaTags']['standard']['keywords'] = "keywords - test";
$options['metaTags']['standard']['description'] = $array;

$doc->setHeadData($options);

Answer 1

You wont be able to assign an array directly to anything that expects a string, but you can use implode assuming that all the values are also strings.

$string = implode(', ', $array);
