Question

I have this code but it doesn't work. It show nothing.
<?php
$item = file_get_contents('https://www.googleapis.com/books/v1/volumes?q=Bowling Alone&maxResults=1');
$booktitle = (isset($item->volumeInfo->title) ? $item->volumeInfo->title : false);
$description = (isset($item->volumeInfo->description) ? $item->volumeInfo->description : false);
echo "<b>Title:</b> " . $booktitle;
echo "<b>Description:</b> " . $description;
?>
So, please help me fix it ! Also, this is any way to get content faster ? Thank you very much !

Answer 1

Make it url compatible, so no spaces in it. You also needed to add a foreach loop because incase of more results. And decode the json result into a object
$item = file_get_contents('https://www.googleapis.com/books/v1/volumes?q=Bowling%20Alone&maxResults=1');
$item = json_decode($item);
foreach ($item->items as $item) {
$booktitle = (isset($item->volumesInfo->title) ? $item->volumeInfo->title : false);
$description = (isset($item->volumeInfo->description) ? $item->volumeInfo->description : false);
echo "<b>Title:</b> " . $booktitle;
echo "<b>Description:</b> " . $description;
}

<?php
$item = file_get_contents('https://www.googleapis.com/books/v1/volumes?q=Bowling%20Alone&maxResults=1');
$item = json_decode($item);
$item = reset($item->items);
$booktitle = (isset($item->volumesInfo->title) ? $item->volumeInfo->title : false);
$description = (isset($item->volumeInfo->description) ? $item->volumeInfo->description : false);
echo "<b>Title:</b> " . $booktitle;
echo "<b>Description:</b> " . $description;
?>
