Accessing url for images in tumblr search API - php

Question

I am trying to access the urls of the first images that show up for tumblr searches using the tag search api. Below is the json for the test search I'm using.
{
"meta": {
"status": 200,
"msg": "OK"
},
"response": [
{
"blog_name": "m00tzman",
"id": 37918165271,
"post_url": "http://m00tzman.tumblr.com/post/37918165271/test-image-for-tumblr-a…",
"slug": "test-image-for-tumblr-api-thingy",
"type": "photo",
"date": "2012-12-14 18:13:25 GMT",
"timestamp": 1355508805,
"state": "published",
"format": "html",
"reblog_key": "IwlKk9r4",
"tags": [
"g6845e"
],
"highlighted": [ ],
"note_count": 29,
"caption": "<p>test image for tumblr api thingy</p>",
"photos": [
{
"caption": "",
"alt_sizes": [
{
"width": 500,
"height": 628,
"url": "http://25.media.tumblr.com/af60fbe390c487125501e50b37781317/tumblr_…"
},
{
"width": 400,
"height": 502,
"url": "http://25.media.tumblr.com/af60fbe390c487125501e50b37781317/tumblr_…"
},
{
"width": 250,
"height": 314,
"url": "http://25.media.tumblr.com/af60fbe390c487125501e50b37781317/tumblr_…"
},
{
"width": 100,
"height": 126,
"url": "http://24.media.tumblr.com/af60fbe390c487125501e50b37781317/tumblr_…"
},
{
"width": 75,
"height": 75,
"url": "http://24.media.tumblr.com/af60fbe390c487125501e50b37781317/tumblr_…"
}
],
"original_size": {
"width": 500,
"height": 628,
"url": "http://25.media.tumblr.com/af60fbe390c487125501e50b37781317/tumblr_…"
}
}
]
}
]
}
My problem is that I am not able to echo out the url for the "original size" image. Here is my code so far:
<?php
$search = file_get_contents('http://api.tumblr.com/v2/tagged?tag=g6845e&api_key=(api key)');
$tumblrdata = json_decode($search, true);
$photos = $tumblrdata['photos']['original_size'];
$url = $photos['url'];
echo $url;
?>
Any guesses on what is going wrong here?

Answer 1

Try
$photos = $tumblrdata['response']['photos'][0]['original_size'];
