$request = 'http://walltumbler.tumblr.com/api/read/json';
$ci = curl_init($request);
curl_setopt($ci, CURLOPT_RETURNTRANSFER, TRUE);
$input = curl_exec($ci);
// Tumblr JSON doesn't come in standard form, some str replace needed
$input = str_replace('var tumblr_api_read = ','',$input);
$input = str_replace(';','',$input);
// parameter 'true' is necessary for output as PHP array
$value = json_decode($input, true);
$content = $value['posts'];
// the number of items you want to display
$item = 98988;
// Tumblr provides various photo size, this case will choose the 75x75 square one
$type = 'photo-url-1280';
?>

<?php

Try using the json_encode() function
<?php
$request = 'http://walltumbler.tumblr.com/api/read/json';
$ci = curl_init($request);
curl_setopt($ci, CURLOPT_RETURNTRANSFER, TRUE);
$input = curl_exec($ci);
$input = str_replace('var tumblr_api_read = ','',$input);
$input = str_replace(';','',$input);
$value = json_decode($input, true);
$content = $value['posts'];
$item = 98988;
$type = 'photo-url-1280';
$photos_array = array();
for ($i=0;$i<=$item;$i++) {
if ($content[$i]['type'] == 'photo') {
$photos_array[] = array(
'id' => $i,
'author' => 'Paul Jarvis',
// Continue with all your values...
);
}
}
$json_data = array(
'limit' => null,
'offset' => 0,
'count' => 2442,
'total' => 2442,
'data' => $photos_array
);
// Then use json_encode to get your json data...
echo json_encode( $json_data );
Hope it helps
