$input = str_replace('var tumblr_api_read = ','',$input);
$input = str_replace(';','',$input);
// parameter 'true' is necessary for output as PHP array
$value = json_decode($input, true);
$content =  $value['posts'];

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
