Answer 1

Try this:
$json = '{"0":{"categories":[{"name":"Football Club","slug":"football-club"}],"tags":[{"name":"England","slug":"england"},{"name":"EPL","slug":"epl"},{"name":"Europe","slug":"europe"},{"name":"Champions","slug":"champions"}],"ID":"908","post_author":"78350","post_date":"2010-10-18 10:49:16","post_title":"Liverpool Football Club","post_content":"Content goes here...","post_name":"liverpoolfc","guid":"http://www.liverpoolfc.tv","post_type":"post","comment_count":"0","comment_status":"open","relevance_count":0},"1":{"categories":[{"name":"Football Club","slug":"football-club"}],"tags":[{"name":"England","slug":"england"},{"name":"EPL","slug":"epl"},{"name":"Europe","slug":"europe"},{"name":"Champions","slug":"champions"}],"ID":"907","post_author":"78350","post_date":"2010-10-18 10:49:16","post_title":"Everton Football Club","post_content":"Content goes here","post_name":"evertonfc","guid":"http://www.evertonfc.tv","post_type":"post","comment_count":"0","comment_status":"open","relevance_count":0}}';
$array = json_decode($json, true);
foreach ($array as $item) {
echo '<ul>' . PHP_EOL;
echo '<li>' . $item['post_title'] . '</li>' . PHP_EOL;
echo '<li>' . $item['post_content'] . '</li>' . PHP_EOL;
/* Display Categories */
echo '<li>Categories' . PHP_EOL;
echo '<ul>' . PHP_EOL;
if (!empty($item['categories'])) {
foreach ($item['categories'] as $category) {
echo '<li>' . $category['name'] . '</li>' . PHP_EOL;
}
} else {
echo '<li>No Categories Available</li>' . PHP_EOL;
}
echo '</ul>' . PHP_EOL;
echo '</li>' . PHP_EOL;
/* Display Tags */
echo '<li>Tags' . PHP_EOL;
echo '<ul>' . PHP_EOL;
if (!empty($item['tags'])) {
foreach ($item['tags'] as $tag) {
echo '<li>' . $tag['name'] . '</li>' . PHP_EOL;
}
} else {
echo '<li>No Tags Available</li>' . PHP_EOL;
}
echo '</ul>' . PHP_EOL;
echo '</li>' . PHP_EOL;
echo '</ul>' . PHP_EOL;
}
UPDATE Are you asking on how to do this in PHP or in Javascript/jQuery? You didn't quite explain what you were doing with it.
UPDATE Here it is using Javascript/jQuery: http://jsfiddle.net/wgjjR/
//<div id="container"></div>
//var json = {}; // this is your JSON object
var container = $('#container'), html = [];
for (var key in json) {
var item = json[key];
html.push('<ul>');
html.push('<li>' + item.post_title + '</li>');
html.push('<li>' + item.post_content + '</li>');
html.push('<li>Categories<ul>');
for (var cat in item.categories) {
cat = item.categories[cat];
html.push('<li>' + cat.name + '</li>');
}
html.push('</ul></li>');
html.push('<li>Tags<ul>');
for (var tag in item.tags) {
tag = item.tags[tag];
html.push('<li>' + tag.name + '</li>');
}
html.push('</ul></li>');
html.push('</ul>');
}

Answer 2

$json = json_decode($inputJson, true);
foreach($json as $key => $value)
{
// do somethig
}

Answer 3

Use json_decode
$json = json_decode($some_json, true);
$element1 = $json["item"]["element1"];
$element2 = $json["item"]["element2"];
Repeat to extract all the values you require.
