How can I extract values out of this array?

Question

Array ( [status] => success 
 [stories] => Array ( 
 [0] => Array ( [name] => John Doe 
 [age] => 23)
 [1] => Array ( [name] => John Doe_1
 [age] => 23)
 [2] => Array ( [name] => John Doe_2
 [age] => 23)
 )
) 

When I try

foreach($stories as $story){ }

It returns an error.

Update: I am trying to pull out the most recent stories from Tweetmeme. Since the json output was long, I shortened it. :)

The PHP Code:

$json=file_get_contents($url);
 $data=json_decode($json,true);
 print_r($data);
 foreach($stories as $story){
 $title = mysql_real_escape_string($story['title']);
 $url_temp = mysql_real_escape_string($story['url']);
 $tweets = intval($story['url_count']);
JSON Output:
Array ( [status] => success 
 [stories] => Array ( [0] => Array ( [title] => Steve Jobs has a Flash enabled iPad!

• Jagira: I made an error in the quesstion. It is "stories" not "abc". Corrected. :)
• Jagira: THE ERROR IS "Invalid argument supplied for foreach() in...."
• Álvaro González: You try to read from $stories but you never define it :-?
• Jagira: Gotcha. The correct statement should be foreach($data[stories] as $story){} Thanks for the help guys. Mark and Alvaro, you guys saved my ass. :)

Answer 1

You simply forgot to initialize the variable $data. Please include this line before the for-loop:

$stories = $data['stories'];

Keep in mind that json_decode itself does not create local variables!

Answer 2

You could also do it like this:

foreach($stories as $story) {
 if(is_array($story)) {
 foreach($story as $person) {
 print "{$person['name']}, {$person['age']}<br />";
 }
 }
}

That gives you a bit of flexibility if the key containing the sub-array changes or if your data is ever going to have multiple sub-arrays with data in them.

• Mark Biek: That sounds like whatever variable you're passing to the foreach loop isn't really an array. Posting more code might be helpful. Can you post the code that generates the array?
• Jagira: The code is bulky, so i shortened it. Anyway I will try to post the code.
• Jagira: I am pulling the list of Recent Stories from Tweetmeme.
• Mark Biek: I think the problem is that your foreach() loop uses the variable $stories but you seem to be decoding the JSON data into the variable $data.

Answer 3

Not sure what error does it return, but have you tried

foreach($stories['abc'] as $story){ 
}

instead?

Answer 4

Do you need to reference the variable you have the array in? Something like foreach($json.stories as $story) ...?

Answer 5

foreach ( $whatever_you_named_your_array['stories'] as $story ) {

}

Answer 6

for ($i = 0; $i < count($array1['abc']); $i++)
{
 $current = $array1['abc'][$i];
}

That should do it.

Answer 7

try

foreach ($data AS $story){
 if(is_array($story)) {
 foreach($story as $person) {
 print_r($person);
 }
 }
}
