PHP foreach loop through array - php

Question

I have a fairly big array that I source from Facebook:
array(25) {
[0]=>
array(14) {
["id"]=>
string(31) "245226895508982_651884328176568"
["from"]=>
array(2) {
["name"]=>
string(16) "Madeleine Björs"
["id"]=>
string(15) "100002249777453"
}
["to"]=>
array(1) {
["data"]=>
array(1) {
[0]=>
array(2) {
["name"]=>
string(31) "Wohnung/WG in München gesucht!"
["id"]=>
string(15) "245226895508982"
}
}
}
Now what I want to do is go through the array and save ID, name and various other information from that array into a mysql database. However, to understand how to target specific information I tried to echo the data first.
$data = json_decode(file_get_contents('https://graph.facebook.com/'), true);
foreach($data as $item) {
echo $item['id'];
echo '<pre>'; var_dump($item);
}
This PHP code is based on various posts on Stackoverflow, however, the code returns nothing. May you please help me to target the arrays appropriately? You may check the enire array here: http://faculty-fight.de/milliondollaridea/facebook_session.php

Answer 1

foreach($array as $key=>$subArray)
{
foreach($subArray as $subKey=>subSubArray)
{
if(is_array($subSubArray))
{
foreach($subSubArray as $subSubKey=>$value)
{
if(is_array($value))
{
foreach($value as $valueKey=>$subValue)
{
/* your code /*
}
}
}
}
}
you can check for id values for example for 1st loop (if($subKey == "to")).
