I am trying to loop through a multidimensional array and keep banging my head against the wall trying to figure it out. I am essentially trying to print all values of ID.
This is what I have so far, but it keeps giving me an "array to string conversion" error.
foreach ($threadsarray as $key => $threads) {
foreach ($threads as $anotherkey => $i) {
foreach($i as $id => $threadid)
echo 'key:'.$key[0]. ' AnotherKey: '.$anotherkey["threads"].' AnotherAnotherKey: '.$i["id"].' value:'.$threadid.'<br>';
}
}
I'm trying to mimic what this would do, but using a "For Loop"
$threadsarray['threads']['0']['id'];
$threadsarray['threads']['1']['id'];
And here is the array.....
Array
(
[threads] => Array
(
[0] => Array
(
[archived] =>
[attachment] =>
[business_purpose] => booking_direct_thread
[id] => 178369845
[inquiry_reservation] =>
[last_message_at] => 2017-04-07T18:52:07Z
[listing] => Array
(
This is the way it can be done
foreach ($threadsarray['threads'] as $thread) {
print $thread['id'];
}
for version
$idx = count($threadsarray['threads']);
for($i=0;$i<$idx;$i++){
print $threadsarray['threads'][$i]['id'];
}
The error you are getting is because you are trying to echo out an Array.
I would do this:
foreach($threadsarray['threads'] as $key => $thread){
echo 'key:' . $key . ' - ';
foreach($thread as $key2 => $value2){
echo 'key2:' . $key2 . ' - ';
if(is_array($value2)){
foreach($value2 as $key3 => $value3){
echo 'key3:' . $key3 . ' - value3: ' . $value3;
}
}else{
echo 'value: ' . $value2;
}
}
}
you can always inspect the whole array structure doing print_r($threadsarray)
Better use a recursive function for any amount of 'levels':
function printAll($a) {
if (!is_array($a)) {
echo $a, ' ';
return;
}
foreach($a as $k => $value) {
printAll($k);
printAll($value);
}
}
You can call it like: printAll($threadsarray);
