For Each loop with 2 parent 'columns' - php

Question

I am trying to expand on some working code, and not sure how to do it.
Basicly the information can be under either information or some othertitle.
but i dont care for this split, i just want to do a foreach for all of them together.
Basicly i currently run a for each loop like this:
foreach ($info_array['information'] as $item) {... do something }
Would it be possible to somehow say, For each info_array 'information' & 'othertitle' as $item?
array is structured like:
information
random number
price
amount
total
random number
price
amount
total
othertitle
random number
price
amount
total
random number
price
amount
total
i tried this, but that didnt work:
foreach ($item_array['information'] as $item and $item_array['othertitle'] as $item)

The first idea that comes in mind is just use two loops - first one iterates over $item_array['information'], second one - over $item_array['othertitle']. Something like this:
foreach ($item_array['information'] as $item) {
echo $item['key1'] . ' -> ' . $item['key2'];
}
foreach ($item_array['othertitle'] as $item) {
echo $item['key1'] . ' -> ' . $item['key2'];
}
But, if you do the same output for each element of each array, you can do this:
$keys = ['information', 'othertitle'];
foreach ($keys as $key) {
echo 'Key is ' . $key . '<br />';
foreach ($item_array[$key] as $item) {
echo $item['key1'] . ' -> ' . $item['key2'];
}
}
And even it the output for arrays is different - you can solve it in this way:
$keys = ['information', 'othertitle'];
foreach ($keys as $key) {
echo 'Key is ' . $key . '<br />';
foreach ($item_array[$key] as $item) {
if ('information' === $key) {
echo 'Info: ' . $item['key1'] . ' -> ' . $item['key2'];
} else {
echo 'Ttile: ' . $item['key1'] . ' and ' . $item['key2'];
}
}
}
And if you have to iterate over all subarrays of $item_array, the solution is the same as in #AbraCadaver answer:
foreach ($item_array as $key => $items) {
echo 'Key is ' . $key . '<br />';
foreach ($items as $item) {
if ('information' === $key) {
echo 'Info: ' . $item['key1'] . ' -> ' . $item['key2'];
} else {
echo 'Ttile: ' . $item['key1'] . ' and ' . $item['key2'];
}
}
}

Since you know the indexes you could array_merge or use +:
foreach ($item_array['information'] + $item_array['othertitle'] as $item) {
// do something
}
Otherwise you need two loops:
foreach ($item_array as $array) {
foreach($array as $item) {
// do something
}
}
