PHP foreach loops and data retrieval - php

Question

Using PHP and MySQL I have generated two arrays. I would like to loop through these arrays, retrieve data from both and display together in one sentence.
foreach ($items as $item) {
if(isset($item->item_title)) {
$itemTitle = $item->item_title;
}
// var_dump($itemTitle);
// string(7) "Halfway" string(5) "Story" string(6) "Listen"
}
foreach ($aData["Items"]["Item"] as $a) {
if (isset($a['description'])) {
$aDescription = $a['description'];
}
// var_dump($aDescription );
// string(4) "Good" string(6) "Strong" string(2) "OK"
}
?>
Desired result;
The title is Halfway and the description is Good.
The title is Story and the description is Strong.
The title is Listen and the description is OK.
// etc
// etc
Is it possible to nest the foreach loops, or is there a better more efficient way?

Answer 1

Please try this way. Hope this help!!
foreach ($items as $index => $item) {
if(isset($item->item_title)) {
$itemTitle = $item->item_title;
echo 'The title is '.$itemTitle;
}
if(isset($aData["Items"]["Item"][$index]['description']) {
$itemDescription = $aData["Items"]["Item"][$index]['description'];
echo ' and the description is '.$itemDescription;
}
echo '<br>';
// The title is Halfway and the description is Good.
}

You can merge those two foreach loops using a simple for loop, like this:
$count = count($items) >= count($aData["Items"]["Item"]) ? count($aData["Items"]["Item"]) : count($items);
for($i = 0; $i < $count; ++$i){
if(isset($item[$i]->item_title)) {
$itemTitle = $item[$i]->item_title;
}
if (isset($aData["Items"]["Item"][$i]['description'])) {
$aDescription = $aData["Items"]["Item"][$i]['description'];
}
// your code
}
Sidenote: The above code assumes that two arrays $items and $aData["Items"]["Item"] have unequal number of elements, though this will work for equal number of elements as well. If you're sure that these two arrays will always have equal number of elements, then refactor the $count = ... ; statement in the following way,
$count = count($items);
or
$count = count($aData["Items"]["Item"]);
and use this $count variable in for loop.

Try this hope this will help you out.
Note: Here i am assuming both array's have same indexes.
$items
$aData["Items"]["Item"].
If not you can do array_values($items) and array_values($aData["Items"]["Item"])
foreach ($items as $key => $item)
{
if (isset($item->item_title) && isset($aData["Items"]["Item"][$key]['description']))
{
$itemTitle = $item->item_title;
echo sprinf("The title is %s and the description is %s",$itemTitle,$aData["Items"]["Item"][$key]['description']);
echo PHP_EOL;
}
}
