Hello im trying to sort values (NUMERIC) from for loop, my code:
$result_itemid_count = count($result_itemid);
for($x = 0; $x < $result_itemid_count; $x++) {
echo $result_itemid[$x][0];
echo "<br />";
}
output:

172505254931 172295676941 172295676941 172195402570 172195402570

i have no idea how to sort it, i tried sort, usort, ksort
any ideas?
first loop:
if ($resp->ack == "Success") {
$results = '';
$result_itemid = array();
// If the response was loaded, parse it and build links
foreach($resp->searchResult->item as $item) {
$pic = $item->galleryURL;
$link = $item->viewItemURL;
$title = $item->title;
$location = $item->location;
$itemid = $item->itemId;
$multiv = $item->isMultiVariationListing;
if($multiv == "true")
{
$result_itemid[] = [$itemid, $title];
} else {
// For each SearchResultItem node, build a link and append it to $results
$results .= "<tr><td align = 'center'><img src=\"$pic\"></td><td>$title - $location</td></tr>";
}
}
}
// If the response does not indicate 'Success,' print an error
else {
$results = "<h3>Oops! The request was not successful. Make sure you are using a valid ";
$results .= "AppID for the Production environment.</h3>";
}
second loop:
$result_itemid_count = count($result_itemid);
for($x = 0; $x < $result_itemid_count; $x++) {
echo $result_itemid[$x][0];
echo "<br />";
}

I hope you expected like below
$result_itemid[0][0]=121223;
$result_itemid[1][0]=121883;
$result_itemid[2][0]=121203;
$result_itemid[3][0]=121213;
$result_itemid[4][0]=121235;
$new_array=[];
$result_itemid_count = count($result_itemid);
for($x = 0; $x < $result_itemid_count; $x++) {
echo $result_itemid[$x][0];
echo "<br />";
array_push($new_array, $result_itemid[$x][0]);
}
echo "<hr/>";
sort($new_array);
$result_count = count($new_array);
for($x = 0; $x < $result_count; $x++) {
echo $new_array[$x];
echo "<br>";
}
