过滤数组php有两个条件

I'm trying to get the bottom values of an array with two conditions as below :

1. Get all numeric values from the bottom until the next value is a string then stop the instruction, and leave all other values even if they are numeric
2. If the first values from the bottom are strings skip them and execute the first condition.

<?php $data=[1,2,3,'web',4,5,6,'web',7,8,9]; ?>

The output will be 7 8 9.

<?php $data= [1,2,3,'web',4,5,6,'web',7,8,9,'web','web']; ?>

<?php $data= [1,2,3,'web',4,5,6,'web',7,8,9,'web']; ?>

Both of conditions will have the same output: 7 8 9.

Logic: Reverse the array and check weather the given element is integer, if it is an integer, put it into a temporary array, otherwise, check if the process of saving integer data has already been started, if yes, break the loop otherwise, continue with the loop. Finally, reverse the array again to get the data in same format.

<?php
$data= [1,2,3,'web',4,5,6,'web',7,8,9,'web'];
$process = false;
foreach(array_reverse($data) as $d){
    if(is_int($d)){
        $process = true;
        $temp[] = $d;
    }
    else if($process) break;
}
$result = array_reverse($temp);
print_r($result);
?>
