I want to concatenate all the octent and get the result as 131.208.0.0 and 141.128.0.0 to pass to view to display.

Array
(
    [0] => Array
        (
            [octet1] => 131
            [octet2] => 208
            [octet3] => 0
            [octet4] => 0
        )

    [1] => Array
        (
            [octet1] => 141
            [octet2] => 128
            [octet3] => 0
            [octet4] => 0
        )
)

With the below foreach I get all ailments how do i concatenate each octent for an array.

 foreach($arr as $external)
       {
            foreach ($external as $octent)
            {
                echo $octent."<br />";
            }
       }

The implode function is what you are searching for:

 $results = array();
 foreach($arr as $external){
       $results[] = implode('.', $external);
 }

 print_r($results);
