    Create a boolean variable with false

    Iterate over the array and make this variable true in case the user found.

    In the last check the final value of the variable and if it is false then show the message No customer found.

    Here is a dynamic functional approach:

    $data = json_decode($customers, true);

function findCustomerInArr($array,$customerName){
    $customerFound = false;
    foreach($array as $a){
        if(strtolower($a['name']) == strtolower($customerName)){
            $customerFound = true;
            echo $customerName."'s phone is ".$a['phone'].PHP_EOL;
            echo $customerName."'s mobile is ".$a['mobile'].PHP_EOL;
            break;
        }
    }
    if(false == $customerFound){
        echo "No customer found with this name".PHP_EOL;
    }
}

findCustomerInArr($data,'sara');
findCustomerInArr($data,'aliveToDie');

    Note: You can remove strtolower() in case you want case-sensitive match.

    You may Code the loop and condition like this, It may solve the problem.

    $customers = '[
 {
  "id": 1,
  "name": "sara",
  "phone": 1100,
  "mobile": 1111
 },
 {
  "id": 2,
  "name": "ben",
  "phone": 2200,
  "mobile": 2222
 }
]';
$data = json_decode($customers, true);

$phone = Null;
$mobile = Null;
$name="sara";

foreach ($data as $a) {
   if ($a['name'] == $name) {
      $phone = $a['phone'];
      $mobile = $a['mobile'];
      break;
   }
}

if ($phone != Null && $mobile != Null) {
   echo "$name's phone is $phone n";
   echo "$name's mobile is $mobile";
}else{
   echo "No customer found with this name";
}
