PHP how to handle when there is no foreach loop? -

i have foreach loop runs without flaw.

foreach ($row $row) {    echo $row['id']; } 

there times there no rows returned. want echo out 'there no rows'; when there no rows. problem if try follows:

foreach ($row $row) {     if (!isset($row['id'])) {         echo 'there no rows';     } else {         echo $row['id'];     } } 

it never returns echo "there no rows". assume because when there no rows, foreach loop doesn't run. question becomes, how echo "there no rows" if , if there no rows while not interfering foreach when there rows.

i have tried code such as:

$row1 = $stmt->fetch(); $row = $stmt->fetchall();     if (isset($row1['id'])) {         foreach ($row $row) { 

still no luck

so desired outcome follows:

when loop runs: 1 2 3 4  when loop doesn't run: there no rows 

you should check before loop so

if(count($row)>0){ //foreach ... }else{ echo 'no data'; }
