Answer 1

for example , you can call multiple stored procedure like this below code

$db = mysqli_connect([...]);  


$r = mysqli_query($db, " CALL getSomething(2); ");  
while($row = mysqli_fetch_assoc($r)) {  
      print_r($row);  
}  

mysqli_free_result($r);  
mysqli_next_result($db);  

$r = mysqli_query($db, " CALL getSomethingElse(); ");  
while($row = mysqli_fetch_assoc($r)) {  
      print_r($row);  
}  

mysqli_free_result($r);
mysqli_next_result($db);  
mysqli_close($db);

it is important to use the functions mysqli_free_result() and mysqli_next_result() after the MySQL stored procedure is called, otherwise, the code will not work and you may see an error like "Commands out of sync; you can't run this command now".
