How to check if many queries results are successful

Question

Is there a way to check if all queries (say 8) of one page are successful ?

Answer 1

I guess you are looking for this.

$mysqli= new mysqli(db-host,db-user,db-pass,db-name);
$query="select * from abc"; 
$result=$mysqli->query($query) or die($mysqli->error); 

similiar for all queries

$query1="...";
$$result2=...;
if($result && $result2) 
{ echo "successful"; }
