Issue with stored procedure in PHP - php

Question

I have the following stored procedure that executes correctly when I run my program:
$insertIntoEmployeesProcedure = "
CREATE PROCEDURE EmployeeInsert(name VARCHAR(50),password VARCHAR(50), email VARCHAR(50))
BEGIN
INSERT INTO employees(name,password,email) values(name,password,email);
END";
$returnInsertIntoEmpProc = $conn->query($insertIntoEmployeesProcedure);
if(! $returnInsertIntoEmpProc )
{
die('Could not create insert procedure: ' . $conn->error);
}
else
{
echo "Insert Procedure created successfully<br/>";
}
I then call this procedure in another class when needed:
$insertEmp = mysqli_query($conn, "Call EmployeeInsert('$username','$password', '$email')");
$executeInsertEmp = $conn->query($insertEmp);
if(!$executeInsertEmp )
{
die('Employees not added: ' . $conn->error);
}
else
{
echo "Employees added<br/>";
}
The problem is, when I execute this code, I get the following error
Employees not added: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1' at line 1
The main issue I have with this is that even though it returns this error, the record is still added into the database and everything seems to be working fine. I guess I'm more curious as to why I'm getting this error as clearly I'm overlooking something.

Answer 1

Ah I see what I've done, I seem to have added an additional query which was unnecessary, the line:
$executeInsertEmp = $conn->query($insertEmp);
can be ommited, the check in the if statement is then done on the variable which holds the stored procedure. The following code works:
$insertEmp = mysqli_query($conn, "Call EmployeeInsert('$username','$password', '$email')");
if(!$insertEmp )
{
die('Employees not added: ' . $conn->error);
}
else
{
echo "Employees added<br/>";
}
