MySQLI Prepared Statement: num_rows & fetch_assoc

Question

Below is some poorly written and heavily misunderstood PHP code with no error checking. To be honest, I\'m struggling a little getting my head around the maze of PHP->MySQLi

Answer 1

True, the Databasefunctions are a bit weird. You'll get there.

The code looks a bit iffy, but heres how it works:

A connection is build, a statement prepared, a parameter bound and it's executed, all well.

$result = $stmt->execute(); //execute() tries to fetch a result set. Returns true on succes, false on failure.
$stmt->store_result(); //store_result() "binds" the last given answer to the statement-object for... reasons. Now we can use it!

if ($stmt->num_rows >= "1") { //Uses the stored result and counts the rows.

  while($data = $result->fetch_assoc()){ 
        //And here, the answer-object is turned into an array-(object)
        // which can be worked with nicely.
        //It loops trough all entries in the array.
  }

}else{

   echo "0 records found";
}
