I have a 4 column mysql table, the leftmost being the autoincrement column and I'd like to get the variable value for a column called extra
for the highest auto increment value. I believe the SQL query will be:
Select extra FROM motoron2 ORDER BY id DESC LIMIT 1"
$conn = new mysqli('localhost', 'myuser', 'mypass', 'mydb');
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT extra FROM motoron2 ORDER BY id DESC LIMIT 1";
$stmt = $conn->prepare($sql);
$stmt->execute();
$result = $stmt->get_result(); // get the mysqli result
$variablevalue = $result->fetch_assoc(); // fetch the data
echo "The variable is converted to a string and its value is $variablevalue.";
// set parameters and execute
When try to echo "The variable is converted to a string and its value is $variablevalue."
I see: The variable is converted to a string and its value is Array
I am expecting to see an integer here, what am I doing wrong?
CodePudding user response:
The fetch_assoc()
function returns an associative array so you would access the value by the name of the column:
$variablevalue['extra']
;
