Read data from mysqli_fetch_array like a multidimensional array?

Question

When I use mysqli_fetch_array() I get an array, but how do I read the values? Is a While-Loop the only option, or can I pick any value from a row and column like a

Answer 1

It depends how you are returning your results from the database.

there are flags in your mysqli_fetch_array function which you can set to modify your returned result.

If you use $row = mysqli_fetch_array($result, MYSQLI_ASSOC); or in OOP $row = $result->fetch_array(MYSQLI_ASSOC);

then you can access your returned result as column name in your while loop like $row['name'] or $row['age']

Or if you use $row = mysqli_fetch_array($result, MYSQLI_NUM); or in OOP $row = $result->fetch_array(MYSQLI_NUM);

then you can access your returned result in while loop like $row[0] or $row[3]

Simple example would be

while($row = mysqli_fetch_array($result)) {
    echo $row['name'] . " " . $row['age'];
}
