Examples

Example #1 Object oriented style

<?php
$mysqli 
= new mysqli("localhost""my_user""my_password""world");

/* check connection */
if (mysqli_connect_errno()) {
    
printf("Connect failed: %s\n"mysqli_connect_error());
    exit();
}

$query "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

if (
$result $mysqli->query($query)) {

    
/* fetch object array */
    
while ($row $result->fetch_row()) {
        
printf ("%s (%s)\n"$row[0], $row[1]);
    }

    
/* free result set */
    
$result->close();
}

/* close connection */
$mysqli->close();
?>

Example #2 Procedural style

<?php
$link 
mysqli_connect("localhost""my_user""my_password""world");

/* check connection */
if (mysqli_connect_errno()) {
    
printf("Connect failed: %s\n"mysqli_connect_error());
    exit();
}

$query "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

if (
$result mysqli_query($link$query)) {

    
/* fetch associative array */
    
while ($row mysqli_fetch_row($result)) {
        
printf ("%s (%s)\n"$row[0], $row[1]);
    }

    
/* free result set */
    
mysqli_free_result($result);
}

/* close connection */
mysqli_close($link);
?>

The above examples will output:

Pueblo (USA)

It's worth noting that the MySQLi functions (and, I presume, the MySQL functions) fetch a string regardless of the MySQL data type. E.g. if you fetch a row with an integer column, the corresponding value for that column and row will still be stored as a string in the array returned by mysql_fetch_row.

from "README.PHP4-TO-PHP5-THIN-CHANGES"

4. Be careful when porting from ext/mysql to ext/mysqli. The following
   functions return NULL when no more data is available in the result set
   (ext/mysql's functions return FALSE).

    - mysqli_fetch_row()
    - mysqli_fetch_array()
    - mysqli_fetch_assoc()

Note that mysqli_fetch() is deprecated but still is in PHP function list. mysqli_fetch_row() is nowadays mysql procedural style used, but is not listed in PHP functions.

Remember that fetch() and fetch_row() are two different things, and differ in the way to use them.

- fetch() is used on a statement (like an executed prepared statement) and needs to be used in association with bind_result().

- fetch_row() is used on a result (like the result of query()).

As a consequence, if you want to use to use fetch_row() with an executed prepared statement, first you'll have to get the result out of this statement with mysqli_store_result() or mysqli_use_result().
