mysqli_fetch_row

(PHP 5)

mysqli_fetch_row

(no version information, might be only in CVS)

result->fetch_row -- Get a result row as an enumerated array

Description

Procedural style:

mixed mysqli_fetch_row ( mysqli_result result )

Object oriented style (method):

class mysqli_result {

mixed fetch_row ( void )

}

Returns an array that corresponds to the fetched row, or NULL if there are no more rows.

mysqli_fetch_row() fetches one row of data from the result set represented by result and returns it as an enumerated array, where each column is stored in an array offset starting from 0 (zero). Each subsequent call to the mysqli_fetch_row() function will return the next row within the result set, or NULL if there are no more rows.

    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]);

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().

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.

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()
