mysqli_result::data_seek - Adjusts the result pointer to an arbitrary row in the result

       Object oriented style

SYNOPSIS
bool mysqli_result::data_seek (int $offset) DESCRIPTION
Procedural style bool mysqli_data_seek (mysqli_result $result, int $offset) The mysqli_data_seek(3) function seeks to an arbitrary result pointer specified by the $offset in the result set. PARAMETERS
o $ result -Procedural style only: A result set identifier returned by mysqli_query(3), mysqli_store_result(3) or mysqli_use_result(3). o $offset - The field offset. Must be between zero and the total number of rows minus one (0..mysqli_num_rows(3) - 1). RETURN VALUES
Returns TRUE on success or FALSE on failure. NOTES
Note This function can only be used with buffered results attained from the use of the mysqli_store_result(3) or mysqli_query(3) func- tions. EXAMPLES
Example #1 Object oriented style <?php /* Open a connection */ $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s ", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER BY Name"; if ($result = $mysqli->query($query)) { /* seek to row no. 400 */ $result->data_seek(399); /* fetch row */ $row = $result->fetch_row(); printf ("City: %s Countrycode: %s ", $row[0], $row[1]); /* free result set*/ $result->close(); } /* close connection */ $mysqli->close(); ?> Example #2 Procedural style <?php /* Open a connection */ $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (!$link) { printf("Connect failed: %s ", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER BY Name"; if ($result = mysqli_query($link, $query)) { /* seek to row no. 400 */ mysqli_data_seek($result, 399); /* fetch row */ $row = mysqli_fetch_row($result); printf ("City: %s Countrycode: %s ", $row[0], $row[1]); /* free result set*/ mysqli_free_result($result); } /* close connection */ mysqli_close($link); ?> The above examples will output: City: Benin City Countrycode: NGA SEE ALSO

mysqli_result::fetch_assoc - Fetch a result row as an associative array

       Object oriented style

SYNOPSIS
array mysqli_result::fetch_assoc (void ) DESCRIPTION
Procedural style array mysqli_fetch_assoc (mysqli_result $result) Returns an associative array that corresponds to the fetched row or NULL if there are no more rows. Note Field names returned by this function are case-sensitive. Note This function sets NULL fields to the PHP NULL value. PARAMETERS
o $ result -Procedural style only: A result set identifier returned by mysqli_query(3), mysqli_store_result(3) or mysqli_use_result(3). RETURN VALUES
Returns an associative array of strings representing the fetched row in the result set, where each key in the array represents the name of one of the result set's columns or NULL if there are no more rows in resultset. If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you either need to access the result with numeric indices by using mysqli_fetch_row(3) or add alias names. 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 ", $mysqli->connect_error); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5"; if ($result = $mysqli->query($query)) { /* fetch associative array */ while ($row = $result->fetch_assoc()) { printf ("%s (%s) ", $row["Name"], $row["CountryCode"]); } /* free result set */ $result->free(); } /* 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 ", 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_assoc($result)) { printf ("%s (%s) ", $row["Name"], $row["CountryCode"]); } /* free result set */ mysqli_free_result($result); } /* close connection */ mysqli_close($link); ?> The above examples will output: Pueblo (USA) Arvada (USA) Cape Coral (USA) Green Bay (USA) Santa Clara (USA) Example #3 A mysqli_result example comparing iterator usage <?php $c = mysqli_connect('127.0.0.1','user', 'pass'); // Using iterators (support was added with PHP 5.4) foreach ( $c->query('SELECT user,host FROM mysql.user') as $row ) { printf("'%s'@'%s' ", $row['user'], $row['host']); } echo " ================== "; // Not using iterators $result = $c->query('SELECT user,host FROM mysql.user'); while ($row = $result->fetch_assoc()) { printf("'%s'@'%s' ", $row['user'], $row['host']); } ?> The above example will output something similar to: ================== SEE ALSO
