mysqli_result::fetch_assoc, mysqli_fetch_assoc
mysqli_result::fetch_assocmysqli_fetch_assocFetch a result row as an associative array
Description
Object oriented stylearray mysqli_result::fetch_assoc();
Procedural stylearray 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
result-
Procedural style only: A result set identifier returned by
mysqli_query,mysqli_store_resultormysqli_use_result.
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 or add alias names.
Examples
Example 20.181. 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 associative array */
while ($row = $result->fetch_assoc()) {
printf ('%s (%s)\n', $row['Name'], $row['CountryCode']);
}
/* free result set */
$result->free();
}
/* close connection */
$mysqli->close();
?>
Example 20.182. 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_assoc($result)) {
printf ('%s (%s)\n', $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 20.183. 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'\n', $row['user'], $row['host']);
}
echo '\n==================\n';
// Not using iterators
$result = $c->query('SELECT user,host FROM mysql.user');
while ($row = $result->fetch_assoc()) {
printf(''%s'@'%s'\n', $row['user'], $row['host']);
}
?>
The above example will output something similar to:
'root'@'192.168.1.1' 'root'@'127.0.0.1' 'dude'@'localhost' 'lebowski'@'localhost' ================== 'root'@'192.168.1.1' 'root'@'127.0.0.1' 'dude'@'localhost' 'lebowski'@'localhost'
