mysqli_result::fetch_array
[This describes the syntax difference in calling $result->fetch_assoc().]
<?php
/* fetch associative array works inside a while loop */
while ($row = $result->fetch_assoc()) {
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
// works
/* fetch associative array doesn't work inside a foreach */
foreach($result->fetch_assoc() as $row) {
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
// fails
?>
mysqli_result::fetch_assoc
mysqli_fetch_assoc
(PHP 5)
mysqli_result::fetch_assoc -- mysqli_fetch_assoc — Fetch a result row as an associative array
Description
Object oriented style (method):
array mysqli_result::fetch_assoc
( void
)
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
- result
-
Procedural style only: A result set identifier returned by mysqli_query(), mysqli_store_result() or mysqli_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 #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 associative array */
while ($row = $result->fetch_assoc()) {
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
/* 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_assoc($result)) {
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
/* free result set */
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>
The above example will output:
Pueblo (USA) Arvada (USA) Cape Coral (USA) Green Bay (USA) Santa Clara (USA)
