mysqli_result::fetch_assoc
mysqli_fetch_assoc
Fetch a result row as an associative array
Description
Object oriented style
public array mysqli_result::fetch_assoc();
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.
Field names returned by this function are case-sensitive.
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
ormysqli_use_result
.
Return Values
Returns an associative array of values 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 result
set.
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 3.110 mysqli_result::fetch_assoc
example
Object oriented style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER BY ID DESC";
$result = $mysqli->query($query);
/* fetch associative array */
while ($row = $result->fetch_assoc()) {
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
Procedural style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = mysqli_connect("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER BY ID DESC";
$result = mysqli_query($mysqli, $query);
/* fetch associative array */
while ($row = mysqli_fetch_assoc($result)) {
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
The above examples will output something similar to:
Pueblo (USA) Arvada (USA) Cape Coral (USA) Green Bay (USA) Santa Clara (USA)
Example 3.111 Comparison of mysqli_result
iterator
and
mysqli_result::fetch_assoc
usage
mysqli_result
can be iterated using
foreach.
The result set will always be iterated from the first row,
regardless of the current position.
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$query = 'SELECT Name, CountryCode FROM City ORDER BY ID DESC';
// Using iterators
$result = $mysqli->query($query);
foreach ($result as $row) {
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
echo "\n==================\n";
// Not using iterators
$result = $mysqli->query($query);
while ($row = $result->fetch_assoc()) {
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
The above example will output something similar to:
Pueblo (USA) Arvada (USA) Cape Coral (USA) Green Bay (USA) Santa Clara (USA) ================== Pueblo (USA) Arvada (USA) Cape Coral (USA) Green Bay (USA) Santa Clara (USA)
