mysqli_fetch_assoc
(PHP 5)
mysqli_fetch_assoc
(no version information, might be only in CVS)
mysqli->fetch_assoc -- Fetch a result row as an associative array
Description
Procedural style:
array
mysqli_fetch_assoc ( object result)
Object oriend style (method):
class
result {
array
fetch_assoc ( void )
}
Returns an associative array that corresponds to the fetched row or NULL if there are
no more rows.
The mysqli_fetch_assoc() function is used to return an associative array
representing the next row in the result set for the result represented by the
result parameter, where each key in the array represents the name
of one of the result set's columns.
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.
Return values
Returns an array that corresponds to the fetched row or NULL if there are no more rows in resultset.
Example
例子 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();
?>

例子 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);
?>
