mysqli_result::fetch_array -- mysqli_fetch_array — Fetch a result row as an associative, a numeric array, or both
객체 기반 형식
절차식 형식
Returns an array that corresponds to the fetched row or NULL
if there
are no more rows for the resultset represented by the
result
parameter.
mysqli_fetch_array() is an extended version of the mysqli_fetch_row() function. In addition to storing the data in the numeric indices of the result array, the mysqli_fetch_array() function can also store the data in associative indices, using the field names of the result set as keys.
Note: 이 함수가 반환하는 필드 이름은 대소문자를 구별합니다.
Note: 이 함수는 NULL 필드를 PHP
NULL
값으로 설정합니다.
If two or more columns of the result have the same field names, the last column will take precedence and overwrite the earlier data. In order to access multiple columns with the same name, the numerically indexed version of the row must be used.
result
순차 형식 전용: mysqli_query()나 mysqli_store_result()나 mysqli_use_result()가 반환한 결과셋 식별자.
resulttype
This optional parameter is a constant indicating what type of array
should be produced from the current row data. The possible values for
this parameter are the constants MYSQLI_ASSOC
,
MYSQLI_NUM
, or MYSQLI_BOTH
.
By using the MYSQLI_ASSOC
constant this function
will behave identically to the mysqli_fetch_assoc(),
while MYSQLI_NUM
will behave identically to the
mysqli_fetch_row() function. The final option
MYSQLI_BOTH
will create a single array with the
attributes of both.
Returns an array of strings that corresponds to the fetched row or NULL
if there
are no more rows in resultset.
Example #1 객체 기반 형식
<?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 LIMIT 3";
$result = $mysqli->query($query);
/* numeric array */
$row = $result->fetch_array(MYSQLI_NUM);
printf ("%s (%s)\n", $row[0], $row[1]);
/* associative array */
$row = $result->fetch_array(MYSQLI_ASSOC);
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
/* associative and numeric array */
$row = $result->fetch_array(MYSQLI_BOTH);
printf ("%s (%s)\n", $row[0], $row["CountryCode"]);
/* free result set */
$result->free();
/* close connection */
$mysqli->close();
?>
Example #2 절차식 형식
<?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 LIMIT 3";
$result = mysqli_query($link, $query);
/* numeric array */
$row = mysqli_fetch_array($result, MYSQLI_NUM);
printf ("%s (%s)\n", $row[0], $row[1]);
/* associative array */
$row = mysqli_fetch_array($result, MYSQLI_ASSOC);
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
/* associative and numeric array */
$row = mysqli_fetch_array($result, MYSQLI_BOTH);
printf ("%s (%s)\n", $row[0], $row["CountryCode"]);
/* free result set */
mysqli_free_result($result);
/* close connection */
mysqli_close($link);
?>
