mysqli_result::fetch_array -- mysqli_fetch_array — Fetch the next row of a result set as an associative, a numeric array, or both
Estilo orientado a objetos
$mode
= MYSQLI_BOTH
): array|null|falseEstilo procedural
Fetches one row of data from the result set and returns it as an array.
Each subsequent call to this function will return the next row within the
result set, or null
if there are no more rows.
In addition to storing the data in the numeric indices of the result array, this function can also store the data in associative indices by using the field names of the result set as keys.
If two or more columns of the result have the same name, the last column will take precedence and overwrite any previous data. To access multiple columns with the same name, the numerically indexed version of the row must be used.
Nota: Os nomes de campos retornados por esta função diferenciam maiúsculas e minúsculas.
Nota: Esta função define campos NULL como o valor
null
do PHP.
result
Somente no estilo procedural: Um objeto mysqli_result retornado por mysqli_query(), mysqli_store_result(), mysqli_use_result() ou mysqli_stmt_get_result().
mode
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 representing the fetched row, null
if there
are no more rows in the result set, ou false
em caso de falha.
Exemplo #1 mysqli_result::fetch_array() example
Estilo orientado a objetos
<?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 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"]);
Estilo procedural
<?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 LIMIT 3";
$result = mysqli_query($mysqli, $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"]);
