mysqli_result::fetch_array -- mysqli_fetch_array — Fetch a result row as an associative, a numeric array, or both

### Descrierea

Stil obiect-orientat

mysqli_result::fetch_array ([ int `$resulttype` = MYSQLI_BOTH ] ) : mixed

Stil procedural

mysqli_fetch_array ( mysqli_result `$result` [, int `$resulttype` = MYSQLI_BOTH ] ) : mixed

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.

> Notă: Numele câmpurilor întoarse de această funcție sunt sensibile la literele majuscule/minuscule.

> Notă: Această funcție stabilește câmpurile NULL la valoarea PHP `NULL`.

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.

### Parametri

`result`

  Numai stilul procedural: Un identificator al setului de rezultate întors de mysqli_query(), mysqli_store_result() sau mysqli_use_result ().

`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.

### Valorile întoarse

Returns an array of strings that corresponds to the fetched row or `NULL` if there are no more rows in resultset.

`<?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();
?>`

/* numeric array */
$row = mysqli_fetch_array($result, MYSQLI_NUM);

/* associative array */
$row = mysqli_fetch_array($result, MYSQLI_ASSOC);

/* 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 */
