mysqli_result::fetch_array, mysqli_fetch_array
mysqli_result::fetch_arraymysqli_fetch_arrayFetch a result row as an associative, a numeric array, or both
Description
Object oriented stylemixed mysqli_result::fetch_array(int resulttype= =MYSQLI_BOTH);
Procedural stylemixed mysqli_fetch_array(mysqli_result result,
int resulttype= =MYSQLI_BOTH);
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
Field names returned by this function are case-sensitive.Note
This function sets NULL fields to the PHP NULL value.
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.
Parameters
result-
Procedural style only: A result set identifier returned by
mysqli_query,mysqli_store_resultormysqli_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, orMYSQLI_BOTH.By using the
MYSQLI_ASSOCconstant this function will behave identically to themysqli_fetch_assoc, whileMYSQLI_NUMwill behave identically to themysqli_fetch_rowfunction. The final optionMYSQLI_BOTHwill create a single array with the attributes of both.
Return Values
Returns an array of strings that corresponds to the fetched row or NULL if there are no more rows in resultset.
Examples
Example 20.179. 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 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->close();
/* close connection */
$mysqli->close();
?>
Example 20.180. 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 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);
?>
The above examples will output:
Kabul (AFG) Qandahar (AFG) Herat (AFG)
