mysql_fetch_array
Fetch a result row as an associative array, a numeric array, or both
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

PDOStatement::fetch

array mysql_fetch_array(resource result,
int result_type= =MYSQL_BOTH);
Returns an array that corresponds to the fetched row and moves the internal data pointer ahead.
result
The result resource that is being
evaluated. This result comes from a call to
mysql_query
.
result_type
The type of array that is to be fetched. It's a
constant and can take the following values:
MYSQL_ASSOC
,
MYSQL_NUM
, and
MYSQL_BOTH
.
Returns an array of strings that corresponds to the fetched row,
or false
if there are no more rows. The
type of returned array depends on how
result_type
is defined. By using
MYSQL_BOTH
(default), you'll get an
array with both associative and number indices. Using
MYSQL_ASSOC
, you only get associative
indices (as
mysql_fetch_assoc
works), using MYSQL_NUM
, you only get
number indices (as
mysql_fetch_row
works).
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 must use the numeric index of the column or make an alias for the column. For aliased columns, you cannot access the contents with the original column name.
Example 6.17 Query with aliased duplicate field names
SELECT table1.field AS foo, table2.field AS bar FROM table1, table2
Example 6.18 mysql_fetch_array
with MYSQL_NUM
<?php mysql_connect("localhost", "mysql_user", "mysql_password") or die("Could not connect: " . mysql_error()); mysql_select_db("mydb"); $result = mysql_query("SELECT id, name FROM mytable"); while ($row = mysql_fetch_array($result, MYSQL_NUM)) { printf("ID: %s Name: %s", $row[0], $row[1]); } mysql_free_result($result); ?>
Example 6.19 mysql_fetch_array
with MYSQL_ASSOC
<?php mysql_connect("localhost", "mysql_user", "mysql_password") or die("Could not connect: " . mysql_error()); mysql_select_db("mydb"); $result = mysql_query("SELECT id, name FROM mytable"); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { printf("ID: %s Name: %s", $row["id"], $row["name"]); } mysql_free_result($result); ?>
Example 6.20 mysql_fetch_array
with MYSQL_BOTH
<?php mysql_connect("localhost", "mysql_user", "mysql_password") or die("Could not connect: " . mysql_error()); mysql_select_db("mydb"); $result = mysql_query("SELECT id, name FROM mytable"); while ($row = mysql_fetch_array($result, MYSQL_BOTH)) { printf ("ID: %s Name: %s", $row[0], $row["name"]); } mysql_free_result($result); ?>
An important thing to note is that using
mysql_fetch_array
is not significantly slower than using
mysql_fetch_row
,
while it provides a significant added value.
Field names returned by this function are case-sensitive.
This function sets NULL fields to
the PHP null
value.
