mysql_fetch_array
Fetch a result row as an associative array, a numeric array, or both.
Description
arraymysql_fetch_array
resourceresult
int
result_type
Returns an array that corresponds to the fetched row, or &false;
if there are no more rows.
mysql_fetch_array is an extended version of
mysql_fetch_row. In addition to storing the
data in the numeric indices of the result array, it also stores
the data in associative indices, using the field names as keys.
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 (by using
'field' in this example).
Query with duplicate field names
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.
The optional second argument result_type
in mysql_fetch_array is a constant and can
take the following values: MYSQL_ASSOC, MYSQL_NUM, and
MYSQL_BOTH. This feature was added in PHP 3.0.7. MYSQL_BOTH
is the default for this argument.
By using MYSQL_BOTH, 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).
