mysql_fetch_array
Fetch a result row as an associative array, a numeric array, or both
(PHP 4, PHP 5, PECL mysql:1.0)
array mysql_fetch_array ( resource result [, int result_type] )
Parameters
- 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 the default value ofMYSQL_BOTH.
Return Values
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.
Examples
Example 1426. Query with aliased duplicate field names
SELECT table1.field AS foo, table2.field AS bar FROM table1, table2
Example 1427. 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 1428. 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 1429. 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);
?>
Notes
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
PHP NULL value.
