Waarschuwing: > mysqli_fetch_array``PDOStatement::fetch

array **mysql_fetch_array** resource $result int $result_type

Returns an array that corresponds to the fetched row and moves the internal data pointer ahead.

result_type The type of array that is to be fetched. It's a constant and can take the following values: , , and . MYSQL_ASSOC``MYSQL_NUM``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 is defined. By using (default), you'll get an array with both associative and number indices. Using , you only get associative indices (as works), using , you only get number indices (as works). result_type``MYSQL_BOTH``MYSQL_ASSOC``mysql_fetch_assoc``MYSQL_NUM``mysql_fetch_row

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.

Voorbeeld: Query with aliased duplicate field names

SELECT table1.field AS foo, table2.field AS bar FROM table1, table2

**Voorbeeld: with **

<?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);
?>
