Code:
#!/bin/bash

# We create an example array 'a' containing 16 values:
# array a = ( 0 1 2 3 4 ... 14 15 )
a=({0..15})

echo 'Linear array:'
echo ${a[*]}

# We now display this array 'a' in a 4x4 grid
echo 'Matrix array:'
for row in {1..4}; do
    for col in {1..4}; do
        echo -n ${a[((4*row+col-5))]}$'\t'

ingres_fetch_assoc - Fetch a row of result into an associative array

SYNOPSIS
array ingres_fetch_assoc (resource $result) DESCRIPTION
This function is stores the data fetched from a query executed using ingres_query(3) in an associative array, using the field names as keys. With regard to speed, the function is identical to ingres_fetch_object(3), and almost as quick as ingres_fetch_row(3) (the difference is insignificant). By default, arrays created by ingres_fetch_assoc(3) start from position 1 and not 0 as with other DBMS extensions. The starting position can be adjusted to 0 using the configuration parameter ingres.array_index_start. Note Related Configurations See also the ingres.array_index_start, ingres.fetch_buffer_size and ingres.utf8 directives in Runtime Configuration. PARAMETERS
o $result - The query result identifier RETURN VALUES
Returns an associative array that corresponds to the fetched row, or FALSE if there are no more rows EXAMPLES
Example #1 Fetch a row into an associative array <?php $link = ingres_connect($database, $user, $password); $result = ingres_query($link,"select * from table"); while ($row = ingres_fetch_assoc($result)) { echo $row["user_id"]; // using associative array echo $row["fullname"]; } ?> SEE ALSO
ingres_query(3), ingres_num_fields(3), ingres_field_name(3), ingres_fetch_array(3), ingres_fetch_object(3), ingres_fetch_row(3). PHP Documentation Group INGRES_FETCH_ASSOC(3)
