            [Reference Number] => PR_XHA_211
            [Pay Cheque Number] => N/A
            [Paid] => 0
        )

)

I need to arrange array in my required sequence of indexes which is like

[0] => Array
        (
            [Reference Number] => PR_XHA_210
            [Vendor Name] => Dept. of Economic Development.
            [BENEFICIARY NAME] => Self
            [LPO DATE] => 2011-04-13 10:08:37
            [LPO NUMBER] => PO1
            [LPO AMT] => 1000
            [Paid] => 0
            [AMOUNT] => 200
            [doc_id] => 2
            [doc_id] => 2
            [Pay Cheque Number] => N/A

        )

How It can be done? Pls Help...

Answer 1

Try this (untested):

$keys = array(
    'Reference Number',
    'Vendor Name',
    ...
);

$reordered = array();
foreach ($array as $item) {
    $new_item = array();
    foreach ($keys as $key) {
        $new_item[$key] = $item[$key];
    }
    $reordered[] = $new_item;
}

This will create a new array $reordered which holds all your rows, with the keys reordered according to the order defined in $keys.

Alternatively you could reorder your array in-place using uksort and a callback function (again, untested).

function sort_keys($a, $b) {
    static $keys = array(
        'Reference Number',
        'Vendor Name',
        ...
    );

    return array_search($a, $keys) - array_search($b, $keys);
}

foreach ($array as &$item) {
    uksort($item, 'sort_keys');
}

A third option is to leave your array alone but to edit your view code:

$keys = array(
    'Reference Number',
    'Vendor Name',
    ...
);

foreach ($array as $item) {
    foreach ($keys as $key) {
        printf('<tr><th>%s</th><td>%s</td></tr>',
            htmlspecialchars($key),
            htmlspecialchars($item[$key]));
    }
}
