Hi,
I cannot figure this out... Need some assistance.
I have an array:
$jack[#] = array(
loan_info = 101,
first_name = jack,
last_name = mother
);
# = 0 thru 12
I want to sort the array by loan_info. Could someone please explain this
to me? I kind of understand array sorting, but I am still lost...

If you want to maintain key order, use uasort(); if, however, you want
the array to be reindexed sequentially when you sort it, use usort():

http://www.php.net/manual/en/function.usort.php
A short example (with the usual caveats about 'make sure you add error
checking):
?php
error_reporting(E_ALL);
$data =
array(array('loan_info' = 104,
'first_name' = 'jack',
'last_name' = 'mother'),
array('loan_info' = 102,
'first_name' = 'jill',
'last_name' = 'brother'),
array('loan_info' = 108,
'first_name' = 'jim',
'last_name' = 'the'),
array('loan_info' = 107,
'first_name' = 'bob',
'last_name' = 'whole'),
array('loan_info' = 105,
'first_name' = 'alice',
'last_name' = 'fam'),
array('loan_info' = 103,
'first_name' = 'ellen',
'last_name' = 'damily'));
function cmp($a, $b) {
return strcmp($a['loan_info'], $b['loan_info']);
}
uasort($data, 'cmp');
print_r($data);
?
Hope this helps,
Torben
