Re: [PHP] How to sort by 3rd row in an 2d-Array
usort() /uksort()/uasort()
look here :
http://www.php.net/manual/en/function.uasort.php
There is an example in the user notes.

Subject: [PHP] How to sort by 3rd row in an 2d-Array
Hi,
I'm trying to sort an array like following
myArray[1][firstname] = Joe;
myArray[1][lastname] = Smith;
myArray[1][company] = Bullock;
myArray[1][email] = [EMAIL PROTECTED];
myArray[2][firstname] = Jim;
myArray[2][lastname] = Cords;
myArray[2][company] = Jamen;
myArray[2][email] = [EMAIL PROTECTED];
etc...
by the company name. How can I do it?
I found the solution on php.net
(http://www.php.net/manual/en/function.array-multisort.php) but it sorts
only the first row:
foreach ($myArray as $val) {
$sortarray[] = $val['nafn'];
echo $val['stadur'];
}
array_multisort($myArray, $sortarray);
Thanks in advance!

Re: [PHP] How to sort by 3rd row in an 2d-Array
This is a terribly inneficient way of handling your situation but I believe
it would work.
// First we're going to make a list of all company values
for($i=0; $icount($myarray); $i++)
{
$company_values[] = $myarray[$i][company];
}
// Then we're going to order the array using a standard function.
natsort($company_values);
// Then we're going to go through $myarray looking for each matching
// value and build a new array based on the order of the sorted list.
for($i=0; $icount($company_values); $i++)
{
for ($j=0; $j=count($myarray); $j++)
{
if ($company_values[$i] == $myarray[$j][company])
{
$mynewarray[] = $myarray[$j];
}
}
}
// bada bing bada boom you gots your company sorted list... I think
$myarray = $mynewarray;
I wrote this off the top of my head in like three minutes so any and all
corrections would be most welcome. ;)

Re: [PHP] How to sort by 3rd row in an 2d-Array
Or try the usort() function?
?php
...
myArray[1][firstname] = Joe;
myArray[1][lastname] = Smith;
myArray[1][company] = Bullock;
myArray[1][email] = [EMAIL PROTECTED];
myArray[2][firstname] = Jim;
myArray[2][lastname] = Cords;
myArray[2][company] = Jamen;
myArray[2][email] = [EMAIL PROTECTED];
...
function companyCmp ($a, $b) {
return strcmp($a[company],$b[company]);
}
usort ($myArray, companyCmp);
...
?
