[SOLVED] having issues sorting numbers with sort()

[DamienRoche]

From the tutorials I've read this should be working.

 

Here's the array and the sort:

 

<?php

Array ( [0] => 1,249 [1] => 33,182 [2] => 33,182 [3] => 9,333 [4] => 3,981,847 [5] => 9,149 [6] => 3,294 [7] => 17,928 [8] => 1,413 [9] => 2,994 ) 

$fig is as above;

sort($fig);

print_r($fig);

?>

 

OUTPUT:

<?php

Array ( [0] => 1,249 [1] => 1,413 [2] => 17,928 [3] => 2,994 [4] => 3,294 [5] => 3,981,847 [6] => 33,182 [7] => 33,182 [8] => 9,149 [9] => 9,333 ) 
?>

The sort is having some effect but it's not sorting.

 

NOTE: I've tried SORT_NUMERIC - the problem seems to be that it only sorts the first number before the comma (,)..

 

Any help is much appreciated. Thanks.

That's not technically sorting "numbers" there are commas. If you strip the numbers of those, it should sort properly.

[DamienRoche]

So is there not a way to just sort the number and take into account the comma?

<pre>
<?php
$fig = array (	
	'1,249', '33,182', '33182',
	'9,333', '3,981,847', '9,149',
	'3,294', '17,928', '1,413', '2,994'
);
$fig = array_map(create_function('$num', 'return preg_replace("/\D/", "", $num);'), $fig);
sort($fig);
$fig = array_map(create_function('$num', 'return number_format($num);'), $fig);
print_r($fig);
?>
</pre>

Thanks! Works perfectly and you've introduced me to a few new functions.
