What comma in big numbers? Numbers aren't supposed to have commas. If it has a 
comma it's a string.

Snippet from the manual "The value is given by the initial portion of the 
string. If the string starts with valid numeric data, this will be the value 
used.". As a comma is not valid numeric data, it and everything after, will 
be ignored.

[PHP] SORT_NUMERIC

[Jim Long]

Hi,

Does anyone know how to make the flag "sort_numeric" work? 
Will it work with asort?  

asort ($numeric_array, SORT_NUMERIC);
I've tried this but it looks like it's having problems with the comma in
big numbers. 
I'm not absolutely sure, but it looks like it's ignoring everything
after a comma when it sorts.

TIA,
Jim Long

BTW: asort is the one I need as I must maintain the keys

[PHP] PHP SORT_NUMERIC

[Jim Long]

Hi,

I've got to sort the $numeric_arry

This doesn't seem to work:
sort ($numeric_array, SORT_NUMERIC);
I think its sorting $key

asort ($numeric_array, SORT_NUMERIC);
sorts as a string


THANKS AGAIN IN ADVANCE,
Jim Long
