Re: [PHP] ksort by value

That works, thanks.
I think I'll put this into MySQL eventually. "sort by" key would do it 
better, and I will need to more.

http://php.net/manual/en/array.sorting.php is pretty clear. But my
problem is that sort ($freq) destroyed my key.

Did you actually read it? There's a table on that page that summarises exactly 
what each sorting function does, with a column for whether they "maintain key 
association."

In this case you want http://php.net/asort

If you want to perform a count on all the unique values (in SQL Terms a
group by and a count) use
http://php.net/manual/en/function.array-count-values.php  instead.

ksort sorts by key, if you want by value, look at sort.

are asc, krsort and rsort are desc equivalents.

I'm beginning to think I should plug this into a MySQL table, where I 
would be at home.
But right now, I'll be stubborn and go read 
http://php.net/manual/en/array.sorting.php.

[PHP] ksort by value

[John Taylor-Johnston]

Hi,



If I have my terminology right, ksort($freq) sorts the array by the key. 
And that works fine.

But I would also like to sort by value to see which words are more frequent.
There is no |ascending/descending option to ksort?|

Thanks,
John
