Rank function (Like MS Excel)

General PHP Help
#1

I am curious to know if there is a easy way to rank values using php. I have googled for a while and can’t seem to turn up any relevant results. I have a few dynamic values, that I need to rank by the highest value.
Example:

<table>
<tr>
<th>Total Call Attempts</th><th>Rank</th>
</tr>
<tr>
<td>5026200</td><td>Rank</td>
</tr>
<tr>
<td>5455370</td><td>Rank</td>
</tr>
<tr>
<td>2156424</td><td>Rank</td>
</tr>
</table>

Do any of you have any ideas? Any help is appreciated.
TIA

Define rank.

#3

You could try using rsort() or some similar function if you have the information in an array…

#4

By rank I would like to take a range of values from the db, and assign a rank.
For example
Let’s say i have a field called Total Call AttemptsI would like to rank by the amount of call attempts.

Total Call Attempts | Rank

1000 | 1
900 | 2
800 | 3

I hope this clarifies things. Thanks in advance.

Ahhh. Look at the SQL keywords ORDER BY. If you are using MySQL see
http://dev.mysql.com/doc/mysql/en/Sorting_rows.html

#6

Order by would work if the “Rank” field existed in the database, however it does not. I would like to (hopefully) use a php function to define rank dynamically.
I hope this helps.

#7

Guess you could use the max() mathmatical function.

I would put it all into an array and use one of the array sorting functions to sort it.

Manual -> Search -> functions ->type array (will give you all the array functions - right before user comments - so you can also see how to create one) Or http://www.php.net/manual/en/ref.array.php :)
