Sort float values from Array

[Reignfire]

Hi,

 

This is the output from a var_dump($array); command:

array (size=381)
  0 => 
    array (size=2)
      'Name' => string 'apple' (length=6)
      'Number' => float 0.368844763
  1 => 
    array (size=2)
      'Name' => string 'Blueberry' (length=
      'Number' => float 5.59E-6
  2 => 
    array (size=2)
      'Name' => string 'Cinnamon' (length=5)
      'Number' => float -0.0006947
  3 => 
    array (size=2)
      'Name' => string 'Date' (length=10)
      'Number' => float 0.001584453
...
...
...

I want to sort this array from the highest 'Number' float value to the smallest. I tried sorting it with rsort($array,SORT_NUMERIC); but that doesn't give the correct output.

 

What kind of 'sort' should i use to do this?

the most straightforward method would be to use usort() - http://us3.php.net/usort and write a function that compares the 'Number' elements of the arrays.

 

another method would be to use array_multisort()
