[SOLVED] sort() function not sorting numbers correctly

[Someone789]

Hi,

 

Basically, I'm using the rsort() function to sort a number of arrays from the largest number to the smallest number. However, it isn't working correctly.

 

I have a $numbers array, which has 25 arrays of numbers within it. Just to view what $numbers[1] looked like, I wrote this:

print_r($numbers[1]);

 

Yields:

Array ( [0] => 600072 [1] => 336099 [2] => 246016 [3] => 214041 [4] => 191549 [5] => 156316 [6] => 144808 [7] => 140885 [8] => 130908 [9] => 122126 [10] => 117487 [11] => 99993 [12] => 99763 [13] => 99041 [14] => 98775 [15] => 97630 [16] => 91849 [17] => 85420 [18] => 83651 [19] => 83329 [20] => 78742 [21] => 73963 [22] => 68829 [23] => 68082 [24] => 67398 [25] => 67198 [26] => 66813 [27] => 66319 [28] => 64493 [29] => 62050 [30] => 61954 [31] => 61576 [32] => 59285 [33] => 59120 [34] => 58611 [35] => 58052 [36] => 57963 [37] => 111 [38] => 55476 [39] => 54523 [40] => 51975 [41] => 50861 [42] => 49765 [43] => 222 [44] => 333 [45] => 47219 [46] => 47036 [47] => 46165 [48] => 44149 [49] => 44095 [50] => 56976 [51] => 47751 [52] => 47233 ) 

 

As you can see, the array is filled with some assorted numbers, from 111 to 600,072. I need the number sets from all 25 $number arrays to be ordered from largest to smallest, so I made this adjustment to my script and again kept in the print_r code to view what the new $numbers[1] array looked like:

for ($y = 0; $y <= 24; $y++) {

rsort($numbers[$y]);

}

print_r($numbers[1]);

 

Which yielded:

Array ( [0] => 99993 [1] => 99763 [2] => 99041 [3] => 98775 [4] => 97630 [5] => 91849 [6] => 85420 [7] => 83651 [8] => 83329 [9] => 78742 [10] => 73963 [11] => 68829 [12] => 68082 [13] => 67398 [14] => 67198 [15] => 66813 [16] => 66319 [17] => 64493 [18] => 62050 [19] => 61954 [20] => 61576 [21] => 600072 [22] => 59285 [23] => 59120 [24] => 58611 [25] => 58052 [26] => 57963 [27] => 56976 [28] => 55476 [29] => 54523 [30] => 51975 [31] => 50861 [32] => 49765 [33] => 47751 [34] => 47233 [35] => 47219 [36] => 47036 [37] => 46165 [38] => 44149 [39] => 44095 [40] => 336099 [41] => 333 [42] => 246016 [43] => 222 [44] => 214041 [45] => 191549 [46] => 156316 [47] => 144808 [48] => 140885 [49] => 130908 [50] => 122126 [51] => 117487 [52] => 111 )

 

However, as you can obviously see, this did not sort the numbers in descending order according to value, but instead by simply the first digit in the number. The largest number in the array - 600,072 - is in the middle with the rest of the 6s instead of out in front.

 

So, my question is: How can I sort these numbers so that their *values* are placed in descending order, and not just be ordered by their leading digit?

 

Many thanks in advance!

rsort($numbers);
print_r($numbers);

Right, don't need the FOR function, sort() cycles through the whole of the array already. I made the same mistake first time I used sort() too.

Works now, thanks!
