[SOLVED] advanced array sorting

[surion]

hi, i got an array containing arrays, wich should get sorted one way or another. this is what the array looks like (var_dump of it)

 

array(234) {
  [0]=>
  array(1) {
    [746]=>
    string(15) "X some alphanumeric data"
  }
  [1]=>
  array(1) {
    [747]=>
    string(15) "F some alphanumeric data"
  }
  [2]=>
  array(1) {
    [748]=>
    string(17) "E some alphanumeric data"
  }
  [3]=>
  array(1) {
    [749]=>
    string(11) "ER some alphanumeric data"
  }
  [4]=>
  array(1) {
    [750]=>
    string(10) "some alphanumeric data"
  }
  [5]=>
  array(1) {
    [751]=>
    string(22) "lsqmdkd some alphanumeric data"
  }
}

 

the big array should have the "smaller arrays" in alphabetical order of the string values inside the smaller arrays, is there a possibility to fix this easy? by the way, it is of great importance that the key and the string of the smaller arrays stay together

 

i can't sort the data before it goes into the array, because i don't put it in there myself. i just get the array as it is

 

*edit* dunno if i explained good enough, but this is what it should look like after the sorting:

 

array(234) {
  [0]=>
  array(1) {
    [748]=>
    string(17) "E some alphanumeric data"
  }
  [1]=>
  array(1) {
    [749]=>
    string(11) "ER some alphanumeric data"
  }
  [2]=>
  array(1) {
    [747]=>
    string(15) "F some alphanumeric data"
  }
  [3]=>
  array(1) {
    [751]=>
    string(22) "lsqmdkd some alphanumeric data"
  }
  [4]=>
  array(1) {
    [750]=>
    string(10) "some alphanumeric data"
  }
  [5]=>
  array(1) {
    [746]=>
    string(15) "X some alphanumeric data"
  }
}

try[code[<?php
function my_comp($a, $b){
foreach ($a as $v) $x = strtolower($v);
foreach ($b as $v) $y = strtolower($v);
if ($x > $y) return 1;
if ($x == $y) return 0;
return -1; 
}

$a = array(array(746=>"X some alphanumeric data"),
	   array(747=>"F some alphanumeric data"),
	   array(748=>"E some alphanumeric data"),
	   array(749=>"ER some alphanumeric data"),
	   array(750=>"some alphanumeric data"),
	   array(751=>"lsqmdkd some alphanumeric data")
  );
usort($a, 'my_comp');
print_r($a);
?>
