Hello all,
For anyone who is interested here's the answer.
$keylist = array_keys($this->TableArrayRes[0]);
foreach ($this->TableArrayRes as $key => $row) {
foreach($keylist as $arraykey){
eval("\$$arraykey" . '[$key]=$row[\''. $arraykey .'\'];');
}
}
eval('array_multisort(' . $this->TableArraySort . '$this->TableArrayRes);');

| Hello all,
|
| can someone give me an idea on how to sort a 2 dimentional array (table).
|
| $array = array('Fruit' => 'Apple', 'Price' => 1);
| $array = array('Fruit' => 'orange', 'Price' => 2);
|
| Now this is relatively simple to do when you know the structure of the
| array. However, I am trying to write a function that will sort a two
| dimentional array whose structure I do not know beforehand.
|
|
| based on the example below for array_multisort() on php's documentation
|
| <?php
| // Obtain a list of columns
| foreach ($data as $key => $row) {
| $volume[$key] = $row['volume'];
| $edition[$key] = $row['edition'];
| }
|
| // Sort the data with volume descending, edition ascending
| // Add $data as the last parameter, to sort by the common key
| array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $data);
| ?>
|
| I was looking a something along these lines:
|
| ex.
|
| function arraysort ($array,$param){
| $keylist = array_keys($array[0]);
|
| foreach ($array as $key => $row) {
| foreach($keylist as $arraykey){
|
| $$arraykey[$key] = $row[$arraykey];
| }
| }
| array_multisort("$param", $array);
| }
|
| arraysort($somearray,"$firstcol, SORT_DESC, $secondcol, SORT_ASC");
|
|
| my first problem lies with $$arraykey[$key] and what I need is a hint on
how
| to create a dynamically named array.
|
| any suggestions?
|
| thanks,
|
| James
