I have an array called "$myarray", which looks like this:
[0] => Array
(
[PrinterID] => 4
[PrinterName] => PRT04_GL
[UserID] => 1
[isDefaultPrinter] => 0
[isMapped] => 0
)
[1] => Array
(
[PrinterID] => 1
[PrinterName] => PRT01_Zentral
[UserID] =>
[isDefaultPrinter] => 0
[isMapped] => 0
)
[2] => Array
(
[PrinterID] => 2
[PrinterName] => PRT02_BH
[UserID] =>
[isDefaultPrinter] => 0
[isMapped] => 0
)
[3] => Array
(
[PrinterID] => 3
[PrinterName] => PRT03_EDV
[UserID] =>
[isDefaultPrinter] => 0
[isMapped] => 1
)
I want to sort the data by ["PrinterName"]. The wanted result would be:
[0] => Array
(
[PrinterID] => 1
[PrinterName] => PRT01_Zentral
[UserID] =>
[isDefaultPrinter] => 0
[isMapped] => 0
)
[1] => Array
(
[PrinterID] => 2
[PrinterName] => PRT02_BH
[UserID] =>
[isDefaultPrinter] => 0
[isMapped] => 0
)
[2] => Array
(
[PrinterID] => 3
[PrinterName] => PRT03_EDV
[UserID] =>
[isDefaultPrinter] => 0
[isMapped] => 1
)
[3] => Array
(
[PrinterID] => 4
[PrinterName] => PRT04_GL
[UserID] => 1
[isDefaultPrinter] => 0
[isMapped] => 0
)
Based on this example I tried the following:
uasort($myarray, 'sort_by_order');
function sort_by_order ($a, $b) {
return $a['PrinterName'] - $b['PrinterName'];
}
This does not work. I get errors like "A non-numeric value encountered ...", of course because my values are strings and the function is for numeric values.
How do I sort the array?
Thank you!
EDIT: I think I did find the solution here. I used this and it seems to work:
uasort($myarray, 'sort_by_order');
function sort_by_order ( $a, $b ) { return strcmp($a['PrinterName'], $b['PrinterName']); }
