I'm tryin to merge an array that I have when it is being created through a function
I have a function, and it returns an array.
class myarray
{
public function getAr($id)
{
// mysql query
while($dd= $database->fetch(PDO::FETCH_ASSOC))
{
$data[] = $dd; //there's values in the array when its being populated through the function of the while loop
}
return $data;
}
public function get3($id)
{
// mysl query
while($dd= $database->fetch(PDO::FETCH_ASSOC))
{
$data[] = $dd; //there's values in the array when its being populated through the function of the while loop
}
return $data;
}
}
How come I tried to merge together the array:
$get = new myarray();
while($row = $fet->fetch(PDO::FETCH_ASSOC))
{
$arrayAr = $get->getAr($id);
$array3 = $get->get3($id);
$new_array = array_merge($arrayAr ,$array3); //this gives me the error
print_r($arrayAr); //displays array
}
print_r($arrayAr); //displays nothing, why is that?
It says that its not an array?
array_merge() [function.array-merge]: Argument #1 is not an array
But I can print_r($arrayAr); and its like an array inside the while loop, but it doesn't display anything outside of it?
when I tried this...
$new_array = array_merge((array)$arrayAr ,(array)$array3);
It doesn't display an error, but it isn't merged either.
Help?
Thanks
$new_arrayeach time. Problem 3: variables could return empty (i.e.,get3can return undefined if there's nothing to loop through). – jeremyharris Sep 3 '12 at 18:50$arrayAr = array();right before the loop, otherwise it won't know it's an array when you try and use merge the first time. – jeremyharris Sep 3 '12 at 19:16$dataisn't instantiated and the while loops aren't running (because$databasedoesn't exist?). Turn error reporting to all so you can see all errors. – jeremyharris Sep 3 '12 at 19:30
