PHP - copy an array does not work

Question

Hello!

I have an array:

print_r($resultArray);

Array
(
    [AB34] => Array
        (
            [a] => 13
            [b] => 10
            [c] => 3
            [d] => 88
            [e] => 73
        )
    ...
)

And I want to copy this array into another one:

$resArray[] = $resultArray;
print_r($resArray);

->

Array
(
    [0] => 1
)

So the new array $resArray does not have the content of $resultArray. What needed to be done to solve this?

Best Regards.

UPDATE: I have to copy the $resultArray into $resArray (that's an easy example), because $resultArray will change and I need the data in a $resArray with index, so $resArray[0] the first $resultArray, $resArray[1] the second full value of the $resultArray, ... Some code (only a simple example!):

$resArray[0] = $resultArray;
... calculations on $resultArray ...
$resArray[1] = $resultArray;
... calculations on $resultArray ...
$resArray[2] = $resultArray;
... calculations on $resultArray ...

Answer 1

$resArray = $resultArray;

... also use print_r($var, TRUE); in order to get the full contents of the variable.

Answer 2

Try without brackets like this:

$resArray = $resultArray;
print_r($resArray);

Answer 3

I can only guess you have a small syntax error somewhere. My testcase works as expected:

$resultArray = array(
    'AB34' => array(
        'a' => 13,
        'b' => 10,
        'c' => 3,
        'd' => 88,
        'e' => 73
    )
);

echo '<pre>';
echo "Printing \$resultArray\n";
print_r($resultArray);

$resArray[] = $resultArray;
$resArray[] = $resultArray;
$resArray[0]['AB34']['c'] = 'Penguins are neat';

echo "\n\nPrinting \$resArray\n";
print_r($resArray);

Returns

            [e] => 73
        )
