Combine two arrays

0 votes

I have two arrays like this:

array( 
'11' => '11',
'22' => '22',
'33' => '33',
'44' => '44'
);

array( 
'44' => '44',
'55' => '55',
'66' => '66',
'77' => '77'
);

I want to combine these two arrays such that it does not contains duplicate and as well as keep their original keys. For example, Output should be:

array( 
'11' => '11',
'22' => '22',
'33' => '33',
'44' => '44',
'55' => '55',
'66' => '66',
'77' => '77'
);

I have tried this but it is changing their original keys:

$output = array_unique( array_merge( $array1 , $array2 ) );

Can someone please help me in doing this?
