Remove duplicate keys from array

Question

I'm getting strange behavior of array. I am getting an array with duplicate keys. I checked that this is due to the Datatype of the keys. How can i make it unique. This is the array:

Array
(
    [1811258] => stdClass Object
        (
            [status] => true
            [count] => 1
            [price] => 2501
            [attributes] => 
            [groupid] => 2400
            [subgroupid] => bux_364905
            [desc] => GE Refrigerator - Side by Side GC5SHEXNQ..
            [id] => 1811258
        )

    [1812193] => stdClass Object
        (
            [status] => true
            [count] => 1
            [price] => 293
            [attributes] => 
            [groupid] => 2410
            [subgroupid] => 0
            [desc] => STAINLESS STEEL DOUBLE BOWL - 20 GAUGE
            [id] => 1812193
        )

    [1811258] => stdClass Object
        (
            [status] => 1
            [count] => 1
            [price] => 2501
            [attributes] => 
            [groupid] => 2400
            [subgroupid] => bux_364905
            [desc] => GE Refrigerator - Side by Side GC5SHEXNQ..
            [id] => 1811258
        )

    [1852936] => stdClass Object
        (
            [status] => 1
            [count] => 1
            [price] => 525
            [attributes] => 
            [groupid] => 2489
            [subgroupid] => 0
            [desc] => 
            [id] => 1852936
        )

    [1812193] => stdClass Object
        (
            [status] => 1
            [count] => 1
            [price] => 293
            [attributes] => 
            [groupid] => 2410
            [subgroupid] => 0
            [desc] => STAINLESS STEEL DOUBLE BOWL - 20 GAUGE
            [id] => 1812193
        )

)

I have tried array_key_exists() function to check:

$saved=(array)json_decode($reviewdata->options);
 foreach($optioncodes as $key=>$optioncode){
        $option=$wpdb->get_row("SELECT * from {$prefix}builder_phaseplanoption where OptionCode='{$optioncode}' and SubdivisioNID='{$subdivision}'");
        if($option){
            if(array_key_exists($option->ID,$saved))
                $saved[$option->ID]=(object)array('status'=>true,'count'=>1,'price'=>$option->UnitPrice,'attributes'=>'','groupid'=>$option->OptionGroupID,'subgroupid'=>$option->Sub_OptionGroupID,'desc'=>$option->OptionLongDesc,'id'=>$option->ID);
        }
    }

But no effect.I also tried to change the data type.Like this

$optid=(string)$option->ID; // now this shoud string but no effect
                    $saved[$optid]=(object)array('status'=>true,'count'=>1,'price'=>$option->UnitPrice,'attributes'=>'','groupid'=>$option->OptionGroupID,'subgroupid'=>$option->Sub_OptionGroupID,'desc'=>$option->OptionLongDesc,'id'=>$option->ID);

I know this is due to the problem that keys in the saved array are strings while the new keys are numbers. How can i convert them to the same type.

Thanks in advance.

"I am getting an array with duplicate keys." -- there are two possibilities: either you have found a serious bug in PHP, which is practically impossible, or there is a problem in your code. — axiac

I have done this but i am not sure if it is the correct way to do this. If there is any better way then please give your suggestions. I changed the data type and create a new array.And it remove the duplicate values.

$newsaved=array();
foreach($saved as $key=>$value){
    $stroptid=(string)$key;
    $newsaved[$stroptid]=$value;
}

Now this is the output

Array
(
    [1811258] => stdClass Object
        (
            [status] => 1
            [count] => 1
            [price] => 2501
            [attributes] => 
            [groupid] => 2400
            [subgroupid] => bux_364905
            [desc] => GE Refrigerator - Side by Side GC5SHEXNQ..
            [id] => 1811258
        )

    [1812193] => stdClass Object
        (
            [status] => 1
            [count] => 1
            [price] => 293
            [attributes] => 
            [groupid] => 2410
            [subgroupid] => 0
            [desc] => STAINLESS STEEL DOUBLE BOWL - 20 GAUGE
            [id] => 1812193
        )

    [1852936] => stdClass Object
        (
            [status] => 1
            [count] => 1
            [price] => 525
            [attributes] => 
            [groupid] => 2489
            [subgroupid] => 0
            [desc] => 
            [id] => 1852936
        )

The JSON you posted in the question's comments contains invisible characters and it's invalid. I wonder how you managed to decode it. json_decode() refuses to decode it for me: 3v4l.org/cg5WC
