Error merging arrays in PHP -

i have nested arrays , want append content of 1 array when keys match. here function instead of appending replacing.

function mergearrays($arr, $ins) {     if(is_array($arr))     {         if(is_array($ins))              foreach($ins $k=>$v)             {                 if(isset($arr[$k])&&is_array($v)&&is_array($arr[$k]))                 {                     $arr[$k] = mergearrays($arr[$k], $v);                 }                 else                  {                     // new loop :)                     // while (isset($arr[$k]))                         // $k++;                     // here want append instead of add                     $arr[$k] = $v;                 }             }     }     else if(!is_array($arr)&&(strlen($arr)==0||$arr==0))     {         $arr=$ins;     }     return($arr); } 

any recommendations?

thanks

you can merge entries either adding arrays together, or using array_merge merge arrays new one.

any reason you're not using array_merge_recursive solve without custom code?
