Question

I asking about this case(replace item by position : highest with lowest etc.. ):

my inputs:

// case1:
array('orange','blue','red');

// case2:
array('orange','blue','red','white');

should get outputs:

// case1:
array('red','blue','orange');

// case2:
array('white','red','blue','orange');

its can be done by – but i am looking for more shorter way:

function myReplaceArr(array $arr){     
 $len=count($arr);  
 $loopLen=(int)($len/2);    
 for($i=0;$i<$loopLen;$i++){
   $temp=$arr[$i];
   $arr[$i]=$arr[$len-$i-1];
   $arr[$len-$i-1]=$temp;
 }
 return $arr;
}
var_export(myReplaceArr(array('orange','blue','red')));
var_export(myReplaceArr(array('orange','blue','red','white')));

Thats called array_reverse();

$array_1 = array('orange','blue','red');
$array_2 = array('orange','blue','red','white');

$array_1_new = array_reverse($array_1);
$array_2_new = array_reverse($array_2);
