here you go

 

 

<?php

global $arrReturn;
$arrReturn = array();
$arrInput = array(0=>array(1, 2, 3, 4, 5, 6, 7,);


function fnSplitArray($arrInput,$intCount)
{
Global $arrReturn;
$arrOutput = array();
$arrOne = array();
$arrTwo = array();
for ($i=0;$i<count($arrInput);$i++)
{
	$arrOne[] = array_splice($arrInput[$i],0,count($arrInput[$i])/2);
	$arrTwo[] = $arrInput[$i];

}
$arrOutput = array_merge($arrOne,$arrTwo);

$arrReturn = $arrOutput;
if ($intCount>count($arrOutput))
{
	fnSplitArray($arrOutput,$intCount);
}
}

fnSplitArray($arrInput,count($arrInput[0]));
print_r($arrReturn);
?>

a little modified

 

global $arrReturn;
$arrReturn = array();
$arrInput = array(0=>array(1, 2, 3, 4, 5, 6, 7,);


function fnSplitArray($arrInput,$intCount)
{
Global $arrReturn;
$arrOutput = array();
$arrOne = array();
$arrTwo = array();
for ($i=0;$i<count($arrInput);$i++)
{
	$arrOne[] = array_splice($arrInput[$i],0,count($arrInput[$i])/2);
	$arrTwo[] = $arrInput[$i];

}
$arrOutput = array_merge($arrOne,$arrTwo);

$arrReturn = $arrOutput;
if ($intCount>count($arrOutput))
{
	fnSplitArray($arrOutput,$intCount);
}
else 
{
	$arrReturn = array();
	foreach ($arrOutput as $strKey => $arrValues)
	{
			array_push($arrReturn,$arrValues[0]);
	}

}
}

fnSplitArray($arrInput,count($arrInput[0]));
print_r($arrReturn);

try

<?php
function new_order($a){
$out = array();
$n = count($a) / 2;
foreach ($a as $k => $v){
	$m = $n;
	$newk = 0;
	while ($k > 0){
		$newk += ($k % 2) * $m;
		$k = (int) $k / 2;
		$m = $m / 2;
	}
	$out[$newk] = $v;
}
ksort($out);
return $out;
}
$a = array(1,2,3,4,5,6,7,;
$b = new_order($a);
print_r($b);
?>

Array ( [0] => Array ( ) [1] => Array ( [0] => 16 ) [2] => Array ( [0] => 8 ) [3] => Array ( [0] => 24 ) [4] => Array ( [0] => 4 ) [5] => Array ( [0] => 20 ) [6] => Array ( [0] => 12 ) [7] => Array ( [0] => 28 ) [8] => Array ( [0] => 2 ) [9] => Array ( [0] => 18 ) [10] => Array ( [0] => 10 ) [11] => Array ( [0] => 26 ) [12] => Array ( [0] => 6 ) [13] => Array ( [0] => 22 ) [14] => Array ( [0] => 14 ) [15] => Array ( [0] => 30 ) [16] => Array ( [0] => 1 ) [17] => Array ( [0] => 17 ) [18] => Array ( [0] => 9 ) [19] => Array ( [0] => 25 ) [20] => Array ( [0] => 5 ) [21] => Array ( [0] => 21 ) [22] => Array ( [0] => 13 ) [23] => Array ( [0] => 29 ) [24] => Array ( [0] => 3 ) [25] => Array ( [0] => 19 ) [26] => Array ( [0] => 11 ) [27] => Array ( [0] => 27 ) [28] => Array ( [0] => 7 ) [29] => Array ( [0] => 23 ) [30] => Array ( [0] => 15 ) [31] => Array ( [0] => 31 ) )

output if enter only 31 number

a little modified

 

global $arrReturn;
$arrReturn = array();
$arrInput = array(0=>array(1, 2, 3, 4, 5, 6, 7,);


function fnSplitArray($arrInput,$intCount)
{
Global $arrReturn;
$arrOutput = array();
$arrOne = array();
$arrTwo = array();
for ($i=0;$i<count($arrInput);$i++)
{
	$arrOne[] = array_splice($arrInput[$i],0,count($arrInput[$i])/2);
	$arrTwo[] = $arrInput[$i];

}
$arrOutput = array_merge($arrOne,$arrTwo);

$arrReturn = $arrOutput;
if ($intCount>count($arrOutput))
{
	fnSplitArray($arrOutput,$intCount);
}
else 
{
	$arrReturn = array();
	foreach ($arrOutput as $strKey => $arrValues)
	{
			array_push($arrReturn,$arrValues[0]);
	}

}
}

fnSplitArray($arrInput,count($arrInput[0]));
print_r($arrReturn);

 

why modified???

how to let print_r($array) in a proper way?

 

which this ...very unreadable

Array ( [0] => Array ( ) [1] => Array ( [0] => 16 ) [2] => Array ( [0] => 8 ) [3] => Array ( [0] => 24 ) [4] => Array ( [0] => 4 ) [5] => Array ( [0] => 20 ) [6] => Array ( [0] => 12 ) [7] => Array ( [0] => 28 ) [8] => Array ( [0] => 2 ) [9] => Array ( [0] => 18 ) [10] => Array ( [0] => 10 ) [11] => Array ( [0] => 26 ) [12] => Array ( [0] => 6 ) [13] => Array ( [0] => 22 ) [14] => Array ( [0] => 14 ) [15] => Array ( [0] => 30 ) [16] => Array ( [0] => 1 ) [17] => Array ( [0] => 17 ) [18] => Array ( [0] => 9 ) [19] => Array ( [0] => 25 ) [20] => Array ( [0] => 5 ) [21] => Array ( [0] => 21 ) [22] => Array ( [0] => 13 ) [23] => Array ( [0] => 29 ) [24] => Array ( [0] => 3 ) [25] => Array ( [0] => 19 ) [26] => Array ( [0] => 11 ) [27] => Array ( [0] => 27 ) [28] => Array ( [0] => 7 ) [29] => Array ( [0] => 23 ) [30] => Array ( [0] => 15 ) [31] => Array ( [0] => 31 ) )
