Here is my code
<?php
rsort($max_k);
for($i = 0; $i < 3; $i++) // Only loop 10 times.
//echo $max_k[$i] . "<br>";
$newArray = array_slice($max_k, 0, 10, true);
echo ($newArray) ;
?>

Take advantage of Debugger Class
App::uses('Debugger','Utility');
$array = array(1,2,3,4,5,6,7,8,9,10,11,12,13);
$arrayToString = Debugger::exportVar($array);
echo $arrayToString;
//Result:
//array( (int) 0 => (int) 1, (int) 1 => (int) 2, (int) 2 => (int) 3, (int) 3 => (int) 4, (int) 4 => (int) 5 )

Please try using print_r($newArray)
you may use foreach() for accessing individual elements as needed according to your program logic. Hope this is enough for the task. Do comment if you need anything else.

I used the following test code:
$max_k=array(1,2,3,4,5,6,7,8,9,10,11,12,13);
$newArray=array_slice($max_k, 0, 10, true);
In PHP you can produce a readable output from data structures in different ways. One of the oldest functions is print_r (php.net/manual/en/function.print-r.php):
print_r($newArray);
produces the output:
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
[5] => 6
[6] => 7
[7] => 8
[8] => 9
[9] => 10
)
The next possibility is var_dump (php.net/manual/en/function.var-dump.php), which takes one or more variables to display with value and structure:
var_dump($newArray);
One of my favourites is var_export (php.net/manual/en/function.var-export.php):
var_export($newArray);
which creates:
array (
0 => 1,
1 => 2,
2 => 3,
3 => 4,
4 => 5,
5 => 6,
6 => 7,
7 => 8,
8 => 9,
9 => 10,
)
Best feature of var_export is, that it supports a second boolean parameter. When set to true, it will return the readable version as a string. So you can for example log the output to a file instead of printing:
$output=var_export($newArray, true);
print $output;
Result:
array (
0 => 1,
1 => 2,
2 => 3,
3 => 4,
4 => 5,
5 => 6,
6 => 7,
7 => 8,
8 => 9,
9 => 10,
)
Hope that helps.
PS: The php.net site has a cool feature: if you enter a search string after the php.net like:
php.net/var_dump
you will be sent to the man page of that function, if it exists or see a list of similar results, if there is no function with that name :)
