Question

I have a small task in php. I have a simple array.

Array
(
    [0] => 50
    [1] => 100
    [2] => 150

)

Is there a php built in function which i can use so that it can return true or false, accordingly if array is already sorted or not, Or any other php script for this, no loops. I know it is easy with loops and conditions.

Answer 1

Here, you can try with this code:

<?php

$sort = array(
    0 => 50,
    1 => 100,
    2 => 150
);

$default = $sort;
sort($sort);

$flag = true;
foreach($sort as $key=>$value)
    if($value!=$default[$key])
        $flag = false;  

if($flag)
    echo "Already sorted";  
else
    echo "Not Already sorted";  
?>
