Insertion sort php - php

Question

Have someone an idea why the programm doesn't enter in the function?
This is a simple insertion sort algorithm.
<?php
function insert($my_array)
{
for($i=0;$i<count($my_array);$i++){
$val = $my_array[$i];
$j = $i-1;
while($j>=0 && $my_array[$j] > $val){
$my_array[$j+1] = $my_array[$j];
$j--;
}
$my_array[$j+1] = $val;
}
return $my_array;
$test_array = array(3, 0, 2, 5, -1, 4, 1);
echo "Original Array :\n";
echo implode(', ',$test_array );
echo "\nSorted Array :\n";
print_r(insert($test_array));
?>

Answer 1

} is missing try now
function insert($my_array)
{
for($i=0;$i<count($my_array);$i++){
$val = $my_array[$i];
$j = $i-1;
while($j>=0 && $my_array[$j] > $val){
$my_array[$j+1] = $my_array[$j];
$j--;
}
$my_array[$j+1] = $val;
}
return $my_array;
}
$test_array = array(3, 0, 2, 5, -1, 4, 1);
echo "Original Array :\n";
echo implode(', ',$test_array );
echo "\nSorted Array :\n";
print_r(insert($test_array));
OutPut : Original Array : 3, 0, 2, 5, -1, 4, 1 Sorted Array : Array ( [0] => -1 [1] => 0 [2] => 1 [3] => 2 [4] => 3 [5] => 4 [6] => 5 )

Answer 2

$data_set = [3,44,38,5,15,26,27,2,46,4];
function insertion_sort($data_set){
$number_of_items = count($data_set);
for($i = 0; $i <= $number_of_items - 2; $i++){
$k = $i;
for($j = $i + 1; $j > 0; $j--){
if($data_set[$j] < $data_set[$k]){
$temp = $data_set[$j];
$data_set[$j] = $data_set[$k];
$data_set[$k] = $temp;
}
if($k > 0 )
$k--;
}
}
return $data_set;
}
echo '<pre>';
print_r(insertion_sort($data_set));
echo '</pre>';
