PHP Sort Array without using built in function
We can write our own program to sort array in PHP without using built in functions like – sort(), rsort().
Example
<?php
$array = array(21, 9, 10, 11, 9);
echo "Array Unsorted<br />";
print_r($array);
for($i = 0; $ < count($array); $i ++) {
for($j = 0; $j < count($array)-1; $j ++){
if($array[$j] > $array[$j+1]) {
$temp = $array[$j+1];
$array[$j+1]=$array[$j];
$array[$j]=$temp;
}
}
}
echo "Array After Sorting: ";
echo "<br />";
print_r($array);
?>
