Some days before came across an interview, where in I have to face the basics for Team Leader.

so my friends beware hope you will find this functions useful. Although there are short ways but still some people want to take the same long ways.

Here are the functions :

//Max element of an array

function max_array($array){
$max = $array[0];
for($i=0;$i < count($array);$i++){
if($array[$i] > $max){
$max = $array[$i];
}
}
return $max;
}

//min of an array

function min_array($array){
$min = $array[0];
for($i=0;$i < count($array);$i++){
if($array[$i] < $min){
$min = $array[$i];
}
}
return $min;
}

//sort an array using bubble sort

function array_sort($array){
for($i=0; $i < count($array); $i++){
for($j=0; $j < count($array)-1; $j++){
if($array[$j] > $array[$j+1]){
$temp = $array[$j+1];
