See if you can do this using arrays and for loops.
For example:
$sample = array( 135, 2.4, 2.67, 1.23, 332, 2, 1.02);
$output = get_max_and_min($sample);
var_dump($output);
//$output should be equal to array('max' => 332, 'min' => 1.02);-->
<?php
function get_max_and_min($arr)
{
$min = $arr[0];
$max = $arr[0];
for ($i = 0; $i < count($arr); $i++) {
if ($min > $arr[$i]) {
$min = $arr[$i];
}
if ($max < $arr[$i]) {
$max = $arr[$i];
}
}
$min_max = array('min' => $min, 'max' => $max);
return $min_max;
}
$sample = array(135, 2.4, 2.67, 1.23, 332, 2, 1.02);
$output = get_max_and_min($sample);
var_dump($output);
?>
</body>
<html>
<?php
$sample = array(135, 2.4, 2.67, 1.23, 332, 2, 1.02);
function get_max_and_min($sample)
{
$output = array();
$max = 0;
$min = 0;
foreach ($sample as $key) {
if ($key > $max) {
$max = $key;
$output['max'] = $max;
} else {
if ($key < $max) {
$min = $key;
$output['min'] = $min;
}
}
}
var_dump($output);
}
get_max_and_min($sample);
