PHP max() function

The PHP math max function is used to return the highest value from a set of expressions.

$val2=max(1,2);

$val3=max('abcd','dsef','fgre');

$val4=max(array(1,-2,5,8));

echo "max value of <b>max(34,4,32,6,78)</b> is <b>$val1</b> <br />";

echo "max value of <b>max(1,2)</b> is <b>$val2</b> <br />";

echo "max value of <b>max('abcd','dsef','fgre')</b> is <b>$val3</b> <br />";

echo "max value of <b>max(array(1,-2,5,8))</b> is <b>$val4</b> <br />";

?>

Output



PHP min() function

The PHP math min function is used to return the minimum value from a set of expressions.

$val1=min(34,4,90,6,78);
$val2=min(1,2);
$val3=min('abcd','dsef','fgre');
$val4=min(array(1,-2,5,8));
echo "min value of <b>min(34,4,32,6,78)</b> is <b>$val1</b> <br />";
echo "min value of <b>min(1,2)</b> is <b>$val2</b> <br />";
echo "min value of <b>min('abcd','dsef','fgre')</b> is <b>$val3</b> <br />";
echo "min value of <b>min(array(1,-2,5,8))</b> is <b>$val4</b> <br />";
?>

Output
