Math functions max() to get highest numbers between several numbers or array of numbers

max(): Maximum number

echo max(4,8,2); // 8 
echo "<br>";
echo max(5,-1,0); // 5
echo "<br>";
echo max(2,0,-3); // 2
echo "<br>";
echo max(array(4,6,1)); // 6
echo "<br>";

echo max('plus2net',5,-2);// plus2net
echo "<br>";
echo max('abcd',5,0);// abcd
echo "<br>";
echo max('hello', 1); // hello

echo "<br><BR>";
echo max(0, 'hello');     // hello
echo "<br>";
echo max('hello', 0);     // hello

Syntax

MAX(value1,value2,value3....);

We can get maximum value or highest number between two variables or two numbers by using max function. We can use more than two numbers also. Here is the code.

<?Php
echo max(5,25,6,-22,-66); // Output is 25 
?>

Max with String

We can find out maximum by comparing one string wth a number. Here string will be treated as 0 and then compared.

<?Php
echo max(-2.5,'plus2net'); // Output  plus2net
echo max(0,'plus2net'); // Output is 0, when values are equal the order decides the output 
echo max(3,'plus2net');  //Output is 3
?>

Max with array

<?Php
echo max(array(3,15,-5)); //Output is 15
?>

Example: Finding Maximum String Length

$result = max(strlen('apple'), strlen('banana'), strlen('cherry'));
echo $result;  // Output: 6

Example: Maximum Value in an Array

$array = [10, 50, 30, 90, 40];
echo max($array);  // Output: 90

Example: Mixed Data Types

$result = max(10, 'apple');
echo ($result);  // Output: apple (as it compares lexicographically)
