max
Find highest value
mixed **max** mixed $value mixed $values
Alternative signature (not supported with named arguments):
mixed **max** array $value_array
If the first and only parameter is an array,
returns the highest value in that array. If at least two parameters are
provided, returns the biggest of these values.

For instance, a non-numeric will be compared to an as though it were , but multiple non-numeric values will be compared alphanumerically. The actual value returned will be of the original type with no conversion applied. standard comparison rules

returns the parameter value considered "highest" according to standard
comparisons. If multiple values of different types evaluate as equal (e.g.
and ) the first provided to the function will be returned.

**Voorbeeld: Example uses of **
<?php
echo max(2, 3, 1, 6, 7), PHP_EOL; // 7
echo max(array(2, 4, 5)), PHP_EOL; // 5
// Here we are comparing -1 < 0, so 'hello' is the highest value
echo max('hello', -1), PHP_EOL; // hello
// With multiple arrays of different lengths, max returns the longest
$val = max(array(2, 2, 2), array(1, 1, 1, 1)); // array(1, 1, 1, 1)
var_dump($val);
// Multiple arrays of the same length are compared from left to right
// so in our example: 2 == 2, but 5 > 4
$val = max(array(2, 4, 8), array(2, 5, 1)); // array(2, 5, 1)
var_dump($val);
// If both an array and non-array are given, the array will be returned
// as comparisons treat arrays as greater than any other value
$val = max('string', array(2, 5, 7), 42); // array(2, 5, 7)
var_dump($val);
// If one argument is NULL or a boolean, it will be compared against
// other values using the rule FALSE < TRUE regardless of the other types involved
// In the below example, -10 is treated as TRUE in the comparison
$val = max(-10, FALSE); // -10
var_dump($val);
// 0, on the other hand, is treated as FALSE, so is "lower than" TRUE
$val = max(0, TRUE); // TRUE
var_dump($val);
