WeberDev.com -> PHP Manual -> Find highest value

Description

mixed max ( array $values )

mixed max ( mixed $value1 , mixed $value2 [, mixed $value3... ] )

If the first and only parameter is an array, max() returns the highest value in that array. If at least two parameters are provided, max() returns the biggest of these values.

Note: PHP will evaluate a non-numeric string as 0 if compared to integer, but still return the string if it's seen as the numerically highest value. If multiple arguments evaluate to 0, max() will return a numeric 0 if given, else the alphabetical highest string value will be returned.

Parameters

values: An array containing the values.

Return Values

max() returns the numerically highest of the parameter values.

Examples

Example #1 Example uses of max()

 <?php
echo max(1, 3, 5, 6, 7);  // 7
echo max(array(2, 4, 5)); // 5

echo max(0, 'hello');     // 0
echo max('hello', 0);     // hello
echo max(-1, 'hello');    // hello

// With multiple arrays, max compares from left to right
// so in our example: 2 == 2, but 4 < 5
$val = max(array(2, 4, 8), array(2, 5, 7)); // array(2, 5, 7)

// If both an array and non-array are given, the array
// is always returned as it's seen as the largest
$val = max('string', array(2, 5, 7), 42);   // array(2, 5, 7)
?>
