min

Find lowest value

mixed **min** mixed $value mixed $values

Alternative signature (not supported with named arguments):

mixed **min** array $value_array

If the first and only parameter is an array, returns the lowest value in that array. If at least two parameters are provided, returns the smallest of these values. min``min

Opmerking: > Values of different types will be compared using the . 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 rulesstring``int``0``string

Let op: > Be careful when passing arguments of different types because can produce unpredictable results. min

value Any value. comparable

values Any values. comparable

value_arrayAn array containing the values.

returns the parameter value considered "lowest" 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. min``0``'abc'

If an empty array is passed, throws a . min``ValueError

**Voorbeeld: Example uses of **

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

// Here we are comparing -1 < 0, so -1 is the lowest value
echo min('hello', -1), PHP_EOL;    // -1

// With multiple arrays of different lengths, min returns the shortest
$val = min(array(2, 2, 2), array(1, 1, 1, 1)); // array(2, 2, 2)
var_dump($val);

// Multiple arrays of the same length are compared from left to right
// so in our example: 2 == 2, but 4 < 5
$val = min(array(2, 4, 8), array(2, 5, 1)); // array(2, 4, 8)
var_dump($val);

// If both an array and non-array are given, the array is never returned
// as comparisons treat arrays as greater than any other value
$val = min('string', array(2, 5, 7), 42);   // string
var_dump($val);

// If one argument is NULL or a boolean, it will be compared against
// other values using the rules FALSE < TRUE and NULL == FALSE regardless of the 
// other types involved
// In the below examples, both -10 and 10 are treated as TRUE in the comparison
$val = min(-10, FALSE, 10); // FALSE
var_dump($val);

$val = min(-10, NULL, 10);  // NULL
var_dump($val);

// 0, on the other hand, is treated as FALSE, so is "lower than" TRUE
$val = min(0, TRUE); // 0
var_dump($val);
