PHP min() Function: Finding the Minimum Value
This article explains how PHP's min() function determines the smallest value, detailing its behavior with single array arguments versus multiple scalar arguments, describing parameters and return values, and providing clear code examples for common use cases.
The min() function in PHP returns the smallest value among its arguments. When a single array is passed, it returns the minimum element of that array; with multiple arguments, it compares them and returns the smallest.
Parameters
mixed $values – an array of values, or multiple comparable values ( $value1 , $value2 , ...).
Return value
Returns the lowest value among the provided arguments. If arrays are compared, they are considered larger than scalar values.
Examples
When mixing arrays and scalars, arrays are treated as larger, so the function returns the scalar minimum.
