// The string 'hello' when compared to an int is treated as 0

// Since the two values are equal, the order they are provided determines the result

echo min ( 0 , 'hello' ); // 0

echo min ( 'hello' , 0 ); // hello



// Here we are comparing -1 < 0, so -1 is the lowest value

echo min ( 'hello' , - 1 ); // -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)



// 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)



// 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



// 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

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



// 0, on the other hand, is treated as FALSE, so is "lower than" TRUE

$val = min ( 0 , TRUE ); // 0
