MIN is an advanced unit/integration test frameworkfor Maemo/Linux. It supports test cases written inC (or C++) as well as scripted test cases with (atailor made) MIN scripter, Lua, or Python. Testcases are compiled into test modules that areloaded dynamically. A test case is executed in aseparate process.License: GNU General Public License v2Changes:|

MIN(3) 1 MIN(3) min - Find lowest value SYNOPSIS
mixed min (array $values) DESCRIPTION
mixed min (mixed $value1, mixed $value2, [mixed $...]) If the first and only parameter is an array, min(3) returns the lowest value in that array. If at least two parameters are provided, min(3) returns the smallest of these values. Note Values of different types will be compared using the standard comparison rules. For instance, a non-numeric string will be com- pared to an integer as though it were 0, but multiple string values will be compared alphanumerically. The actual value returned will be of the original type with no conversion applied. PARAMETERS
o $values - An array containing the values. o $value1 - Any comparable value. o $value2 - Any comparable value. o $... - Any comparable value. RETURN VALUES
min(3) returns the parameter value considered "lowest" according to standard comparisons. If multiple values of different types evaluate as equal (e.g. 0 and 'abc') the first provided to the function will be returned. EXAMPLES
Example #1 Example uses of min(3) <?php echo min(2, 3, 1, 6, 7); // 1 echo min(array(2, 4, 5)); // 2 // 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 rule FALSE < TRUE 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 ?> SEE ALSO
