max Find highest value &reftitle.description; mixedmax mixedvalue mixedvalues Alternative signature (not supported with named arguments): mixedmax arrayvalue_array 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. Values of different types will be compared using the standard comparison rules. For instance, a non-numeric string will be compared to an int as though it were 0, but multiple non-numeric string values will be compared alphanumerically. The actual value returned will be of the original type with no conversion applied. Be careful when passing arguments of different types because max can produce unpredictable results. &reftitle.parameters; value Any comparable value. values Any comparable values. value_array An array containing the values. &reftitle.returnvalues; max returns the parameter value considered "highest" 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. If an empty array is passed, then &false; will be returned and an E_WARNING error will be emitted. &reftitle.examples; 4 $val = max(array(2, 4, 8), array(2, 5, 1)); // array(2, 5, 1) // If both an array and non-array are given, the array will be returned // as comparisons treat arrays as greater than any other value $val = max('string', array(2, 5, 7), 42); // array(2, 5, 7) // 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 example, -10 is treated as TRUE in the comparison $val = max(-10, FALSE); // -10 // 0, on the other hand, is treated as FALSE, so is "lower than" TRUE $val = max(0, TRUE); // TRUE ?> ]]> &reftitle.seealso; min count
