In the above case structure, if the user doesnt give any value (simply press enter) then, it should also accept.
How it can be done ?
With Regards

Hello Groups
I am trying to find out ways of comparing a value from a 'c' structure to a value in another 'C' structure. the 'C' structure can be a List or liked list as it contains lot many records.
if we loop it in both the structures it is going to consume time.

Hello Experts,
I was wondering how can we get a fall trough case structure.
Eg: If we have two cases A and B and a default; if I do not break after A, it should execute all the statements of A as well as B if I break after B else fall through even lower.
I tried this:

min
MIN(3) 1 MIN(3)min - Find lowest valueSYNOPSIS
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
