PHP Bug Type: Documentation problem
Bug description: "Function arguments", section "Variable-length argument
lists": give examples
Description:
------------
Please include examples on how to define (and call) functions with a
variable number of arguments:
Example 17.11. Define a function with variable number of arguments:
function test() {
echo func_get_arg(0);
}
test('hello'); // prints 'hello'
Example 17.12. Other method to define a function with optional second
argument
function test($foo, $bar=null) {
echo $bar;
}
test('one','two'); // prints 'two'
test('one'); // prints nothing
Example 17.13. Wrong way to define a function with optional second
argument
function test($foo, $bar) {
...
}
test('one'); // gives warning, that argument 2 is missing for test()
Why am I asking for this?
Because the current explanation "No special syntax is required" is not
very descriptive. So my first guess was the wrong way shown in Example
17.13
