I have an array of colors having dynamic values which depends on database. now these values are required in a function which takes values only like this function('para1','para2','para3','para4') where param1 to param4 are color values in an array. Problem is how can i parse these values to that function in the above stated format.Only a programminng logic required.Language is php.
Suppose dynamic array is color[]=('red','maroon','blue','green'); and these value should be passed to this function like :setLineColor('red','maroon','blue','green');
I m using this function for creating graphs.(Lib using PHP_graphlib: link: http://www.ebrueggeman.com/phpgraphlib/documentation.php) Any other suggested library is welcomed.Plz provide a simple example with it.

To pass an entire array to a function, only the name of the array is passed as an argument. result = calculateSum(num); However, notice the use of [] in the function definition. This informs the compiler that you are passing a one-dimensional array to the function.
A whole array cannot be passed as an argument to a function in C++. You can, however, pass a pointer to an array without an index by specifying the array's name. In C, when we pass an array to a function say fun(), it is always treated as a pointer by fun().
Arrays can be passed as arguments to method parameters. Because arrays are reference types, the method can change the value of the elements.
Since PHP 5.6 you can use argument unpacking with the triple-dot-operator:
setLineColor(...$colors);
You can use the function call_user_func_array.
<?php
$colors = array('red','maroon','blue','green');
call_user_func_array('setLineColor', $colors);
?>
If you want to call the method of an object, you can use this instead:
<?php
$graph = new ...
$colors = array('red','maroon','blue','green');
call_user_func_array(array($graph, 'setLineColor'), $colors);
?>
