We can easily create functions which can take variable number of arguments in php by using following three functions : func_num_args, func_get_arg and func_get_args. Following code will demonstrate how to do it :
Code:
<?php
function test_func()
{
echo 'No. of arguments passed ', func_num_args();
echo '<br />';
echo 'First argument passed : ', func_get_arg(0), '<br />';
echo 'List of all arguments passed : ';
print_r(func_get_args());
echo '<br /><br />';
}
test_func(1);
test_func(1, 2, 3, 4, 5, 6, 7);
?>
When run the previous code will produce the following output :
Quote:
No. of arguments passed 1
First argument passed : 1
List of all arguments passed : Array ( [0] => 1 )
No. of arguments passed 7
First argument passed : 1
List of all arguments passed : Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 [6] => 7 )
