func_num_args() :- Returns the number of arguments passed to the function

This function is used when we need to return number of arguments passed by function.

<?php
function my_function() {
$no_of_args = func_num_args();
echo “Number of arguments passed to this function”.$no_of_args;
}
my_function(‘arg1′,’arg2′,’arg3′,’arg4’);
?>

Output :-

Number of arguments passed to this function 4
