How to count number of variable parameter in a function – PHP
Sometime while working with function in php, we want to know that how many argument is passing in a function or a variable parameter.
For solving this situation we need to count the variable parameter by this function func_num_args() – it will return the number of argument pass to this function.
Example:-
<?php
function abc(){
echo "Number of argument ".func_num_args();
}
abc(2,5,"a");//Number of argument 3
?>func_get_args — This function returns an array comprising a function’s argument list, it will be used to get the array of arguments.
