Which of the following php functions accept any number of parameters

Join The Discussion

In PHP there are functions like unset[] that support any number of parameter we throw at them.

I want to create a similar function that is capable of accepting any number of parameters and process them all.

Any idea, how to do this?

In PHP, use the function func_get_args to get all passed arguments.

An alternative is to pass an array of variables to your function, so you don't have to work with things like $arg[2]; and instead can use $args['myvar']; or rewmember what order things are passed in. It is also infinitely expandable which means you can add new variables later without having to change what you've already coded.

You can use these functions from within your function scope:

• func_get_arg[]
• func_get_args[]
• func_num_args[]

Some examples:

foreach [func_get_args[] as $arg]
{
    // ...
}

for [$i = 0, $total = func_num_args[]; $i < $total; $i++]
{
    $arg = func_get_arg[$i];
}

You will have 3 functions at your disposal to work with this. Have the function declaration like:

function foo[]
{
    /* Code here */
}

Functions you can use are as follows

func_num_args[] Which returns the amount of arguments that have been passed to the array

func_get_arg[$index] Which returns the value of the argument at the specified index

func_get_args[] Which returns an array of arguments provided.

You can use func_get_args[] inside your function to parse any number of passed parameters.

If you are using PHP 5.6 or later version, argument lists may include the ... token to denote that the function accepts a variable number of arguments. The arguments will be passed into the given variable as an array; Simply Using ... you can access unlimited variable arguments.

for example:
