PHP Programing language

While discussing passing arguments to functions, it's worth nothing that you can set up functions so that they can take a variable number of arguments. In other words, say you have a function named connector, which connects words into a text string. you could call it like this:

Connector ("Hello");

or like this:

Connector (""Hello","there","again");

func_num_args- Returns the number of arguments passed
func_get_arg -Returns a single argument
func_get_args -Returns all arguments in an array

If you want to start the connector function

function connector ()
{
$ arguments = func_get_args();
}

Then you can loop over the arguments like this:

Note that you can get the number of arguments from the func_num_args function:

function connector ()
{
$data="";
$ arguments = func_get_args();
for ($loop_index=0; $loop_index <func_num_args();$loop_index++)
{
data=$arguments [$loop_index]." ";
}
echo $data;
}

Program:

<html>
<head>
<title>Passing variable arguments to Function  </title>
<body>
<h1>Passing variable arguments to Function </h1>
<?php
echo "Passing 'How' 'are' 'things?' to connector...<br>";
echo "Getting this result:";
connector ("How","are","things?");
function connector()
{
$data = "";
$arguments = func_get_args();
for ($loop_index=0; $loop_index <func_num_args();
$loop_index++)
{
$data .= $arguments [$loop_index]." ";
}
echo $data;
}
?>
</body>
</html>
