php Function

[pragan]

Hi,

I have a function in my script and this will take the parameter from the url to give an output. The output has almost 10 variables($age, $name....). I want to use this function in my other files(php) but I do not want to print all the output(10). Depending on the page I am I want to display 2 out 10 or 3 out of 10 variables. I am sure its possible but not sure how to get it.

For example,
<?php
Function show_data($id) {

$link = "http://abc.com?id=$_GET['id']";

//I will do fopen($link,r) and then get the data stored from the link.
//After doing some text manipulation like adding uppercase, removing "" etc I will have the output stored as
$name= $data[0];
$age= $data[2];
//etc..
//then close the function
?>

So I want to use this function to just display the required output based on the place/page where I want to, something like this :
//Call the above function and then just show age in file_one.php
//Call the above function and then just show name in file_two.php


Please help me out and let me know if I am clear in explaining this.

thanks
pragan.

In the future please use [code] or [php] tags to make your post easier to read.

This should help:

<?php

function showData()
{
    $args = func_get_args();

    $id = array_shift($args);

    $name = 'Joe Blow';
    $age  = 21;
    $foo  = 'bazbazbaz';

    foreach ($args as $arg) {
        echo ${$arg} . "\n";
    }
}

/**
 * Output:
 * Joe Blow
 * 21
 */
showData('SomeId', 'name', 'age'); 

/**
 * Output:
 * Joe Blow
 * bazbazbaz 
 */
showData('SomeId', 'name', 'foo');

/**
 * Output:
 * 21
 * Joe Blow
 * bazbazbaz 
 * bazbazbaz 
 */
showData('SomeId', 'age', 'name', 'foo', 'foo');
