Run Function Via URL

[N402KC]

Howdy Yall,

 

Ive spent $200 on these damn PHP books and none of em tell me how to run functions. Only how to write the sons of code. Can yall help me in trying to figure out how i can do this. Here is what i wanna do;

 

For Example;

 

function hello()
{
      echo "Hello World";
}

 

That code is in a page called acars.php. Now when the user loads the page acars.php, nothing happens, but when they go to the url in this format. http://mydomain.com/acars.php/hello , Then it will echo Hello World.

 

Let me know what I can do and how I can do it please. Im startin to loose my patience lol. Thanks all.

All that block of code does is define the function and how it operates on data. To run the function you can do:

 

<?php
function hello() {
  echo "Hello World";
}

hello();
?>

I know how to run the function via code. But I want the function to code via the URL. So once the user goes to http://mydomain.com/acars.php/hello , It will run the function and display Hello World

O i gotcha - first post was a lil unclear

 

You would have the a link like:

<a href="./blah.php?run=hello">Say Hello</a>

 

Then when someone clicks it you need to check the array $_GET for the 'run' array key.

 

if(isset($_GET['run']) && $_GET['run'] == 'hello') {
  hello();
}

 

Read up on how to use $_GET, $_POST and html forms ..etc.

Yeah im aware of it. I really wanted to see if there was a easier way. I did use that way but it was a pain. Thanks,

Are you serious?

 

If you want to have "file.php/hello" You'll need to use mod_rewrite which will require the $_GET anyway.

Agreed with oni-kun the easiest way is to use  ddubs solution.
