Running a function from with another function

[Darkmatter5]

Say I had a page of functions that I call within various pages to generate various aspects of the pages.  Now say I have a function within that functions page that needs to call another function.  How do I go about calling a function from within another function?

 

 

Example:

function hi() {
    echo "Hi!"
}

function hello() {
    echo "Hello!" (and also the output of hi());
}

 

How do I get hello() to have the following output?

"Hello! Hi!"

 

Thanks!

use return not echo in the hi function.

just call the other function in it

 

<?php
function hi() {
    $ret = "Hi!";
    return $ret;
}

function hello() {
    $ret = "Hello! ";
    $ret .= hi();
    return $ret;
}

echo hello();
?>

Or to remove a bit of redundancy

 

<?php
function hi() {
    return "Hi!";
}

function hello() {
    return "Hello! " . hi();
}

echo hello();
?>

These are called multidimensional functions correct?

AFAIK there's no special term for calling a function from inside another function.  AFAIK the only "multidimensional" anything out there is multidimensional arrays.

No, it's simply calling a function in a function. You do it all the time, just with our examples, both functions are user defined.

 

You're thinking arrays, where an array within an array creates a multidimensional array
