vars in functions

[Anon]

Hi everyone,

i have a pretty simple q for you. I have 2 functions. In the first one there is a var named "status" and in the second function i want to use it. But if i echo the value of the var in the second function there is no value anymore. I thought i have to make them global ut even that did not work (i think i got the use of global vars wrong)

Code:

<?
global $var;

function test(){
$var = "Hello World";
}

function sayhi(){
echo "Hello, var has $var as its value.";
}

test();
sayhi();
?>

i know that i could call the second function from the first one and give a parameter to the secondbut that is not what i want. The thing i want to achive is much more complex than this little example.

thanks for any help

regards ali

I think that you need to use global $var; inside the function definition, not outside of it.

<?php

$var = '';

function test(){
global $var;
$var = "Hello World";
}

function sayhi(){
global $var;
echo "Hello, var has $var as its value.";
}

test();
sayhi();
?>

But it is a shocking fudge and very unreadable. Poor software engineering.

i know its not good software engeneering but thanks that you gave me a possible soloution. If you know a better one feel free to share that idea with me. I just begun programming and so i know i am not a guru and defininetly not a good software-emgeneer.
