Including functions, scope.

3 New Member

Hi everyone, I'll try to be brief and to the point - i'm starting to incorporate include() into my php pages to clean up the code but seem to run into problems when trying to call functions that are included in different files. I've been trying to do some research on function scope and please excuse my ignorance, but is this at all possible? For example we have two files:

File 1: function.inc

<?php function test() {

switch ( $var ) {
case ( $var < 130 ):
echo " A " ;
break;
case ( $var < 480 ):
echo " B ";
break;
case ( $var < 1230 ):
echo " C ";
break;
case ( $var < 1830 ):
echo " D ";
break;
case ( $var < 1831 ):
echo " E ";
break;
}
}
?>

And to clean up another page, in another file, index.php - I'd like to be able to call the function test() ...

File 2: index.php

<head>
<title>Testing Page</title>

<?php include 'function.inc'; ?>

</head>

<body>

<?php test(); ?>

</body>
</html>

Could anyone please help me? And if this isn't possible, is there any kind of workaround for these kinds of things? Thanks in advance.

This is possible and For your test function you have o pass function parameters also.

for a example. we will get your func.inc file

[PHP]<?php
function test($var)
{

switch ( $var ) {
case ( $var < 130 ):
echo " A " ;
break;
case ( $var < 480 ):
echo " B ";
break;
case ( $var < 1230 ):
echo " C ";
break;
case ( $var < 1830 ):
echo " D ";
break;
case ( $var < 1831 ):
echo " E ";
break;
}
}
?>[/PHP]

then from your calling script use like this.

[PHP]<?php
include 'func.inc';
$var = 500; //change the value here and call for the script
test($var);
?>[/PHP]

Hi,

An alternative (and IMO better) method to achieve what you are looking for would be to put this and any other standard functions within a class - this will provide much more flexibility around how you use, reuse and maintain the functions included within the class.. there are a number of tutorials around the net if you are not familiar with the concept.. You could take a look at http://www.php-editors.com/articles/...hp_classes.php to start you off.

I've gotten the functions to work with parameters, now is there any way to perform this same idea with remote functions without parameters? Thanks again for everyone's help.

You can define global variables that can be used in any part of you code.

This can be done like this:
[PHP]
// Create a test function
// this could be included from another file
function testFunc()
{
echo $GLOBALS['MyVar'];
}

// Define a global variable
$GLOBALS['MyVar'] = "I am a global vairable!";

// Call the test function
testFunc();

// This will output: I am a global variable
[/PHP]
