Include error? pls help 1

[Forri]

Hi

I have a php file which has lots of common functions!

The problem is that this file is included in several other PHP script files. Even tough i use the include_once function i still receive an error stating that i'm redeclaring functions!

How can i solve this?

Thanks
Nick

Are you using include_once() and require_once() in all your scripts?

What version of PHP are you running? On my 4.3.6 installation, so long as all scripts and inclusions are using include_once(), I get no errors.

You are likely not using include_once() early enough in your script.

In general, you should be keeping up with the upgrades. There are always bugfixes that might affect your installation. But I can't say for a fact that 4.3.6 fixes any issues with inclusion.

Check on your use of include() versus include_once().

Here's the micro-app I'm testing with:

test_foo.inc:

<?php

function foo ()
{
	print "foo";
}
?>

test_include2.php:

<?php
include_once ('test_include.inc');
?>

test_include1.php:

<?php
include_once ('test_include.inc');
include_once ('test_include2.php');
?>

"test_include1.php" is the entry point. It includes "test_include.inc" then "test_include2.php". "test_include2.php" then also includes "test_include.inc". So "test_include.inc" gets included twice.

So long as I am using include_once(), I get no errors. I can even use include() first then include_once(). But if include_once() is followed by an include(), I get the error.

Plausable...i'm trying everything i can't figure out what it is! do you think if the function extension file is .php should be .inc?

 

[sleipnir214]

With PHP's filesystem functions (which include include[_once]() and require[_once]()), there is no required naming convention.

yeah i know but i taught maybe that if the include is a .php it will run it before including it!! so but doesn't make a diference! the thing is that i use the function_exist and still it gives an error!

Tahnks anyways ...i'll try to figure out on my own cheers!

ps. star for your help!

I had a similar problem in the past.
The solution - although a hack - was to set a declared constant which indicates that the file was already loaded. The include statements were then put with an IF which checks for the constant.
