how to include library files in php program

[chandran27]

hi friends

The line below is in my php program:
include 'opendb.php';

But it gives the following error:

PHP Warning: include(opendb.php) [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory in C:/...

No such files are present in the php installation. please tell me if any one has the solution for this.

Make sure the path of the included file is correct.
Make sure the file exists.

For more info pleae read here [gr.php.net]

The function include, require etc. open files relatively to the file opened by the browser:

let's say you have such a dir/file structure:
include/head.php
include/functions.php
index.php

index.php:

<?php
include 'include/head.php';
?>

head.php:

<?php
//include 'functions.php' //will return error
include 'include/functions.php';
?>

Hope this cleares everything
