include_path doesn't recurse?

Question

I have several separate websites that live in separate directories. For includes that they have in common, I have it living in the root directory where the rest of them live.

user@hostname:/var/www$ ls
website_1 website_2 website_3 common_files 

I want to include a Zend package, so I have my include path

ini_set("include_path", get_include_path() . ":/var/www/common_files/Zend");
require_once("Mail.php");

Mail.php loads okay, but then somewhere in there is this line

require_once 'Zend/Mail/Transport/Abstract.php';

which gives this error

Warning: require_once(Zend/Mail/Transport/Abstract.php): failed to open stream: No such file or directory in var/www/common_files/Zend/Mail.php on line 26

So php doesn't recursively descend into the directory structure of the include paths. Do I have to move Zend into each website direcory, spell out the path to every include, or what?

---

BTW Abstract does exist:

user@host:/var/www/common_files/Zend$ tree -d 
...
`-- Mail/Transport
    |-- Mail/Transport/Abstract.php
    |-- Mail/Transport/Exception.php
    |-- Mail/Transport/Sendmail.php
    `-- Mail/Transport/Smtp.php

9 directories, 32 files

Answer 1

EDIT: You want to change your include_path to include /var/www/common_files

What, if anything, is still broken after you do this?

Answer 2

Stupid answer: Does Abstract.php exist?

require_once 'Mail/Transport/Abstract.php';

Try this, because Mail.php iz already in Zend folder, I guess it looks for /Zend/Zend/.../Abstract.php

Answer 3

It looks like Zendis the working directory here, so your statement is looking for /Zend/Zend/Mail/Transport/Abstract.php. Try just cutting off Zend from the statement and it should work fine.

Answer 4

you need to set your include path to the path where the Zend folder is. then you include the files like so

require_once 'Zend/Mail.php'
