警告：require_once（./ mailer / class.phpmailer.php）：无法打开流：

Question

Tree:

--myproject
----mailer
-------class.phpmailer.php
----test
-------index.php
----site.php
----class.php
----db.php
----index.php

index.php: (both)

<?php 
require_once '../site.php';
?>

site.php:

<?php
require_once "class.php";
?>

class.php

<?php
require_once 'db.php';
require_once('./mailer/class.phpmailer.php');
?>

---

When I visit test it shows:

Warning: require_once(./mailer/class.phpmailer.php): failed to open stream: No such file or directory in C:\wamp\www\myproject\class.php on line 3

---

Fatal error: require_once(): Failed opening required './mailer/class.phpmailer.php' (include_path='.;C:\php\pear') in C:\wamp\www\myproject\class.php on line 3

I also tried include_once but same error!

Answer 1

You're calling the

require_once('./mailer/class.phpmailer.php');

From inside index.php, so the file is two levels above.

Change

require_once('./mailer/class.phpmailer.php');

to

require_once('../mailer/class.phpmailer.php');

UPDATE

Just realized you need both index.php files working. It's not the prettiest solution, but you can do it like this:

/test/index.php

<?php

$nested = true;
require_once '../site.php';

?>

/index.php

<?php 

$nested = false;
require_once 'site.php';

?>

This new "nested" variable will determine if the file is inside a directory or on the base.

Edit your class.php to look like this:

<?php

require_once 'db.php';

if ($nested == true)
require_once('../mailer/class.phpmailer.php');

elseif ($nested == false)
require_once('./mailer/class.phpmailer.php');

?>

This should fix the problem in both files.
