关于php的include 给个例子吧 千恩万谢

额 在一个工程(project)里的一个文件夹(db)有一个db_connect.php文件，另一个文件夹(dao)其中有个dao.php,dao.php include("../db/db_connect.php");在project工程里头还有一个usedb文件夹，在usedb文件夹里头还有一个news文件夹，news文件夹里有add.php,而add.php里include("../../dao/dao.php");在运行add.php却找不到db_connect.php

vars.php
PHP code:
<?php

$color = 'green';
$fruit = 'apple';

?>


test.php
PHP code:
<?php

echo "A $color $fruit"; // A

include 'vars.php';

echo "A $color $fruit"; // A green apple

?>




PHP code:
<?php

function foo()
{
global $color;

include 'vars.php';

echo "A $color $fruit";
}

/* vars.php is in the scope of foo() so *
* $fruit is NOT available outside of this *
* scope. $color is because we declared it *
* as global. */

foo(); // A green apple
echo "A $color $fruit"; // A green

?>
