I am getting the following error while running the code,
运行代码时出现以下错误，
Warning: require_once(product.php) [function.require-once]: failed to open stream: No such file or directory in C:\xampp\htdocs\pro\application\modules\products\controllers\test1.php on line 2
Fatal error: require_once() [function.require]: Failed opening required 'product.php' (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\pro\application\modules\products\controllers\test1.php on line 2
警告：require_once(product.php) [function.require-once]：无法打开流：第 2 行的 C:\xampp\htdocs\pro\application\modules\products\controllers\test1.php 中没有这样的文件或目录
致命错误：require_once() [function.require]：在 C:\xampp\htdocs\pro\application\modules\ 中打开所需的“product.php”（include_path='.;C:\xampp\php\PEAR'）失败第 2 行的产品\控制器\test1.php
The code is simple,
代码很简单，
<?php
require_once "product.php";
$array = "I am Fahad and I am testing this code";
$start = 4;
$limit = 9;
$value = limit($array, $start, $limit);
echo $value;
?>
The file product.phplies in the same directory as of the file which I am running. It still is giving an error. Please help out. Thanks

The actual current directory is not alwaysthe same than the script you are running, especially inside a frameworklike you seem to use right now.
实际的当前目录并不总是与您正在运行的脚本相同，尤其是在您现在似乎正在使用的框架中。
To make sure this is working, use
要确保这是有效的，请使用
require_once dirname(__FILE__) . '/product.php';
require_once dirname(__FILE__) . '/product.php';
on 5.3, you can even say :
在 5.3 上，你甚至可以说：
require_once __DIR__ . '/product.php';
require_once __DIR__ . '/product.php';
Hope this helps !
希望这可以帮助 ！

Check your filenames, especially case sensitivity (product.php != Product.php).
检查您的文件名，尤其是区分大小写（product.php != Product.php）。

The error is simple, it can't find the file "product.php" in the place its currently looking.
错误很简单，它在当前查找的位置找不到文件“product.php”。
Personally I would never trust the script to know where to look automatically, I would always try and give absolute paths. For example:
就我个人而言，我永远不会相信脚本会自动知道在哪里查看，我总是会尝试给出绝对路径。例如：
require_once $_SERVER['DOCUMENT_ROOT'] . '/somedir/anotherdir/product.php';
