PHP包含根文件夹中不同子目录的文件

Question

My question is similar to PHP include file strategy needed . I have the following folder structure:

 /root/pages.php /root/articles/pages.php /root/includes/include_files.php /root/img/images.jpg 

All pages in the " /root " and " /root/articles " directories have a "header.php" and "footer.php" file included within them, which are stored within the " /root/includes " directory.

The header and footer pages both contain images stored in the " root/img/ " directory.

As suggested by:

how it`s possible to include a file (include();) from the root folder to a files from different subfolders?

How to use a PHP includes across multiple directories/sub directories with relative paths

I tried the **dirname** solution and the $_SERVER['DOCUMENT_ROOT] solution to include the header and footer in the files stored in the root directory and articles subdirectory.

However, I run into issues when I try and use either method (within the header and footer files) to link images:

<img src=" <?php echo dirname(__FILE__). '/img/image.jpg';?>">

Chrome fails to display the images and throws the following error:

locally: Not allowed to load local resource: file:///C:/root/img/image.jpg

on the server: GET http://host.com/home/public_html/root/img/image.jpg 500 (Internal Server Error)

I have checked the URL's and they appear to be correct. Having googled for solutions, I found that chrome prevents the display of files that contain it's complete file path for security reasons.

How do I get around this? or is there an alternative way to include files (including images) into files stored in any subdirectory?

Answer 1

@sandeep's answer is partially right. because

$_SERVER['DOCUMENT_ROOT'];

will again give back fully qualified path to the root.

<img src=" <?php echo 'http://localhost/favicon.ico';?>"/>

will return image back because now I am not giving it local path as per your problem but url of the server I am running.

Answer 2

for your included scripts try setting the includes_path using set_include_path

set_include_path( $_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . 'includes' . DIRECTORY_SEPARATOR );

Then, to include a script within your pages you can use:

include( 'script.php' );

For the images, prefix the path with a leading slash / ~ ie:

<img src='/img/image1.jpg' />

It tends to be easier to use root relative paths rather than directory relative paths so prefixing with the leading slash means a folder within the root.

Answer 3

This may be help you

$url = $_SERVER['DOCUMENT_ROOT'].'/img/image.jpg';
<img src="<?=$url?>">

Answer 4

Use ../img/image.jpg for including in files inside /root/articles.

Use img/image.jpg for including in files inside /root
