Let’s dive in and understand how this important feature applies to PHP development!

PHP Create symbolic link

Introduction

A symbolic link is a special file type that points to another file or directory. When a symbolic link is accessed, the system automatically redirects to the target file or directory as if accessing the original file or directory directly. In php, you can use the symlink() function to create symbolic links.

grammar

symlink(string $target, string $link)
Copy after login

in:

  • $target: The path to the target file or directory to be linked.
  • $link: The path of the symbolic link.

Parameter Description

$target Parameters:

  • must be an absolute path.
  • can point to a file or directory.
  • The target file or directory must exist.

$link Parameters:

  • can be an absolute or relative path.
  • The symbolic link must be in a directory with write permission.
  • The file name of the symbolic link can be any name.

return value:

If the operation is successful, the symlink() function returns true; otherwise, it returns false.

Example

Create a symbolic link and link the directory public_<strong class="keylink">html</strong> to the symbolic link www:

symlink("/path/to/public_html", "/path/to/www");

Create a symbolic link and link the file file.txt to the symbolic link myfile.txt:

symlink("/path/to/file.txt", "/path/to/myfile.txt");

Precautions

  • Create an alias for a file or directory.
  • Access the same file or directory in different directories without copying.
  • Move files หรือ directory from one location to another without actually moving them.
  • Create soft links in software deployment.
