Link()

What is the link() Function?

The link() function is a built-in PHP function that creates a hard link from the target file to the destination file. A hard link is a file system object that associates a name with an inode on the file system.

Here's the basic syntax of the link() function:

link(target, link);

Where target is the name of the file you want to create a hard link to, and link is the name of the hard link you want to create.

How to Use the link() Function?

Using the link() function is straightforward. Here are the steps to follow:

1. Specify the name of the file you want to create a hard link to.
2. Specify the name of the hard link you want to create.
3. Call the link() function, passing in the target file name and hard link name as parameters.

Here's an example code snippet that demonstrates how to use the link() function:

<?php

$target = '/path/to/target/file';
$link = '/path/to/link';
if (link($target, $link)) {
    echo 'Hard link created successfully';
} else {
    echo 'Failed to create hard link';
}

In this example, we use the link() function to create a hard link from the target file /path/to/target/file to the hard link /path/to/link. We then use a conditional statement to print out a message indicating whether the hard link was created successfully or not.

Conclusion

The link() function is a useful tool in PHP for creating hard links between files on a file system. By following the steps outlined in this guide, you can easily use the link() function in your PHP projects to create hard links. We hope this guide has been helpful.
