Is_link()

What is the is_link() Function?

The is_link() function is a built-in PHP function that checks whether a given path is a symbolic link. This function returns true if the path is a symbolic link, and false otherwise.

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

is_link(file);

Where file is the path to the file you want to check.

How to Use the is_link() Function?

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

1. Specify the path to the file you want to check.
2. Call the is_link() function, passing in the file path as a parameter.
3. Use the resulting boolean value to determine whether the path is a symbolic link.

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

<?php

$file = '/path/to/symlink';
if (is_link($file)) {
    echo 'The path is a symbolic link';
} else {
    echo 'The path is not a symbolic link';
}

In this example, we use the is_link() function to check whether the path /path/to/symlink is a symbolic link. We then use a conditional statement to print out a message indicating whether the path is a symbolic link or not.
