Is_executable()

What is the is_executable() Function?

The is_executable() function is a built-in PHP function that checks whether a given file is executable. This function returns true if the file is executable and false otherwise.

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

is_executable(file);

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

How to Use the is_executable() Function?

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

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

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

<?php

$file = '/path/to/file';
if (is_executable($file)) {
    echo 'The file is executable';
} else {
    echo 'The file is not executable';
}

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