Using PHP rename() Function to Rename Files and Directories

In PHP, the rename() function is used to rename files or directories by specifying the source name and the target name.

Syntax: bool rename ( string $source , string $target ) Parameters: $source: the name of the source file or directory (required). $target: the name of the destination file or directory (required).

Return value: Returns TRUE on success and FALSE on failure.

Examples:

Renaming a file:

<?php
$old_name = "old_file.txt";
$new_name = "new_file.txt";

if (rename($old_name, $new_name)) {
    echo "File renamed successfully!";
} else {
    echo "File rename failed!";
}
?>

Renaming a directory:

<?php
$old_name = "old_directory";
$new_name = "new_directory";

if (rename($old_name, $new_name)) {
    echo "Directory renamed successfully!";
} else {
    echo "Directory rename failed!";
}
?>

Notes: The function may be limited by filesystem permissions; ensure you have sufficient rights. If the source does not exist, rename() returns FALSE.

Summary: The rename() function provides a simple way to change the name of files or directories in PHP, and the examples demonstrate its basic usage.
