How can PHP scripts be used to set CHMOD permissions for folders and files?

To set CHMOD permissions for folders and files using PHP scripts, you can use the `chmod()` function. This function takes two arguments: the file or directory path and the permissions you want to set. You can use octal notation to specify the permissions, such as 0755 for read, write, and execute permissions for the owner, and read and execute permissions for others.

// Set CHMOD permissions for a folder
$folderPath = '/path/to/folder';
$permissions = 0755;
chmod($folderPath, $permissions);

// Set CHMOD permissions for a file
$filePath = '/path/to/file.txt';
$permissions = 0644;
chmod($filePath, $permissions);
