What is the significance of setting file permissions in PHP when uploading files to a server?

Setting file permissions in PHP when uploading files to a server is significant because it allows you to control who can access, read, write, and execute the uploaded files. This helps to ensure the security of your server and prevent unauthorized users from tampering with sensitive files. By setting appropriate file permissions, you can restrict access to certain files or directories, making your application more secure. 

// Set file permissions for uploaded files
$uploadDir = 'uploads/';
$uploadedFile = $uploadDir . basename($_FILES['file']['name']);

// Set file permissions (e.g., 0644 for read/write by owner, read by group, and read by others)
chmod($uploadedFile, 0644);
