What are some best practices for ensuring PHP scripts have the necessary permissions to access files via SSH?

To ensure PHP scripts have the necessary permissions to access files via SSH, you can set the appropriate file permissions on the files or directories that need to be accessed. This can be done by using the chmod command in SSH to change the permissions. Make sure that the PHP user (often www-data or apache) has the necessary permissions to read, write, and execute the files.

// Example of setting file permissions in PHP
chmod("/path/to/file.txt", 0644); // Set read and write permissions for owner, read permissions for group and others
