How can file permissions affect the installation process of PHP applications like 4image?
File permissions can affect the installation process of PHP applications like 4image by restricting access to necessary files and directories, causing errors during installation. To solve this issue, you can set the appropriate file permissions for the directories and files required by the application. This can be done using the chmod function in PHP to change the permissions of the files and directories to allow the application to read, write, and execute as needed.
// Set file permissions for directories and files
chmod('/path/to/directory', 0755); // set directory permissions to 755
chmod('/path/to/file.php', 0644); // set file permissions to 644
