What are some tips for troubleshooting and resolving issues with input values being truncated in PHP forms?

Issue: Input values in PHP forms are being truncated due to a limit on the maximum input size set in the php.ini file. To resolve this issue, you can increase the value of the `post_max_size` directive in the php.ini file to allow larger input values to be processed.

// Increase the maximum post size in php.ini file
post_max_size = 20M
