5. Payment Hot Issues

In PHP mall payment development, common payment hot issues include:

1. Payment amount error: It may be due to an error in the conversion algorithm, Caused by problems such as incorrect server time zone setting.

2. Payment timeout: User payment times out due to network transmission or other reasons.
