Java is considered to be a more secure language, compared to PHP. It has more built-in security features while PHP developers have to opt for other frameworks. However, in terms of security, Java works better for complex projects because it can block some features in low-level programming to protect the PC. Java is considered to be more stable than PHP. It requires a longer code which takes time. At the same time, a well-written longer code becomes a more stable application with fewer crashes.
