How does PHP compare to other languages like Perl or Java in terms of handling persistent data in memory?

When it comes to handling persistent data in memory, PHP is comparable to languages like Perl and Java. PHP provides various mechanisms for storing data in memory, such as using sessions, caching libraries like Memcached or Redis, or storing data in global variables or static properties. Each language has its own set of libraries and tools for managing persistent data in memory, so the choice between them may depend on the specific requirements of the project. 

// Example of storing data in a session in PHP
session_start();
$_SESSION['user_id'] = 123;
$_SESSION['username'] = 'john_doe';
