What is the significance of Thread Safety in PHP and how does it affect code execution?

Thread safety in PHP refers to the ability of a piece of code to be executed safely in a multi-threaded environment without causing unexpected behavior or data corruption. This is important because PHP is not inherently thread-safe, so developers must take precautions to ensure their code can be safely executed in a multi-threaded environment. One way to achieve thread safety in PHP is by using synchronization mechanisms such as locks or mutexes to control access to shared resources. 

$lock = new Mutex();

$lock->lock();

// Critical section - code that needs to be thread-safe

$lock->unlock();
