How does the Zend Engine optimize PHP code for faster execution and what tools can be used for this purpose?

The Zend Engine optimizes PHP code for faster execution by using techniques such as opcode caching, just-in-time compilation, and memory management. Tools such as OPcache, Xdebug, and Blackfire can be used to analyze and optimize PHP code for better performance. 

// Example code snippet using OPcache for opcode caching
if (!extension_loaded('Zend OPcache')) {
    echo 'OPcache is not available';
} else {
    echo 'OPcache is enabled';
}
