What is Zend Engine?

Pradeep Maurya
  • Zend Engine is used internally by PHP as a compiler and runtime engine. PHP Scripts are loaded into memory and compiled into Zend opcodes.
  • These opcodes are executed and the HTML generated is sent to the client.
  • The Zend Engine provides memory and resource management, and other standard services for the PHP language. Its performance, reliability and extensibility played a significant role in PHP’s increasing popularity.
