Answer / vijaya
The Zend Engine is the internal compiler and runtime engine
used by
PHP4. Developed by Zeev Suraski and Andi Gutmans, the Zend
Engine is an
abbreviation of their names. In the early days of PHP4, it
worked as
follows:
The PHP script was loaded by the Zend Engine and compiled
into Zend
opcode. Opcodes, short for operation codes, are low level binary
instructions. Then the opcode was executed and the HTML
generated sent
to the client. The opcode was flushed from memory after
execution.Today, there are a multitude of products and
techniques to help you
speed up this process.
In the following diagram, we show the how modern
PHP scripts work; all the shaded boxes are optional.
PHP Scripts are loaded into memory and compiled into Zend
opcodes.
