PHP Script Life cycle
The PHP script life cycle refers to the sequence of events that occur when a PHP script is executed. The life cycle consists of several stages, including parsing, compilation, execution, and cleanup.
During the parsing stage, the PHP engine reads and interprets the script’s source code, identifying the various components of the code such as variables, functions, and classes.
In the compilation stage, the PHP engine converts the parsed code into a set of machine instructions that can be executed by the computer’s processor.
The execution stage is when the compiled code is actually run, with the PHP engine executing the instructions in the correct sequence to produce the desired output.
Finally, in the cleanup stage, any resources used during the script’s execution are released and any temporary files or variables are deleted. Overall, the PHP script life cycle is a complex process that involves multiple stages, but it is necessary for creating dynamic and interactive web applications.
