The user's data is held against a unique session ID. These IDs are sent to the browser via session cookies, and the ID is used to recover session data. Cookies, unlike sessions, are used as a means to store data in the end-user's browser to track the end-user. The actual data from sessions are not stored on the browser. Instead, it is stored in the user's session record on the server. What are the various types of errors in PHP? Notice errors Warning errors usually don't stop the execution of the script. It occurs when the user attempts to access an undefined variable. Parse errors (Syntax error) Parse errors occur as a result of a syntax error. This error interrupts the execution of the script. It can occur due to many reasons in PHP. Commonly – Open quotes Missing semicolon Open braces Missing or extra parentheses Fatal errors – This error usually occurs when you try to access an undefined function. It creates a situation where PHP knows what you have written but can't do it. It stops the execution of the entire script. Warning errors – These are similar to notice errors. Like notice errors, it does not stop the execution of the script. It occurs due to missing files and incorrect parameters in a function. Differentiate between include, require, include once, and require once ()? If a required file is missing, a fatal error occurs on PHP but only emits a warning in case of include. Include () shows an alert if it cannot have a file. The rest of the script runs – include once, require once. Differentiate between unset () and unlink (). Unlink is a file system handling function in PHP. It is used to delete files. If you want to delete a file from coding, you can use the unlink () function to delete it. In contrast, unset () is a variable management function used to undefined a variable. Explain constructor and destructor in PHP. Constructor is a unique PHP function that turns on automatically whenever there is a formation of an object from a class. On the other hand, destructor is another particular PHP function that is automatically called if the object is deleted or goes out of scope.
