PHP include statements and require statements

<?  / *    PHP include statement and require statement        include and require statements are the same except for        error handling:            *require Generates a fatal error and stops the script        *include only generates a warning, and the script continues                Therefore, if you want to continue execution and output the results to the user        , use include if the containing file is missing. Otherwise        , in mining, CMS, or complex PHP application programming, always        use require to perform stream referencing of critical files. This helps to improve        the security and integrity of your application, and it saves you a                lot of effort to include files if you lose them outside of a critical file. This means that you can        create a standard header, footer, or menu file for all pages. Then, when the page header needs to be updated        , you only need to update the page header contains the file            syntax:                include ' filename ';                Require ' filename ';     */?>
