Under Linux, you can use the Crontab + PHP tutorial approach: 1. Use Crontab–e to edit timed tasks Content is: XX:XX:XX executes a test.php file 2, the PHP file must be in the first line of the file, plus the interpreter path (as Perl did) #!/usr/local/bin/php The execution of PHP requires Apache support, the execution of the shell script requires Linux support, and Linux supports the ability to run a program on a regular basis. ---------------

PHP Tutorial SQL Prevention injection and attack technology implementation and methods1. The MAGIC_QUOTES_GPC option in the PHP configuration file php.ini is not turned on and is set to off 2. Developers do not check and escape data types But in fact, the 2nd is the most important. I think that it is the most basic quality of a web programmer to check the data type entered by the user and submit the correct data type to the MySQL tutorial. But in reality, many small white web developers often

are two ways to implement data sharing between these runnable objects:1, encapsulate the shared data in another object, and then pass the object to each Runnable object. The way each thread operates on shared data is also assigned to that object, which makes it easy to implement mutexes and communications for each operation on that data.2, these runnable objects as the internal classes in a class, the sharing of data as the member variables in this
