I read a book about PHP a few days ago, which impressed me deeply. I will first introduce the development history of PHP, and then teach you a little trick on uploading multiple files using PHP. Let us first briefly introduce PHP! PHP was originally created by Rasmus Lerdorf in 1994. It started as a simple program written in Perl language to count visitors to his own website. Later it was rewritten in C language, including access to the database.

In the future, more and more websites are using PHP, and there is a strong demand to add some features, such as loop statements and array variables, etc., when new members join After the development process, in mid-1995, PHP 2.0 was released. The second version is named PHP/FI (Form Interpreter). PHP/FI added support for mSQL, and has since established PHP's position in dynamic web development. By the end of 1996, there were 15,000 websites using PHP/FI; by mid-1997, the number of websites using PHP/FI exceeded 50,000. In mid-1997, the development plan for the third version was started. The development team joined Zeev Suraski and Andi Gutmans, and the third version was named PHP3. In 2000, PHP4.0 came out again, which added many new features. characteristic. The following will introduce you to a method of uploading multiple files in PHP.

PHP code implementation for uploading multiple files:
