You may have noticed that, in all the examples we have given you so far, we have given you two pages-a simple HTML page with a form, and another php (as the mainstream development language) script used to process form input and generate corresponding output. However, php (as the mainstream development language) provides a elegant way to combine the two pages with the $ submit variable.
As you know, once a form is submitted to php (as the current mainstream development language) scripts, all form variables become php (as the current mainstream development language) variables. Now, in addition to user-defined variables, a variable named $ SUBMIT is created each time you click "submit" in the form. Therefore, by testing whether the variable exists, a smart programmer can use only one page to initialize the form and generate the submitted output.
Let's demonstrate to you-we use a page to implement the above lucky cookies example, including the initial date selection page and the lucky Cookies page below. Let's assume that the new php (as the mainstream development language) file is also called "cookie. php (as the mainstream development language )"

If (! $ Submit)

// If $ submit does not exist, it indicates that the form has not been submitted.
