How do I generate a random number between 1-10 in PHP?Example 1, use the shuffle function to generate a random number.$arr =range (1,10);Shuffle ($arr);foreach ($arr as $values){echo $values. " ";}?>Example 2, use the Array_unique function to

This example does not introduce any new knowledge. It only refers to the display of 256 characters per page on the screen. The "Left" and "right" arrow keys are used to flip the page. The code for drawing each page is as follows: [Java]Private void
