如何生成1到100万之间的随机数？

Question

I want to make a function the generates a random number from 1 to million .. and put it in a form of

"You have won [ random value ] points. Congratulations."

and somehow save it into variable "x" that i can call in a text box so in the text box value which like:

<input class="textbox1" type="text" readonly value="[X]"> 
<p> [X] </p>
<a href="mywebsite" data-text="[X]"></a>

So i can use it in different places, how could I do it ?

Answer 1

Generate random number between 1 and 1 million and save in $randnumber; Then echo the sentence. Finally, show that number in HTML by inserting PHP code:

//...
$randnumber = rand(1, 1000000);

echo "You have won ".$randnumber." points. Congratulations.";
?>

<input class="textbox1" type="text" value="<?= $randnumber ?>" readonly> 
<p> <?= $randnumber ?> </p>
<a href="mywebsite" data-text="<?= $randnumber ?>">Text</a>

I think there are no syntax errors.

Answer 2

In Javascript you can use:

Math.floor((Math.random() * 1000000) + 1);

This will generate a number between 1 and 1 million.

A snippet to test:

 console.log(Math.floor((Math.random() * 1000000) + 1)); 

Answer 3

使用php函数rand（）

rand(1, 1000000);

Use this if want better random numbers:
