  1. POPHP controlling the output of rand
    text
    copied!<p>Is it possible to control the output of rand, for example if I just want rand to give me the output of the variable $roll1 with the value or number of 1 half the time out of the six possibilities when rand is ran or when the browser is refreshed, how does one accomplish that?</p> <p>My code sucks but I am fighting to learn, I only get one every now and then, but it's not consistent, I want a 1 every time I refresh the page.</p> <p>So If I refresh the page 6 times I should get a 1 out of the variable $roll1 three times, and the rest of the values for $roll1 should be random.</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html;charset=utf-8"/&gt; &lt;title&gt;loaded dice&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;h1&gt;loaded dice&lt;/h1&gt; &lt;h3&gt;loaded dice&lt;/h3&gt; &lt;?php // loaded dice, should roll the number 1 half the time out of a total of 6. // So if I refreshed my browser six times I should at least see three 1's for roll1. $roll1 = rand(1, 6); // Okay is it possible to divide rand by two or somehow set it up // so that I get the the value 1 half the time? // I am trying division here on the if clause in the hopes that I can just have // 1 half the time, but it's not working,maybe some type of switch might work? :-(. if ($roll1 == 3) { $roll1 / 3; } if ($roll1 == 6) { $roll1 / 6; } if ($roll1 == 1) { $roll1 / 1; } // This parts works fine :-). // Normal random roll, is okay. $roll2 = rand(1, 6); print &lt;&lt;&lt;HERE &lt;p&gt;Rolls normal roll:&lt;/p&gt; You rolled a $roll2. &lt;p&gt;Rolls the number 1 half the time:&lt;/p&gt; &lt;p&gt;You rolled a $roll1.&lt;/p&gt; HERE; // Notice how we used $roll1 and 2, alongside the HERE doc to echo out a given value. ?&gt; &lt;p&gt; Please refresh this page in the browser to roll another die. &lt;/p&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>
