title: Generate BIG random number php
body: <p>I want to generate a number with 75 characters using PHP.</p>
  
  <p>I have searched everywhere and got nothing, except for this: <a href="http://dailycoding.com/tools/RandomNumber.aspx" rel="nofollow">http://dailycoding.com/tools/RandomNumber.aspx</a></p>
  
  <p>I do not think it is effective to grab it from that page.</p>
  
  <p>What I have tried is this:</p>
  
  <pre><code>rand(1,9999999999999999999999999999999999999);
  </code></pre>
