title: Get the Largest Number in a mySQL Database in PHP
body: <p>I have a SQL Database that has a column like this:</p>
  
  <pre><code>ID
  -----
  0352
  5432
  4382
  3520
  30593
  3992
  295
  </code></pre>
  
  <p>What I want to do is search through that column, find the largest number (30593) and store it in a variable.</p>
  
  <p>This database has other columns, the example above is for demonstration only.</p>
  
  <p>e.g.</p>
  
  <p>$largestNumber = GET LARGEST NUMBER FROM ID</p>
  
  <p>How would I do that in PHP / MySQL</p>
