title: Adding numbers with leading zeros
body: <p>I have a number like <code>00001</code> and I want to keep adding <code>1</code> to it till I reach <code>00044</code></p>
  
  <p>How can I do this in PHP?</p>
  
  <p>I tried but it takes it as <code>1 not 00001</code></p>
  
  <p>So basically what I want is</p>
  
  <pre><code>00001
  00002
  00003
  00004
  00005
  00006
  00007
  
  00008
  00009
  00010
  00011
