title: PHP remove first zeros
body: <p><strong>Want to remove all <code>0</code> placed at the beginning of some variable.</strong></p>
  
  <p>Some options:</p>
  
  <ol>
  <li>if <code>$var = 0002</code>, we should strip first <code>000</code> (<code>$var = 2</code>)</li>
  <li>if <code>var = 0203410</code> we should remove first <code>0</code> (<code>$var = 203410</code>)</li>
  <li>if <code>var = 20000</code> - do nothing (<code>$var = 20000</code>)</li>
  </ol>
  
  <p><strong>What is the solution?</strong></p>
