title: How can I prevent Doctrine from thinking a zip code starting with 0 is an octal?
body: <p>I'm working on a symfony project, and I've been through the tutorial but this is my first attempt with a project.  I'm using Doctrine as the ORM, and I have a table of addresses.  Here's part of my schema.yml:</p>
  
  <pre><code>Address:
    connection: doctrine
    tableName: address
    &lt;snip&gt;
    postal_code:
      type: string(10)
      fixed: false
      unsigned: false
      primary: false
      notnull: false
      autoincrement: false
  </code></pre>
  
  <p>And here's an entry from my fixtures.yml file:</p>
  
  <pre><code>Address:
    Addr_1:
      &lt;snip&gt;
      postal_code:  01104
  </code></pre>
  
  <p>The problem is, when I load the data using 'symfony doctrine:data-load', the entry in the database is stored as '580'.  How can I prevent Doctrine from converting the zip code as an octal?</p>
