title: How many interfaces can a class implement in PHP?
body: <p>I'm looking for an answer to question which is not difficult, but I can't find out how many interfaces can be implemented by one class.</p>
  
  <p>Is this possible?</p>
  
  <pre><code>class Class1 implements Interface1, Interface2, Interface3, Interface4 {
     .....
  }
  </code></pre>
  
  <p>For all the similar examples I found, I've seen that there can be only 2 interfaces implemented by one class. But there isn't any info about what I'm looking for.</p>
