title: Wildcards in php's strpos function
body: <p>I'm looking for some wildcards to the <code>strpos</code> function similar to those used in <code>preg_replace</code> or <code>preg_match</code> but I can't find any, here is an idea:</p>
  
  <pre><code>&lt;?php
  if (strpos("The black\t\t\thorse", "black horse") === false)
    echo "Text NOT found.";
  else
    echo "Text found.";
  ?&gt;
  </code></pre>
  
  <p>Here the result will be: <code>Text NOT found.</code></p>
  
  <p>Now I want to use one wildcard to omit spaces or horizontal tab like below:</p>
  
  <pre><code>&lt;?php
  if (strpos("The black\t\t\thorse", "black/*HERE THE WILDCARD*/horse") === false)
    echo "Text NOT found.";
  else
    echo "Text found.";
  ?&gt;
  </code></pre>
  
  <p>And here the idea is that the result is: <code>Text found.</code></p>
  
  <p>Does anyone know something about ?</p>
