title: Problems to install php intl with Xampp (MacOs)
body: <p>I´m installed Xampp in my Mac, the last version with Php7, all works fine, but in my Php proyect I´m using this function:</p>
  
  <pre><code>numfmt_format_currency() 
  </code></pre>
  
  <p>I need install the intl, and edit the php.ini with this line:</p>
  
  <pre><code>extension="intl.so”
  </code></pre>
  
  <p>The problem is, I can´t install the intl, I use this command:</p>
  
  <pre><code>sudo pecl install intl
  </code></pre>
  
  <p>But returns me this console error:</p>
  
  <pre><code>/private/tmp/pear/temp/intl/intl_error.h:24:10: fatal error: 'ext/standard/php_smart_str.h' file not found
  #include &lt;ext/standard/php_smart_str.h&gt;
           ^
  1 error generated.
  make: *** [php_intl.lo] Error 1
  ERROR: `make' failed
  </code></pre>
  
  <p>After, I try download the ntl-3.0.0.tgz from <a href="http://pecl.php.net/package/intl" rel="noreferrer">here</a>, and Install whith this command:</p>
  
  <pre><code>sudo pear install intl-3.0.0.tgz
  </code></pre>
  
  <p>But return me this:</p>
  
  <pre><code>No releases available for package "pear.php.net/intl" - package pecl/intl can be installed with "pecl install intl"
  install failed
  </code></pre>
  
  <p>I'm desperate, how can I install intl?</p>
