title: How to Gammu sendsms php shell_exec windows 7 and xampp?
body: <p>I have already installed XAMPP latest version and installed gammu.</p>
  
  <p>In terminal I can send sms or identify my cellphone, but if i try the same command on php shell_exec or exec there is something wrong.</p>
  
  <p>The command:</p>
  
  <pre><code>"C:\Program Files\gammu\bin\gammu.exe" --sendsms TEXT 06706177529 -text "halooo"
  This works.
  </code></pre>
  
  <p>The command in php:</p>
  
  <pre><code>$a = shell_exec('"C:\Program Files\gammu\bin\gammu.exe" --sendsms TEXT 06706177529 -text "halooo"');
  </code></pre>
  
  <p>This write to me:</p>
  
  <blockquote>
    <p>Warning: No configuration file found! Warning: No configuration read,
    using builtin defaults! Error opening device, it doesn't exist.</p>
  </blockquote>
  
  <p>What can be wrong?</p>
