title: PHP & Oracle - oci_connect() ORA-12705: Cannot access NLS data files
body: <p>We've been using Oracle on our server for years, but someone from IT removed it yesterday without clear warning and it's really thrown our systems!</p>
  
  <p>I've acted on the advice from cwallenpoole (thank you!) and have made good progress, and PHP is now at least including the oracle functions (ie oci_connect) but I am now experiencing another error message:</p>
  
  <p>"<strong>Warning: oci_connect() [function.oci-connect]: ORA-12705: Cannot access NLS data files or invalid environment</strong>"</p>
  
  <p>We have ensured the tnsnames.ora etc files are in the correct place, but still having no joy :(</p>
  
  <p>thank you</p>
