范例

bindtextdomain() example

<?php
$domain = 'myapp';
echo bindtextdomain($domain, '/usr/share/myapp/locale');
?>

以上例程会输出：

/usr/share/myapp/locale

I recommend using absolute paths in the $directory parameter. This caused me several hours to debug as Ajax calls to my localization functions messed up the path. And since no error if thrown if the path in $directory cannot be found, one should check the result always:
<?php
  // Imagine the path for this file is "/localization" and your locales are in the "/locale" directory.
  $pathToDomain = __DIR__ . "/../locale";
  if ($pathToDomain != bindtextdomain($domain, $pathToDomain)) {
    // Error handling.
  }
?>

The name of your .mo file must match the $domain, e.g. name your files messages.mo and call bindtextdomain("messages", $directory).
