sanitize_title( string $title, string $fallback_title = '', string $context = 'save' ): string

Sanitizes a string into a slug, which can be used in URLs or HTML attributes.


By default, converts accent characters to ASCII characters and further limits the output to alphanumeric characters, underscore (_) and dash (-) through the ‘sanitize_title’ filter.

If $title is empty and $fallback_title is set, the latter will be used.

    WordPress Titles
    To create the file name portion of a URL the same way that WordPress does use this:

      $new_url = sanitize_title('This Long Title is what My Post or Page might be');
      echo $new_url;

    It should return a formatted value, the output would be this:

    As was noted in the codex reference page for this function:

    Despite the name of this function, the returned value is intended to be suitable for use in a URL, not as a human-readable title.

    So My Excellent Sentence becomes my-excellent-sentence for example.

    This is because this function applies a filter of the same name to which Wordpress adds sanitize_title_with_dashes by default.
