 Since 5.1 the `sanitize_text_field` changed to check if the parameter is
 an object or array.
 That broken one of my codes and possibly for other people too because I
 was passing a `SimpleXMLElement Object`. It has a magic `__toString()`
 method that gets called when you do that type conversion.

 As @iCaleb suggested in #41450, we may want to add another check.


 {{{#!php
 <?php
 if ( ( is_object( $str ) && ! method_exists( $str, '__toString' ) ) ||
 is_array( $str ) ) {
   return '';
 }
 }}}
