Changes between Initial Version and Version 1 of Ticket #49853, comment 5

-                      initial
+                      v1
 In my testing `if ( trim( $post_title ) === '' )` works as expected and maintains the strict comparison:
+`$tests = array( 0, NULL, 'foo', '', '0' );
+{{{#!php
+<?php
+$tests = array( 0, NULL, 'foo', '', '0' );
 foreach ( $tests as $test ) {
         if ( '' === trim( $test ) ) {
 …
                 echo ' is empty!';
+        }
+}`
+}
+}}}
