| Because file and directory names can be strings that PHP considers "falsy" | ||
| (e.g. a directory named <literal>"0"</literal>) and | ||
| <function>readdir</function> returns &false; when it has read all entries | ||
| in a directory one needs to use the <literal>===</literal> | ||
| <link linkend="language.operators.comparison">comparison operator</link> | ||
| to properly distinguish between a directory entry whose name is "falsy" | ||
| and having read all entries of the directory. | ||
| </simpara> |
