返回指定字段的字段标志。每个标志都用一个单词表示，之间用一个空格分开，因此可以用
|
|
<span class="function"><a href="explode.html" class="function">explode()</a></span> 将其分开。

如果 MySQL 版本足够新，则会支持以下的标志："not_null", "primary_key",
|
|
"unique_key", "multiple_key", "blob", "unsigned", "zerofill",
|
|
"binary", "enum", "auto_increment", "timestamp"。

为向下兼容仍然可以使用
|
|
<span class="function"><strong>mysql_fieldflags()</strong></span>，但反对这样做。
