我已经使用netbeans 7.3为PHP中的类属性编写了一个docblock注释。被注释的属性是一个关联数组，所以我想对每个键进行注释。这是代码：
/**
* The expression being built.
*
* This will be pushed to the {@see $_parts} array when complete.
* <code>
* array(
* 'schema', # The qualified schema name
* 'table', # The qualified table name
* 'column', # The qualified column name
* 'alias', # A simple name for schema.table.column
* 'expr' # A nested (in parenthesis) Expression object.
* 'raw' # Used for unrecognized expressions.
* 'operator', # The operator comparing column and value
* 'value', # The value(s) to compare column against
* 'eval' # A callable method to do the compare.
* 'query' # A sub Query (or Transaction) object.
* )
* </code>
*
* @var mixed[]
*/
protected $_unit = array();
我希望<code>块能够保留行格式。问题是，当使用"自动弹出文档窗口"时，注释中的换行符被忽略，所有多个空格都被压缩为一个空格。这使得它很难阅读。
有没有其他方法可以保存格式，或者至少使其可读？
在<code>标签周围使用<pre>标签。否则只使用<br>。
从phpDocumentor:
<code> -- Use this to surround php code, some converters will highlight it
<pre> -- Preserve line breaks and spacing, and assume all tags are text (like XML's CDATA)
<br> -- hard line break, may be ignored by some converters
示例：
/**
* The expression being built.
*
* This will be pushed to the {@see $_parts} array when complete.
* <pre>
* <code>
* array(
* 'schema', # The qualified schema name
* 'table', # The qualified table name
* 'column', # The qualified column name
* 'alias', # A simple name for schema.table.column
* 'expr' # A nested (in parenthesis) Expression object.
* 'raw' # Used for unrecognized expressions.
* 'operator', # The operator comparing column and value
* 'value', # The value(s) to compare column against
* 'eval' # A callable method to do the compare.
* 'query' # A sub Query (or Transaction) object.
* )
* </code>
* </pre>
*
* @var mixed[]
