PHP函数注释
只是一个简单的问题：我已经看到一些PHP函数在顶部被评论，使用我未知的格式：
/**
*
* Convert an object to an array
*
* @param object $object The object to convert
* @return array
*
*/
我的IDE为我提供了一个下拉选择，例如@param和@return，所以它必须记录在某处。 我试过搜索谷歌，但它不会在搜索中包含@符号。
这种评论形式是什么，我可以在哪里找到关于它的一些信息？
这是phpDoc语法。

/**
* An example of how to write code to PEAR's standards
*
* Docblock comments start with "/**" at the top. Notice how the "/"
* lines up with the normal indenting and the asterisks on subsequent rows
* are in line with the first asterisk. The last line of comment text
* should be immediately followed on the next line by the closing asterisk
* and slash and then the item you are commenting on should be on the next
* line below that. Don't add extra lines. Please put a blank line
* between paragraphs as well as between the end of the description and
* the start of the @tags. Wrap comments before 80 columns in order to
* ease readability for a wide variety of users.
*
* Docblocks can only be used for programming constructs which allow them
* (classes, properties, methods, defines, includes, globals). See the
* phpDocumentor documentation for more information.
* http://phpdoc.org/tutorial_phpDocumentor.howto.pkg.html
*
* The Javadoc Style Guide is an excellent resource for figuring out
* how to say what needs to be said in docblock comments. Much of what is
* written here is a summary of what is found there, though there are some
* cases where what's said here overrides what is said there.
* http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#styleguide
*
* The first line of any docblock is the summary. Make them one short
* sentence, without a period at the end. Summaries for classes, properties
* and constants should omit the subject and simply state the object,
* because they are describing things rather than actions or behaviors.
*
* Below are the tags commonly used for classes. @category through @version
* are required. The remainder should only be used when necessary.
* Please use them in the order they appear here. phpDocumentor has
* several other tags available, feel free to use them.
*

* @package PackageName

// {{{ properties
/**
* The status of foo's universe
* Potential values are 'good', 'fair', 'poor' and 'unknown'.
* @var string $foo
*/
public $foo = 'unknown';
/**
* The status of life
* Note that names of private properties or methods must be
* preceeded by an underscore.
* @var bool $_good
*/
private $_good = true;
// }}}
// {{{ setFoo()
/**
* Registers the status of foo's universe
*
* Summaries for methods should use 3rd person declarative rather
* than 2nd person imperative, beginning with a verb phrase.
*
* Summaries should add description beyond the method's name. The
* best method names are "self-documenting", meaning they tell you
* basically what the method does. If the summary merely repeats
* the method name in sentence form, it is not providing more
* information.
*
* Summary Examples:
* + Sets the label (preferred)
* + Set the label (avoid)
* + This method sets the label (avoid)
*
* Below are the tags commonly used for methods. A @param tag is
* required for each parameter the method has. The @return
* and @access tags are mandatory. The @throws tag is required if
* the method uses exceptions. @static is required if the method can
* be called statically. The remainder should only be used when
* necessary. Please use them in the order they appear here.
* phpDocumentor has several other tags available, feel free to use
* them.
*
* The @param tag contains the data type, then the parameter's
* name, followed by a description. By convention, the first noun in
* the description is the data type of the parameter. Articles like
* "a", "an", and "the" can precede the noun. The descriptions
* should start with a phrase. If further description is necessary,
* follow with sentences. Having two spaces between the name and the
* description aids readability.
*
* When writing a phrase, do not capitalize and do not end with a
* period:
* + the string to be tested
*
* When writing a phrase followed by a sentence, do not capitalize the
* phrase, but end it with a period to distinguish it from the start
* of the next sentence:
* + the string to be tested. Must use UTF-8 encoding.
*
* Return tags should contain the data type then a description of
* the data returned. The data type can be any of PHP's data types
* (int, float, bool, string, array, object, resource, mixed)
* and should contain the type primarily returned. For example, if
* a method returns an object when things work correctly but false
* when an error happens, say 'object' rather than 'mixed.' Use
* 'void' if nothing is returned.
*
* Here's an example of how to format examples:
* <code>
* require_once 'Net/Sample.php';
*
* $s = new Net_Sample();
* if (PEAR::isError($s)) {
* echo $s->getMessage() . "n";
* }
* </code>
*
* Here is an example for non-php example or sample:
* <samp>
* pear install net_sample
* </samp>
*
* @param string $arg1 the string to quote
* @param int $arg2 an integer of how many problems happened.
* Indent to the description's starting point
* for long ones.
*
* @return int the integer of the set mode used. FALSE if foo
* foo could not be set.
* @throws exceptionclass [description]
*
* @access public
* @static
* @see Net_Sample::$foo, Net_Other::someMethod()
* @since Method available since Release 1.2.0
* @deprecated Method deprecated in Release 2.0.0
*/
function setFoo($arg1, $arg2 = 0)
{
/*
* This is a "Block Comment." The format is the same as
* Docblock Comments except there is only one asterisk at the
* top. phpDocumentor doesn't parse these.
*/
if ($arg1 == 'good' || $arg1 == 'fair') {
$this->foo = $arg1;
return 1;
} elseif ($arg1 == 'poor' && $arg2 > 1) {
$this->foo = 'poor';
return 2;
} else {
return false;
}
}
// }}}
}
// }}}
/*
* Local variables:
* tab-width: 4
* c-basic-offset: 4
* c-hanging-comment-ender-p: nil
* End:
