Komentar Fungsi PHP


115

Hanya pertanyaan singkat: Saya telah melihat bahwa beberapa fungsi PHP dikomentari di bagian atas, menggunakan format yang tidak saya kenal:

/**
 *
 * Convert an object to an array
 *
 * @param    object  $object The object to convert
 * @return      array
 *
 */

IDE saya memberi saya pilihan dropdown untuk hal-hal seperti @param dan @return, jadi harus didokumentasikan di suatu tempat. Saya sudah mencoba mencari di Google tetapi tidak menyertakan simbol @ dalam pencariannya.

Apa format komentar ini dan di mana saya dapat menemukan beberapa informasi tentangnya?


@ Mr. Smith: dia mungkin menggunakan Eclipse

saat mencari di Google, gunakan tanda kutip ganda, seperti "@return" dan "@param" dan Anda akan menemukan sesuatu.

Itu sintaks phpDoc.

Sepertinya salinan javadoc.

Idenya sama, hanya untuk PHP, bukan Java.

Anda harus menjelaskan di sini, saya sudah melalui 1 klik untuk berada di sini, bahkan klik berikutnya tidak memberi saya jawaban, jawaban selanjutnya adalah apa yang saya cari dengan sempurna.

/**
 * 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.
 *
 * @category   CategoryName
 * @package    PackageName
 * @author     Original Author <author@example.com>
 * @author     Another Author <another@example.com>
 * @copyright  1997-2005 The PHP Group

    // {{{ properties

    /**
     * The status of foo's universe
     * Potential values are 'good', 'fair', 'poor' and 'unknown'.
     * @var string $foo

    public $foo = 'unknown';

     *
     * 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

Tidak perlu menggunakan tag "@access" karena tingkat akses sudah diketahui dari konstruksi "publik", "pribadi", atau "dilindungi" yang digunakan untuk mendeklarasikan fungsi.
