我专门搜索get_string函数定义，但想知道是否有所有moodle 2.7函数的列表以及在哪里找到它们。
答案 0 :(得分：0)
大多数函数使用phpdoc块并且通常比在线文档更新 - 如果您使用的是体面的IDE，那么它将显示定义 - 您还可以提取所有文档块http://www.phpdoc.org/docs/latest/getting-started/your-first-set-of-documentation.html < / p>
您还可以尝试使用api的在线开发者文档 - 这是Strings API的文档

Moodle 2.5中的get_string（）的phpdoc定义：
/**
* Returns a localized string.
*
* Returns the translated string specified by $identifier as
* for $module. Uses the same format files as STphp.
* $a is an object, string or number that can be used
* within translation strings
*
* eg 'hello {$a->firstname} {$a->lastname}'
* or 'hello {$a}'
*
* If you would like to directly echo the localized string use
* the function {@link print_string()}
*
* Example usage of this function involves finding the string you would
* like a local equivalent of and using its identifier and module information
* to retrieve it.<br/>
* If you open moodle/lang/en/moodle.php and look near line 278
* you will find a string to prompt a user for their word for 'course'
* <code>
* $string['course'] = 'Course';
* </code>
* So if you want to display the string 'Course'
* in any language that supports it on your site
* you just need to use the identifier 'course'
* <code>
* $mystring = '<strong>'. get_string('course') .'</strong>';
* or
* </code>
* If the string you want is in another file you'd take a slightly
* different approach. Looking in moodle/lang/en/calendar.php you find
* around line 75:
* <code>
* $string['typecourse'] = 'Course event';
* </code>
* If you want to display the string "Course event" in any language
* supported you would use the identifier 'typecourse' and the module 'calendar'
* (because it is in the file calendar.php):
* <code>
* $mystring = '<h1>'. get_string('typecourse', 'calendar') .'</h1>';
* </code>
*
* As a last resort, should the identifier fail to map to a string
* the returned string will be [[ $identifier ]]
*
* In Moodle 2.3 there is a new argument to this function $lazyload.
* Setting $lazyload to true causes get_string to return a lang_string object
* rather than the string itself. The fetching of the string is then put off until
* the string object is first used. The object can be used by calling it's out
* method or by casting the object to a string, either directly e.g.
* (string)$stringobject
* or indirectly by using the string within another string or echoing it out e.g.
* echo $stringobject
* return "<p>{$stringobject}</p>";
* It is worth noting that using $lazyload and attempting to use the string as an
* array key will cause a fatal error as objects cannot be used as array keys.
* But you should never do that anyway!
* For more information {@see lang_string}
*
* @category string
* @param string $identifier The key identifier for the localized string
* @param string $component The module where the key identifier is stored,
* usually expressed as the filename in the language pack without the
* .php on the end but can also be written as mod/forum or grade/export/xls.
* If none is specified then moodle.php is used.
* @param string|object|array $a An object, string or number that can be used
* within translation strings
* @param bool $lazyload If set to true a string object is returned instead of
* the string itself. The string then isn't calculated until it is first used.
* @return string The localized string.
