PHP：按类分组的所有函数列表

I am looking for a way to get a list of all the php functions but needed them group by the class they exist in. Not sure if there is a way to get this from PHP docs or if its built into PHP. I am really only looking for built in / popular classes, so a custom mysqli class I dont care about but the mysql library that can be installed with PHP I do need.

Thank you very much

Try this:

foreach(get_declared_classes() as $classname) {
    echo $classname . PHP_EOL;
    $class = new ReflectionClass($classname);
    foreach($class->getMethods() as $m) {
        echo '  ' . $m->name . PHP_EOL;
    }
}

I'm using get_declared_classes() to get a list of all declared classes. Then I create a ReflectionClass object from them and iterate throught their methods.
