Note that this function also counts enums.<?phpenum Bla{ case Foo;}var_dump(get_declared_classes());?>Result:array(116) { ... [115]=> string(3) "Bla"}
(PHP 4, PHP 5, PHP 7, PHP 8)
get_declared_classes — 返回由已定义类的名字所组成的数组
此函数没有参数。
返回由当前脚本中已定义类的名字组成的数组。
注意:
需要注意的是额外类的出现依赖于你已编译到 PHP 中的库。这意味着你不能使用这些类名定义自己的类。在附录的 预定义类 部分有预定义类的列表。
| 版本 | 说明 |
|---|---|
| 7.4.0 | 之前 get_declared_classes() 返回的顺序总是父类在前，子类在后。现在不会这样了。get_declared_classes() 的返回值将不再保证顺序。 |
示例 #1 get_declared_classes() 示例
<?php
print_r(get_declared_classes());
?>以上示例的输出类似于：
Array
(
[0] => stdClass
[1] => __PHP_Incomplete_Class
[2] => Directory
)
Note that this function also counts enums.<?phpenum Bla{ case Foo;}var_dump(get_declared_classes());?>Result:array(116) { ... [115]=> string(3) "Bla"}The array returned by this function will be in the order the classes were defined / included / required and this order does not appear to change.For example:<?PHP//define classoneclass classone { }//define classtwoclass classtwo { }//This will show X classes (built-ins, extensions etc) with//classone and classtwo as the last two elementsprint_r(get_declared_classes());//define classthreeclass classthree { }//...and fourclass classfour { }//Shows the same result as before with class three and four appendedprint_r(get_declared_classes());?>Output:Array( [0] => stdClass [1] .... other defined classes.... [10] => classone [11] => classtwo )and...Array( [0] => stdClass [1] .... other defined classes.... [10] => classone [11] => classtwo [12] => classthree [13] => classfour)
