    destructors

    destructors 块如下所示:

    1. {
    2.     "destructors": [
    3.         {
    4.             "request": [
    5.                 {
    6.                     "include": "my/awesome/library.h",
    7.                     "code": "c_function_for_shutting_down(TSRMLS_C)"
    8.                 },
    9.                 {
    10.                     "include": "my/awful/library.h",
    11.                     "code": "some_other_c_function_than_the_other_ones(TSRMLS_C)"
    12.                 }
    13.             ],
    14.             "post-request": [
    15.                 {
    16.                     "include": "my/awesome/library.h",
    17.                     "code": "c_function_for_cleaning_up_after_the_response_is_sent(TSRMLS_C)"
    18.                 }
    19.             ],
    20.             "module": [
    21.                 {
    22.                     "include": "my/awesome/library.h",
    23.                     "code": "release_module_deps(TSRMLS_C)"
    24.                 }
    25.             ],
    26.             "globals": [
    27.                 {
    28.                     "include": "my/awesome/library.h",
    29.                     "code": "release_globals_deps(TSRMLS_C)"
    30.                 }
    31.             ]
    32.         }
    33.     ]
    34. }

    正如 initializers 块负责定义上图中显示的 init 事件中的挂钩一样, this 块负责定义关机事件中的挂钩。 有四个:request响应之前敲定任何数据发送到客户端,post-request清理响应被发送后,module</0 >模块扩展后的清理本身PHP进程关闭之前, 和<code>globals清理全局变量空间。
