是否有任何方法可以访问已注册的关闭功能列表?
答案 0 :(得分:10)
您可以撰写扩展程序并查看BG(user_shutdown_function_names)
。可能更容易为register_shutdown_function
创建一个包装器,将关闭函数保存到某个数组并调用它。
(未测试的)
#include "ext/standard/basic_functions.h"
//usual include suspects here
typedef struct _php_shutdown_function_entry {
zval **arguments;
int arg_count;
} php_shutdown_function_entry;
static void _shutdown_function_dtor(php_shutdown_function_entry *shutdown_function_entry) /* {{{ */
{
int i;
for (i = 0; i < shutdown_function_entry->arg_count; i++) {
zval_ptr_dtor(&shutdown_function_entry->arguments[i]);
}
efree(shutdown_function_entry->arguments);
}
static int _build_shutdown_array(php_shutdown_function_entry *entry, zval *arr TSRMLS_DC)
{
zval *inner;
zval *args;
int i;
array_init(inner);
array_init(args);
Z_ADDREF_P(entry->arguments[0]);
add_assoc_zval(inner, "callback", entry->arguments[0]);
for (i = 1; i < entry->arg_count; i++) {
Z_ADDREF_P(entry->arguments[i]);
add_next_index_zval(args, entry->arguments[i]);
}
add_assoc_zval(inner, "arguments", args);
add_next_index_zval(arr, inner);
}
PHP_FUNCTION(list_shutdown_functions)
{
if (zend_parse_parameters_none() == FAILURE)
return;
if (!BG(user_shutdown_function_names)) {
ALLOC_HASHTABLE(BG(user_shutdown_function_names));
zend_hash_init(BG(user_shutdown_function_names), 0, NULL,
(void (*)(void *)) _shutdown_function_dtor, 0);
}
array_init(return_value);
zend_hash_apply_with_argument(BG(user_shutdown_function_names),
(apply_func_arg_t) _build_shutdown_array, return_value TSRMLS_CC);
}

除了跟踪自己之外,没有。已注册的函数名列表未公开给您的PHP脚本。如果您愿意扩展PHP本身(这将是一项简单的任务),那么请参阅Artefacto的答案。
