php扩展实践之数组操作

初始化数组

zval *arr;
MAKE_STD_ZVAL(arr);
array_init(arr);

插入和更新

// 索引
add_index_bool(arr, 10, 1);
add_next_index_long(arr, 1000);
// 关联数组
add_assoc_stringl(arr, "name", ZEND_STRL("xiaozi"), 1);

查找和删除

char *name = "name";
int nameLen = strlen(name);
// 查找
zend_hash_exists(Z_ARRVAL_P(arr), name, nameLen + 1);
// 删除
zend_hash_del(Z_ARRVAL_P(arr), name, nameLen + 1);

读取

char *name = "name";
int nameLen = strlen(name);
zval **value;
if (zend_hash_find(Z_ARRVAL_P(attributes), name, nameLen + 1, (void **)&value) == SUCCESS) {
    php_var_dump(value, 1 TSRMLS_CC);
}
