用的是Zookeeper扩展，Php版本为7.2.17，下载地址：
https://pecl.php.net/package/zookeeper
用的是0.6.4版本
创建节点官方给的示例如下：
<?php
$zookeeper = new Zookeeper(‘locahost:2181‘);
$aclArray = array(
array(
‘perms‘ => Zookeeper::PERM_ALL,
‘scheme‘ => ‘world‘,
‘id‘ => ‘anyone‘,
)
);
$path = ‘/path/to/newnode‘;
$realPath = $zookeeper->create($path, null, $aclArray);
if ($realPath)
echo $realPath;
else
echo ‘ERR‘;
?>
一直报无效的acl，查看源代码：
static void php_parse_acl_list(zval *z_acl, struct ACL_vector *aclv) { int size = 0; int i = 0; #ifdef ZEND_ENGINE_3 ulong index = 0; zend_string *key; zval *entry = NULL; zval *perms = NULL; zval *scheme = NULL; zval *id = NULL; #else zval **entry; zval **perms, **scheme, **id; #endif if (!z_acl || (size = zend_hash_num_elements(Z_ARRVAL_P(z_acl))) == 0) { return; } aclv->data = (struct ACL *)calloc(size, sizeof(struct ACL)); #ifdef ZEND_ENGINE_3 ZEND_HASH_FOREACH_KEY_VAL(Z_ARRVAL_P(z_acl), index, key, entry) { if( Z_TYPE_P(entry) != IS_ARRAY ) { continue; } perms = zend_hash_str_find(Z_ARRVAL_P(entry), ZEND_STRL("perms")); scheme = zend_hash_str_find(Z_ARRVAL_P(entry), ZEND_STRL("scheme")); id = zend_hash_str_find(Z_ARRVAL_P(entry), ZEND_STRL("id")); if (perms == NULL || scheme == NULL || id == NULL) { continue; } convert_to_long_ex(perms); convert_to_string_ex(scheme); convert_to_string_ex(id); aclv->data[i].perms = (int32_t)Z_LVAL_P(perms); aclv->data[i].id.id = strdup(Z_STRVAL_P(id)); aclv->data[i].id.scheme = strdup(Z_STRVAL_P(scheme)); i++; } ZEND_HASH_FOREACH_END(); #else for (zend_hash_internal_pointer_reset(Z_ARRVAL_P(z_acl)); zend_hash_get_current_data(Z_ARRVAL_P(z_acl), (void**)&entry) == SUCCESS; zend_hash_move_forward(Z_ARRVAL_P(z_acl))) { if (Z_TYPE_PP(entry) != IS_ARRAY) { continue; } perms = scheme = id = NULL; zend_hash_find(Z_ARRVAL_PP(entry), ZEND_STRS("perms"), (void**)&perms); zend_hash_find(Z_ARRVAL_PP(entry), ZEND_STRS("scheme"), (void**)&scheme); zend_hash_find(Z_ARRVAL_PP(entry), ZEND_STRS("id"), (void**)&id); if (perms == NULL || scheme == NULL || id == NULL) { continue; } convert_to_long_ex(perms); convert_to_string_ex(scheme); convert_to_string_ex(id); aclv->data[i].perms = (int32_t)Z_LVAL_PP(perms); aclv->data[i].id.id = strdup(Z_STRVAL_PP(id)); aclv->data[i].id.scheme = strdup(Z_STRVAL_PP(scheme)); i++; } #endif aclv->count = i; }
源码里把acl参数当作数组的数组了，所以调整下就可以了：
<?php
$zookeeper = new Zookeeper(‘locahost:2181‘);
$aclArray = [];
$aclArray[] = array(
array(
‘perms‘ => Zookeeper::PERM_ALL,
‘scheme‘ => ‘world‘,
‘id‘ => ‘anyone‘,
)
);
$path = ‘/path/to/newnode‘;
$realPath = $zookeeper->create($path, null, $aclArray);
if ($realPath)
echo $realPath;
else
echo ‘ERR‘;
?>
