不曉得 GCP Cloud Functions 到底對 PHP 支援多少東西，畢竟很多功能需要安裝 extensions，因此寫個 script 列出環境中可用的 extensions：

<?php

var_dump(get_loaded_extensions());

不過很意外得發現幾乎所有 extensions 都可以用：

Array
(
    [0] => Core
    [1] => date
    [2] => libxml
    [3] => openssl
    [4] => pcre
    [5] => sqlite3
    [6] => zlib
    [7] => bcmath
    [8] => bz2
    [9] => calendar
    [10] => ctype
    [11] => curl
    [12] => dba
    [13] => dom
    [14] => enchant
    [15] => hash
    [16] => fileinfo
    [17] => filter
    [18] => ftp
    [19] => gd
    [20] => gettext
    [21] => gmp
    [22] => SPL
    [23] => iconv
    [24] => intl
    [25] => json
    [26] => ldap
    [27] => mbstring
    [28] => session
    [29] => pcntl
    [30] => PDO
    [31] => standard
    [32] => pdo_pgsql
    [33] => pdo_sqlite
    [34] => pgsql
    [35] => Phar
    [36] => posix
    [37] => Reflection
    [38] => mysqlnd
    [39] => shmop
    [40] => SimpleXML
    [41] => soap
    [42] => sockets
    [43] => pdo_mysql
    [44] => exif
    [45] => sysvshm
    [46] => tidy
    [47] => tokenizer
    [48] => xml
    [49] => xmlreader
    [50] => xmlrpc
    [51] => xmlwriter
    [52] => xsl
    [53] => zend-test
    [54] => zip
    [55] => mysqli
    [56] => cgi-fcgi
    [57] => Zend OPcache
)

看了 example code，也可以使用 composer，這樣彈性非常大。搞不好可以把一些服務直接搬過去了。
