我在 Swoole 官網(wǎng)上下載了 SwooleCompilerLoader 卻發(fā)現(xiàn)只支持 php7.2 (最高)，現(xiàn)有php加密程序一個，不知道如何在不改變 PHP 版本下運行它？現(xiàn)在一運行l(wèi)oader就提示PHP Warning: PHP Startup: Unable to load dynamic library 'swoole_loader72' (tried: /usr/lib/php/20180731/swoole_loader72 (/usr/lib/php/20180731/swoole_loader72: cannot open shared object file: No such file or directory), /usr/lib/php/20180731/swoole_loader72.so (/usr/lib/php/20180731/swoole_loader72.so: undefined symbol: _zval_ptr_dtor)) in Unknown on line 0而我查了一下谷歌和文檔，并不知道 undefined symbol: _zval_ptr_dtor 是什么意思，請問有嘗試成功的嗎？
