                **一.不建議使用PostgreSQL的別名函數** #PHP 8不贊成PostgreSQL擴展中的24個函數別名 不推薦使用的功能 用以下函數來代替 -------------------------------------------------- ``` pg_clientencoding pg_client_encoding pg_cmdtuples pg_affected_rows pg_errormessage pg_last_error pg_fieldisnull pg_field_is_null pg_fieldname pg_field_name pg_fieldnum pg_field_num pg_fieldprtlen pg_field_prtlen pg_fieldsize pg_field_size pg_fieldtype pg_field_type pg_freeresult pg_free_result pg_getlastoid pg_last_oid pg_loclose pg_lo_close pg_locreate pg_lo_create pg_loexport pg_lo_export pg_loimport pg_lo_import pg_loopen pg_lo_open pg_loread pg_lo_read pg_loreadall pg_lo_read_all pg_lounlink pg_lo_unlink pg_lowrite pg_lo_write pg_numfields pg_num_fields pg_numrows pg_num_rows pg_result pg_fetch_result pg_setclientencoding pg_set_client_encoding ``` &emsp; **二.安裝postgresql數據** #為了速度快一些使用yum來安裝 ``` yum -y install postgresql* postgresql-devel ``` &emsp; **三.給PHP8打pgsql.so擴展模塊** 1.進入pgsql模塊目錄 ``` cd /mnt/php-8.0.0/ext/pgsql ``` 2.phpize生成configure ``` /usr/local/php/bin/phpize ``` 3.php-config編譯so文件 ``` ./configure --with-php-config=/usr/local/php/bin/php-config make && make install ``` &emsp; **四.配置php支持postgresql函數集** #php.ini ``` extension=pgsql.so ``` #.查看pgsql模塊 ``` phpinfo(); ``` &emsp; **五.測試pg_numrows和pg_num_rows函數支持情況** ``` pg_numrows(); Deprecated: Function pg_numrows() is deprecated pg_num_rows(); Fatal error: Uncaught ArgumentCountError: pg_num_rows() expects exactly 1 argument, 0 given ``` &emsp; **配套的PHP8新特性詳解視頻教程,請查看以下專輯** 鏈接:[https://www.ixigua.com/6937490165329822219](https://www.ixigua.com/6937490165329822219)
