- 配置文件PHP.ini修改

打开; extension_dir = "ext"，修改成

; extension_dir = "./"
; On windows:
extension_dir = "自己php的存放路径\ext"

2.打开extension=msql.dll

; For example, on Windows:
;
   extension=msql.dll

3.修改配置（直接粘贴过去即可）

extension=php_bz2.dll
extension=php_curl.dll
extension=php_fileinfo.dll
extension=php_gd2.dll
extension=php_gettext.dll
;extension=php_gmp.dll
;extension=php_intl.dll
;extension=php_imap.dll
;extension=php_interbase.dll
;extension=php_ldap.dll
extension=php_mbstring.dll
extension=php_exif.dll      ; Must be after mbstring as it depends on it
extension=php_mysql.dll
extension=php_mysqli.dll
;extension=php_oci8.dll      ; Use with Oracle 10gR2 Instant Client
;extension=php_oci8_11g.dll  ; Use with Oracle 11gR2 Instant Client
extension=php_openssl.dll
;extension=php_pdo_firebird.dll
extension=php_pdo_mysql.dll

;extension=php_snmp.dll
 
extension=php_soap.dll
extension=php_sockets.dll
extension=php_sqlite3.dll
;extension=php_sybase_ct.dll
extension=php_tidy.dll
extension=php_xmlrpc.dll
extension=php_xsl.dll

4.修改配置时间

[Date]
; Defines the default timezone used by the date functions
; https://php.net/date.timezone
date.timezone = Asia/Shanghai

2.SQl端配置修改

php5+SQL8报错SERVER SENT CHARSET (255) UNKNOWN和(HY000/2054)的解决方法:

原本运行好好的php，重启了一下后，报错，但是apache24，php5.5，mysql8.0都设置好了，报错内容为：

mysqli_real_connect(): Server sent charset (255) unknown to the client. Please, report to the developers

mysqli_real_connect(): (HY000/2054): Server sent charset unknown to the client. Please, report to the developers

这是因为在MySQL 8.0.11中，caching_sha2_password是默认的身份验证插件，而不是以往的mysql_native_password。所以和php不兼容。可以降级php，也可以修改MySQL的配置。

我决定修改MySQL的配置。

可是我进入C:\Program Files\MySQL\MySQL Server 8.0,怎么也找不到配置文件（my.ini或者mysqld.cnf）。

最后在隐藏文件夹ProgramData里找到了，完整路径是C:\ProgramData\MySQL\MySQL Server 8.0\my.ini打开my.ini做如下配置：

[mysqld]
port=3306
character-set-server=utf8
default_authentication_plugin=mysql_native_password
[mysql]
default-character-set=utf8
[client]
default-character-set=utf8
