php 5.2.3+mysqli 安装与常见错误 总结
 
记得原来在编译php的已经已经加上参数
--with-mysql=/usr/local/mysql \
--with-mysqli=/usr/local/mysql/bin/mysql_config \
可后来找了一个，的确不存在mysqli.so，所以只能单独来编译mysqli了。
mysqli是优化过的mysql函数库，MYSQL版本不能低于4.1.12

cd /root/tmp/php-5.2.3/ext/mysqli
#####进入到mysqli的目录。
再用phpize生成configure文件:
/usr/local/bin/phpize
Configuring for:
PHP Api Version:         20041225
Zend Module Api No:      20060613
Zend Extension Api No:   220060519
#./configure --prefix=/usr/local/mysqli --with-php-config=/usr/local/bin/php-config --with-mysqli=/usr/bin/mysql_config
make
make install
Installing shared extensions:     /usr/local/lib/php/extensions/debug-non-zts-20060613/
然后在/usr/local/lib/php.ini
加上一句：
extension=/usr/local/lib/php/extensions/no-debug-non-zts-20060613/mysqli.so
重新启动apache即可看到已经加载mysqli成功。
 
 
1、如果出现出错代码：
 
 
  1. /root/tmp/php-5.2.3/ext/mysqli/mysqli.c: In function 'zm_startup_mysqli':
  2. /root/tmp/php-5.2.3/ext/mysqli/mysqli.c:637: error: 'MYSQL_RPL_MASTER' undeclared (first use in this function)
  3. /root/tmp/php-5.2.3/ext/mysqli/mysqli.c:637: error: (Each undeclared identifier is reported only once
  4. /root/tmp/php-5.2.3/ext/mysqli/mysqli.c:637: error: for each function it appears in.)
  5. /root/tmp/php-5.2.3/ext/mysqli/mysqli.c:638: error: 'MYSQL_RPL_SLAVE' undeclared (first use in this function)
  6. /root/tmp/php-5.2.3/ext/mysqli/mysqli.c:639: error: 'MYSQL_RPL_ADMIN' undeclared (first use in this function)
  7. *** Error code 1
 
修改一下这个文件就可以

cd /usr/include/mysql
root@www[/usr/include/mysql]# vi mysql.h

  在第221行
 
 
  1. ... ...
  2. enum mysql_protocol_type
  3. {
  4. MYSQL_PROTOCOL_DEFAULT, MYSQL_PROTOCOL_TCP, MYSQL_PROTOCOL_SOCKET,
  5. MYSQL_PROTOCOL_PIPE, MYSQL_PROTOCOL_MEMORY
  6. };
  7. /*
  8. There are three types of queries - the ones that have to go to
  9. the master, the ones that go to a slave, and the adminstrative
  10. type which must happen on the pivot connectioin
  11. */


#添加下面的4行
 
 
  1. enum mysql_rpl_type
  2. {
  3. MYSQL_RPL_MASTER, MYSQL_RPL_SLAVE, MYSQL_RPL_ADMIN
  4. };

 
2、如果出现以下错误：
/root/tmp/php-5.2.3/ext/mysqli/mysqli_api.c: In function 'zif_mysqli_stmt_bind_param':
/root/tmp/php-5.2.3/ext/mysqli/mysqli_api.c:144: error: 'gptr' undeclared (first use in this function)
/root/tmp/php-5.2.3/ext/mysqli/mysqli_api.c:144: error: (Each undeclared identifier is reported only once
/root/tmp/php-5.2.3/ext/mysqli/mysqli_api.c:144: error: for each function it appears in.)
/root/tmp/php-5.2.3/ext/mysqli/mysqli_api.c: In function 'zif_mysqli_stmt_execute':
/root/tmp/php-5.2.3/ext/mysqli/mysqli_api.c:603: error: 'gptr' undeclared (first use in this function)
make: *** [mysqli_api.lo] 错误 1
 
修改一下这个文件就可以
vi mysqli_api.c
查找所有 gptr，有四处分别位于行144、行150、行603、行607，以 char* 替换
 

测试Mysqli运行状况：
Vim mysqli.php
$mysqli = new mysqli("localhost", "my_user", "my_password", "dbname");
/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}
printf("Host information: %s\n", $mysqli->host_info);
/* close connection */
$mysqli->close();
?>
