求助，为什么用C方法修改配置文件，不能修改多次，具体如下

array(7) { ["DB_TYPE"] => string(6) "sqlsrv" ["DB_NAME"] => string(6) "FMS_DB" ["DB_PARAMS"] => array(1) { [8] => int(2) } ["DB_USER"] => string(2) "sa" ["DB_PWD"] => string(8) "1qaz2wsx" ["DB_CHARSET"] => string(4) "utf8" ["DB_HOST"] => st... array(7) { ["DB_TYPE"] => string(6) "sqlsrv" ["DB_NAME"] => string(6) "FMS_DB" ["DB_PARAMS"] => array(1) { [8] => int(2) } ["DB_USER"] => string(2) "sa" ["DB_PWD"] => string(8) "1qaz2wsx" ["DB_CHARSET"] => string(4) "utf8" ["DB_HOST"] => string(12) "192.168.1.77"} IP为192.168.1.77的数据数量：204 array(7) { ["DB_TYPE"] => string(6) "sqlsrv" ["DB_NAME"] => string(6) "FMS_DB" ["DB_PARAMS"] => array(1) { [8] => int(2) } ["DB_USER"] => string(2) "sa" ["DB_PWD"] => string(8) "1qaz2wsx" ["DB_CHARSET"] => string(4) "utf8" ["DB_HOST"] => string(9) "127.0.0.1"} IP为127.0.0.1的数据数量：204 array(7) { ["DB_TYPE"] => string(6) "sqlsrv" ["DB_NAME"] => string(6) "FMS_DB" ["DB_PARAMS"] => array(1) { [8] => int(2) } ["DB_USER"] => string(2) "sa" ["DB_PWD"] => string(8) "1qaz2wsx" ["DB_CHARSET"] => string(4) "utf8" ["DB_HOST"] => string(5) "192.1"} IP为192.1的数据数量：204 上面是配置输出，理论上来说每个IP的数据数量是不一样的，还有为什么就是192.1没有这个ip也可以输出？
