为什么get_loaded_extensions不打印mysql相关模块?

Question

$aa = get_loaded_extensions();
print_r($aa);

Array ( [0] => Core [1] => date [2] => ereg [3] => libxml [4] => pcre [5] => sqlite3 [6] => ctype [7] => dom [8] => fileinfo [9] => filter [10] => hash [11] => iconv [12] => json [13] => SPL [14] => PDO [15] => pdo_sqlite [16] => session [17] => posix [18] => Reflection [19] => standard [20] => SimpleXML [21] => Phar [22] => tokenizer [23] => xml [24] => xmlreader [25] => xmlwriter [26] => apache2handler )

程序上传到服务器就提示:您的服务器不支持mysql，所以程序无法完成安装!。
但是在本地上是正常的..

这是本地的打印

Array ( [0] => Core [1] => bcmath [2] => calendar [3] => ctype [4] => date [5] => ereg [6] => filter [7] => ftp [8] => hash [9] => iconv [10] => json [11] => mcrypt [12] => SPL [13] => odbc [14] => pcre [15] => Reflection [16] => session [17] => standard [18] => mysqlnd [19] => tokenizer [20] => zip [21] => zlib [22] => libxml [23] => dom [24] => PDO [25] => Phar [26] => SimpleXML [27] => wddx [28] => xml [29] => xmlreader [30] => xmlwriter [31] => apache2handler [32] => curl [33] => gd [34] => intl [35] => imap [36] => mbstring [37] => mysql [38] => mysqli [39] => pdo_mysql [40] => sockets [41] => sqlite3 [42] => xmlrpc [43] => xsl [44] => mhash )

mysql mysqli pdo_mysql 在本地都有的..而在服务器没有??

Answer 1

那你开启啊，不是很清楚嘛，服务器上的mysqli 可能没开启！
