在此php配置中启用了mysqli扩展吗? [英] Is mysqli extension enabled in this php configuration?

问题描述

我有一个用phpi设计的网站，扩展名为mysqli(改进mysql). phpinfo()页面显示以下内容:

I've a website designed in php with mysqli (mysql - improved) extension. The phpinfo() page shows this:

./configure --disable-fileinfo --disable-phar --enable-bcmath --enable-calendar --enable-ftp --enable-gd-native-ttf --enable-libxml --enable-magic -quotes --enable-mbstring --enable-pdo = shared --enable-soap --enable-sockets --enable-wddx --enable-zend-multibyte --enable-zip --prefix =/usr --with -bz2 --with-curl =/opt/curlssl/--with-curlwrappers --with-freetype-dir =/usr --with-gd --with-imap =/opt/php_with_imap_client/--with-imap- ssl =/usr --with-jpeg-dir =/usr --with-kerberos --with-libdir = lib64 --with-libexpat-dir =/usr --with-libxml-dir =/opt/xml2- with-libxml-dir =/opt/xml2/--with-mcrypt =/opt/libmcrypt/--with-mysql =/usr --with-mysql-sock =/var/lib/mysql/mysql.sock- with-mysqli =/usr/bin/mysql_config --with-openssl =/usr --with-openssl-dir =/usr --with-pcre-regex =/opt/pcre --with-pdo-mysql = shared- -with-pdo-sqlite = shared --with-pic --with-png-dir =/usr --with-pspell --with-sqlite = shared --with-tidy =/opt/tidy/--with- xmlrpc --with-xpm-dir =/usr --with-xsl =/opt/xslt/--with-zlib --with-zlib- dir =/usr

这是否意味着在此配置中启用了mysqli扩展?

Does this mean that mysqli extension is enabled in this configuration?

推荐答案

应该启用mysqli扩展名，然后在相同的phpinfo页面上使用" MysqlI支持|启用"表标题应该出现.寻找那个:

Should the mysqli extension be enabled then on the very same phpinfo page a "MysqlI Support | enabled" table header should appear. Look for that:

如果要在脚本中查找，请查找特定于mysqli的函数，例如 ，然后检查其是否存在:

If you want to find out in a script, look for a function specific for mysqli like mysqli_connect() and than check if it exists:

var_dump(function_exists('mysqli_connect'));

如果输出为FALSE，则说明它不存在，很可能无法使用该模块.

If this outputs FALSE, then it does not exists and it's highly likely that you can not use the module.
