Is mysqli extension enabled in this php configuration?
提问by arun nair
I've a website designed in php with mysqli (mysql - improved) extension. The phpinfo() page shows this:
我有一个用 php 设计的网站，带有 mysqli（mysql - 改进）扩展。phpinfo() 页面显示：

Does this mean that mysqli extension is enabled in this configuration?
这是否意味着在此配置中启用了 mysqli 扩展？
回答by mario
Should the mysqliextension be enabled then on the very same phpinfopage a "MysqlI Support | enabled" table header should appear. Look for that:
如果mysqli扩展被启用，那么在同一个phpinfo页面上应该会出现一个“ MysqlI Support | enabled”表头。寻找那个：
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:
如果您想在脚本中查找，请查找特定于 mysqli 的函数，mysqli_connect()然后检查它是否存在：
var_dump(function_exists('mysqli_connect'));
If this outputs FALSE, then it does not exists and it's highly likely that you can not use the module.
如果输出 FALSE，则它不存在，并且您很可能无法使用该模块。
回答by John Cartwright
It means it was compiled with mysqli support. Whether the module is enabled or not is another question.
这意味着它是用 mysqli 支持编译的。是否启用模块是另一个问题。
