Question

我的php.ini扩展部分如下所示

    ; Windows Extensions
; Note that ODBC support is built in, so no dll is needed for it.
; Note that many DLL files are located in the extensions/ (PHP 4) ext/ (PHP 5+)
; extension folders as well as the separate PECL DLL download (PHP 5+).
; Be sure to appropriately set the extension_dir directive.
;
;extension=php_bz2.dll
;extension=php_curl.dll
;extension=php_fileinfo.dll
;extension=php_gd2.dll
;extension=php_gettext.dll
;extension=php_gmp.dll
;extension=php_intl.dll
;extension=php_imap.dll
;extension=php_interbase.dll
;extension=php_ldap.dll
;extension=php_mbstring.dll
;extension=php_exif.dll      ; Must be after mbstring as it depends on it

;extension=php_soap.dll
;extension=php_sockets.dll
;extension=php_sqlite3.dll
;extension=php_tidy.dll
;extension=php_xmlrpc.dll

我正在使用PhpStorm来托管PHP。每当我尝试运行该功能时，我都会得到这个：

Fatal error: Uncaught Error: Call to undefined function mysqli_connect() in **archive** Stack trace: #0 {main} thrown in **archive**

我的代码如下：

<?php
$con = mysqli_connect("localhost","root","","aula") or die(mysqli_error($con));
mysqli_query($con, 'SET NAMES utf8') or die(mysqli_error($con));

在第二行我已经收到错误。如何安装扩展程序？提前谢谢。

Answer 1

请确保在... // same code byte[] outPdfBuffer = htmlToPdfConverter.ConvertUrl(url); MemoryStream stream = new MemoryStream(outPdfBuffer); Document document = new Document(stream); document.LicenseKey = "myKey"; document.OpenAction.Action = new PdfActionJavaScript("print()"); byte[] b = document.Save(); Stream strm = new MemoryStream(b); Response.AppendHeader("content-disposition", "inline; filename=file.pdf"); return new FileStreamResult(strm, "application/pdf");中取消注释extension=php_mysql.dll和extension=php_mysqli.dll，php.in是“改进的”MySQL库，但这并不一定意味着它取代了{{ 1}}完全。

另外请确保设置正确的php PATH环境变量。

Answer 2

从

改变

extension_dir =“ext”

到

extension_dir =“C：\ Apache24 \ php \ ext”

Answer 3

（在Windows上工作）

我面临着同样的问题。

就我而言，问题是我将php.ini文件保存为文本文件。只要我将文本文件转换为＆＃34;所有文件＆＃34;在记事本中给了它＆＃34; .ini＆＃34;扩展，它成为＆＃34;配置设置文件＆＃34;它起作用了。

您可以通过浏览phpinfo（）中已加载的配置文件行来检查是否是这种情况。如果值为“无”，则可能会遇到类似问题。

注意：我已经取消注释扩展并修复了扩展目录。
