How to install PHP extension under IIS (super simple)

This article mainly introduces the method of installing PHP extension under IIS. It is very simple and has reference value. Friends in need can refer to it

Many online articles introduce the installation of PHP under IIS It will involve a lot of configuration modifications. In fact, most of them are unnecessary. For people who need to find out how to install PHP extensions, what they need most is probably a version that can be used now. Too many configurations are introduced at this time. Unnecessary configuration I think is inefficient.

So to summarize, the installation steps only require three steps:

1. Download the PHP file package;

2. Configure PHP;

3. Introduce PHP extensions into IIS;

Of course, there may be step 4: testing.

Step 1: Download PHP

The Windows version of PHP directly provides a compressed package, which includes everything needed for operation. The file can be called a fool-proof installation. It can be obtained from the windows download area on the official website (http://windows.php.net/download). Please note that there are three points to pay attention to when selecting the version:

1. Select PHP Versions are mainly divided into PHP5. If there are specific framework or project requirements, just refer to the document to select the version.

2. Select the processor architecture, mainly refers to X86 and , just choose this version.

3. Select the thread-safe version. You can choose this according to your needs. Relatively speaking, ThreadSafe will have some efficiency losses due to the need to take into account thread safety, but the loss is not significant; if you are using FastCGI, you can directly choose Non-ThreadSafe.

In short, if you have no special needs, I recommend that you choose PHP7.X X64 Non-ThreadSafe (PHP7, 64-bit architecture, non-thread-safe version).

Step 2: Configure PHP

First select a directory to decompress. It is recommended to create a folder in the root directory of the hard disk you use for programming. , extract all the files in it. This is because future PHP requests will make requests to the CGI program in this designated location, and it is best not to change frequently.

Then add this directory ("E:\PHP" in this article) to the Path constant (right-click "My Computer" => Properties => Advanced System Settings=>Environment Variables in the lower right corner of the Advanced tab=>System Variables=>Path), be sure to add a ";" semicolon for separation before adding. After adding to the Path variable, you can use the content in the PHP folder without entering the full path, just type the file name directly (for details, you can search the retrieval sequence of the Windows command line).

Then make a copy of the "php.ini-development" file and rename the copy to "php.ini". Here is the PHP configuration officially recommended by PHP for development. For beginners, we No modifications are required; if your target framework or project requires it, make changes as required (such as requiring specified extensions, etc.).

At this point, the PHP configuration is completed.

Step 3: Introduce IIS

First open the IIS management tool and select "Process Application Mapping".

Select "Add Module Mapping" in the new interface

##Fill in the information as follows:

The first line represents which files will be handed over to PHP for processing. Filling in *.php means that all files with PHP extension will be handed over to php-cgi for processing.

The second line represents the type of mapping of this module. If there are no special requirements, we choose FastCGI.

The third line represents the location of the processing module. Enter our PHP decompression directory and select php-cgi.exe.

The name is just for identification and can be filled in at will.

After clicking OK, you will be asked whether to automatically add the allow rule, just confirm.

This completes the installation of PHP extension for IIS.

Step 4: Test

Create a new test.php file in the default website directory and fill in

<?php
phpinfo();
?>

Then open the browser and access localhost\test.php. If the following information is displayed, the installation is successful.
