It is possible that WAMP and Composer are using different PHP installations. Composer will use the PHP set in the <code>PATH</code> environment variable. 

If you want to enable the openssl extension to install Composer, first you need to check the location of the PHP installation.

<ol>
<li>Open a Command Prompt, type: <code>echo %PATH%</code> then check for the location of your PHP installation.</li>
<li>Go to that location and edit the file named: <code>php.ini</code>.</li>
<li>Uncomment the line <code>extension=php_openssl.dll</code> by removing the semicolon at the beginning.</li>
</ol>

Now you are good to install Composer.

I solved my problem a different way. The problem is that wamp's GUI was misleading: it claimed that I had <code>php_openssl</code> enabled.. and if I clicked on <code>php.ini</code> on the same GUI.. it actually showed that <code>extension=php_openssl.dll</code> was uncommented.. 

I'm not sure if i'm using the same installer version of composer of the OP, but it actually asks you at the beginning to specify the <code>php.exe</code> that you like to apply composer on (which basically ensures that no one tries to apply composer to the wrong php executable as what happened with the OP)..

The way I solved this was by going myself into the installation of php within the wamp package: <code>C:\wamp\bin\php\php5.4.12</code> and looking <code>php.in</code> there.. when I opened it I was shocked that the line <code>extension=php_openssl.dll</code> was actually commented! I uncommented it and it worked just fine.

I had the same problem and here the solution I found, on your php.ini you need to do some changes:

<ol>
<li><code>extension_dir = "ext"</code></li>
<li><code>extension = php_openssl.dll</code></li>
</ol>

Every one here talks active the openssl extension, but in windows you need to active the extension dir too.

For WAMP server, comment given by "Enrique" solved my problem.

wamp is using this php.ini:

<pre><code>c:\wamp\bin\apache\Apache2.4.4\bin\php.ini
</code></pre>

But composer is using PHP from CLI, and hence it's reading this file:

<pre><code>c:\wamp\bin\php\php5.4.12\php.ini (so you need to enable openssl there)
</code></pre>

For composer you will have to enable extension in

<pre><code>c:\wamp\bin\php\php5.4.12\php.ini
</code></pre>

Change:

<pre><code>;extension=php_openssl.dll 
</code></pre>

to

<pre><code>extension=php_openssl.dll
</code></pre>

If you're doing this on Windows without one of the WAMP stacks, here's how to get this going

<ol>
<li>Download an <a href="http://windows.php.net/download/" rel="noreferrer">installation of PHP for Windows</a>. Generally you'll want a non-thread safe install. You can use 32-bit or 64-bit builds</li>
<li>Extract the zip file somewhere. I would suggest <code>C:\php</code>. Composer's installer found it there without any additional prompting</li>
<li>The latest versions of PHP for Windows do not come with a <code>php.ini</code> by default. Instead, you'll see two files, as noted below. Rename one to <code>php.ini</code> or copy it into <code>php.ini</code>.

<ul>
<li>php.ini-development</li>
<li>php.ini-production</li>
</ul></li>
<li>Open your <code>php.ini</code> file and remove the semicolon from this line (you might want to uncomment other things as well but this line is the only one necessary for Composer)

<pre><code>;extension=php_openssl.dll
</code></pre></li>
</ol>

That should be all you need to do. The Composer installer should do everything else you need from here.

But manually I went to the folder and edited <code>php.ini</code>.
Then I found it has not opened openssl.I uncommented it and it worked after after WAMP restart.

If you still cannot solve your problem have a look at this. This might be the solution you are looking for

There are several php.ini files in C:\wamp\bin\php\php x-y-z folder. You may find production, development and some other php.ini files. No point of editing production and development files. Find the file which is exactly as same as the below image. (You can find it. Just type php.ini in your search bar and do a search). Open the file and remove ; from extension=php_openssl.dll. Save the file and close it. Restart all services in Wampp server. Re-install your composer. 

That is it.

blocks|key|182796|text|Wamp可以与C:\wamp\bin\apache\Apache2.4.4\bin\php.ini中的另一个php.ini一起工作。所以你需要手动找到正确的文件，也就是C:\wamp\bin\php\php5.4.12\php.ini。取消注释extension=php_openssl.dll行，然后再次尝试安装Composer。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|182797|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Wamp works with another php.ini that is in C:\wamp\bin\apache\Apache2.4.4\bin\php.ini. So you need to manualy find the correct file, that is in C:\wamp\bin\php\php5.4.12\php.ini. Uncomment the extension=php_openssl.dll line and just try to install Composer again.

blocks|key|2792241|text|对于那些和我有同样问题的人。在做了上面所有的解决方案后，仍然对我不起作用。我发现，uWamp在bin/apache目录中创建了PHP.INI文件。因此，我必须将PHP.INI文件复制到php安装目录，即bin/php/phpXXXX目录。这也应该是您从composer设置中选择的php.exe所在的位置。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2792242|希望这能有所帮助。|2792243|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

For those who're having the same problem as I was. After doing all the solutions above, still didn't work for me. I found out that, uWamp was creating the PHP.INI file in bin/apache directory. So I had to copy the PHP.INI file into php installation directory, that is, bin/php/phpXXXX directory. This should also be where the php.exe is that you selected from the composer setup.

Hope this helps.

If you compiled from source, then adding <code>extension=php_openssl.dll</code> to the php.ini file may not work.

To troubleshoot this, open a command prompt and type <code>php -i</code>. Scroll up to the first line, it will tell you the most recent error regarding your php.ini file.

To solve the issue, find the <code>php_openssl.dll</code> file, for me it was in the very same directory of the compilation output: 
<code>C:\php-sdk\bin\phpdev\vc14\x64\php-7.0.13-src\x64\Release_TS</code>
So just add the directory where the extension is, to the <code>php.ini</code>:

<pre><code>extension_dir = "C:\php-sdk\bin\phpdev\vc14\x64\php-7.0.13-src\x64\Release_TS"
</code></pre>

Hopefully the error will be gone

If you are using xampp .Go back to where you choose which command-line php you want to use at the beginning of your installation and select the path where your xampp folder is included.After that if your installer says youve got duplicate 'extension=php_openssl.dll' comment one ssl file in your php ini with a ';'and your installation should run smoothly.

I am trying to install Laravel in WAMP setup. I am getting a warning message for not enabling openssl which I had already done in WAMP.

Here is a screenshot of the message.
