Composer setup installation error

Question

I'm trying to install Composer on Windows 7 and XAMPP, but getting those errors/messages when run installation setup.

The PHP exe file you specified did not run correctly: C:\xampp\php\php.exe

The php.ini used by your command-line PHP is: C:\xampp\php\php.ini

A duplicate setting in your php.ini could be causing the problem.

Program Output: Warning: Module 'openssl' already loaded in Unknown on line 0

I have been googled for while, but could not find proper solution or anything related to this. Closest thing was to remove comment openssl extension in php.ini file, but did not worked for me. To be clear I have very basic understanding of server tweaking.

Solution 1

OpenSSL is being loaded twice. Look in your php.ini above to see openssl.dll, and comment it out in one of the places.

Solution 2

I guess this is a problem which had been asked here you can follow the solution or go to the below link whichever if you want.

I figured it out and successfully installed Composer in My windows 10 PC.

There are some steps you have to follow in order to solve your problem.

1st solution.

1. Find and Open php.ini located in your "php" folder In my case it is in xampp the file is in c:\xampp\php\
2. Find "extension=php_openssl.dll"
3. ";extension=php_openssl.dll" uncomment by removing the semicolon ";"
4. Restart your xampp , now extension should be loaded after that.
5. Try again now you are able to install composer.

2nd solution(If the above solution not work for you then go with below solution . )

This works in my case

1. Find and Open php.ini located in your "php" folder In my case it is in xampp the file is in c:\xampp\php\

2. Open SHELL from Xampp start panel by clicking on shell button.

3. Write php in shell and hit enter

4. If you get some waring message in your shell something like below .

5. Then you have to fix these waring message by commenting all these extension in your php.ini file.(Actually cause of these warning messages are because more than one times that extension are enabled or you can say un-commented in php.ini file).

   For Example which is in my case.

   a). You can see in above image there is warning message for curl.

   Module 'curl' already loaded in Unknown on line 0 .
   

   b) To fix this find php_curl.dll file in your php.ini file and comment that extension by adding semicolon ";" in front of that extension like this ;extension=php_curl.dll

Follow above steps if you have more than one warning for each extension untill you are not getting any warning message in your shell.

6. Restart your xampp , now extension should be loaded after that.
7. Try again now you are able to install composer.

Solution 3

1. Go to your xampp\php\php.ini
2. Press ctrl+f to find extension_dir and change its relative path to absolute path e.g from extension_dir="\ext" to extension_dir="E:\xampp\php\ext"
3. Press ctrl+f to find browscap and change its path e.g from
   browscap="\xampp\php\extras\browscap.ini" to
   browscap="E:\xampp\php\extras\browscap.ini"
4. Save the file and restart the xampp

try again with the composer installer
