Fatal error: Class 'SoapClient' not found - php

Question

I'm trying a simple web service example and I get this error even though I uncommented extension=php_soap.dll in the php.ini file:
Fatal error: Class 'SoapClient' not found in C:\Program Files (x86)\EasyPHP-5.3.9\www\server.php on line 2

Answer 1

Diagnose
Look up the following inside your script file
phpinfo();
If you can't find Soap Client set to enabled like so:
Fix
Do the following:
Locate php.ini in your apache bin folder, I.e Apache/bin/php.ini
Remove the ; from the beginning of extension=php_soap.dll
Restart your Apache server
Look up your phpinfo(); again and check if you see a similar picture to the one above
If you do, problem solved!
On the other hand if this doesn't solve your issue, you may want to check the requirements for SOAP here. Also in the comment section you can find good advice on connecting to https.

as root and restart apache.
That worked! Now my phpinfo() call shows the SOAP section.

I couln't find the SOAP section in phpinfo() so I had to install it.
For information the SOAP extension requires the libxml PHP extension. This means that passing in --enable-libxml is also required according to http://php.net/manual/en/soap.requirements.php
