"Class 'SoapClient' not found" Error: Debugging and Resolution

Trying to establish a web service connection can be met with the frustrating error "Fatal error: Class 'SoapClient' not found." This error message can arise even after enabling the SOAP extension in php.ini. To effectively address this issue, let's dive into the diagnostic process.

Diagnosis

To begin, locate your script file and include the following line of code:

phpinfo();

Execute your script, and in the resulting phpinfo() output, look for the "Soap Client" entry. If it is not listed as enabled, the SOAP extension may not have been properly configured.

Fix

To rectify this issue:

1. Navigate to the php.ini file located in your Apache bin folder (typically at Apache/bin/php.ini).
2. Locate the line "extension=php_soap.dll" and remove the preceding semicolon (;).
3. Restart your Apache server.
4. Re-run the phpinfo(); script and verify that the "Soap Client" entry is now enabled.

If this method does not resolve the issue, consider checking the system requirements for SOAP support and consulting the comment section for potential solutions related to HTTPS connectivity.
