Troubleshooting SoapClient Not Showing in PHPInfo (PHP 7.1.9)

Hey there, I’ve dealt with this exact head-scratcher before—let’s walk through the steps to get your Soap extension showing up in phpinfo():

Double-check you’re editing the RIGHT php.ini file
Systems often have multiple php.ini copies (one for CLI, one for Apache). First, open up your phpinfo() page and look for the Loaded Configuration File line—this is the exact file Apache is using. It’s super common to edit the wrong one by mistake, so confirm your changes were made here, not a random php.ini in another directory.
Install the CORRECT version of the Soap package
You ran sudo apt-get install php7.0-soap, but your PHP version is 7.1.9—this mismatch is probably the root issue! Install the version that matches your PHP:
```
sudo apt-get install php7.1-soap
```
Then restart Apache to apply the change:
```
sudo systemctl restart apache2
# Or use this if systemctl isn't available on your distro:
# sudo service apache2 restart
```
Verify extension loading outside phpinfo()
Create a quick test file (e.g., test_soap.php) with this code:
```
<?php
var_dump(class_exists('SoapClient'));
?>
```
Access it through your browser. If it returns bool(true), the extension is working even if phpinfo() hasn’t updated (unlikely, but possible). If it returns bool(false), the extension isn’t loading at all—move to the next check.
Check Apache’s PHP extension config directory
On Debian/Ubuntu systems, PHP extensions often load via separate .ini files in /etc/php/7.1/apache2/conf.d/. Look for a file named something like 20-soap.ini—it should contain the line:
```
extension=soap.so
```
If the file doesn’t exist, create it with that line, then restart Apache again.
Dig into error logs for clues
If nothing else works, check Apache’s error log (usually at /var/log/apache2/error.log) and PHP’s error log. Look for lines mentioning "soap" or "extension loading failure"—these will tell you exactly why the extension isn’t loading (e.g., missing .so file, permission issues, etc.).
