Accepted Answer

as @k102 mentioned `dl()` has been disabled by default since 5.3:

as refered on the php documentation: http://php.net/manual/en/function.dl.php

```
    5.3.0   dl() is now disabled in some SAPIs due to stability issues.
The only SAPIs that allow dl() are CLI and Embed. Use the Extension Loading Directives instead.
```

as suggested there, use the Extension Loading Directives instead: http://www.php.net/manual/en/ini.core.php#ini.extension

Basically your only choices are:

- Load the extension configuring it properly on the php.ini

- Use one of the mentioned SAPI's that still supports `dl()` as mentioned in the documentation: (CLI, CGI and Embed)

- Downgrade your php version if you really need to load it dinamically
