Here is PHP examples

- libusb-1.0 >= 1.0.16
There are two ways to modify an extension created using CodeGen_PECL:
-
you can modify the generated code as with any other PHP extension
-
you can add custom code to the CodeGen_PECL XML source and re-run pecl-gen
The 2nd approach may look a bit complicated but you have be aware that any manual changes to the generated code will be lost if you ever change the XML specs and re-run PECL-Gen. All changes done before have to be applied to the newly generated code again. Adding code snippets to the XML source itself on the other hand may be a bit more complicated but this way your custom code will always be in the generated code no matter how often you rerun CodeGen_PECL.
This extension depends on libusb-1.0. Please make sure that libusb-1.0 has installed.
To compile your new extension, you will have to execute the following steps:
./phpize
./configure
make
make test
[sudo] make install
You can now load the extension using a php.ini directive
extension="usb.[so|dll]"
or load it at runtime using the dl() function
dl("usb.[so|dll]");
The extension should now be available, you can test this using the extension_loaded() function:
if (extension_loaded("usb")) echo "usb loaded :)"; else echo "something is wrong :(";
The extension will also add its own block to the output of phpinfo();
