SAMPLES

Run the following PHP command from within your installation directory to install the samples

php install.php

At the prompt for your target web directory, enter the name of the directory where you wish to install the SDK samples (eg. /usr/local/apache/htdocs/php-sdk). If your application is on a shared server, enter the full path to a subdirectory of your public HTML directory into which the installer will copy the SDK sample files. The directory should not previously exist on your server.

If you see no error messages, the installation was successful. To verify installation, browse to the installation directory and you should see the paypal_php_samples directory

To run the samples:

Go to

http://www.mydomain.com/<targetDir>/paypal_php_samples/index.php

Providing Proxy Support

Right now, if the user is behind proxy,unable to make a API call to PayPal.

"SDKProxyProperties.php"(<installation directory>/php-sdk/lib/PayPal/) is the configuration file for Proxy setup.

Update the following variables in "SDKProxyProperties.php" for Proxy configuration.

USE_PROXY - Set this variable to TRUE to route all the API requests through Proxy(by default it is FALSE).
PROXY_HOST - Set this variable to Proxy Server name or IP address
PROXY_PORT - Set this variable to Proxy Server port
PROXY_USER - Set this variable to Proxy Server user id (optional)
PROXY_PASSWORD - Set this variable to Proxy Server password (optional)

NOTE:

Since PHP does not support "-" in variable names,sdk WSDL proxy generator will replace it by "_".
Before sending the xml request string, "_" has to be replaced by "-" back and this will be done by '/PayPal/SOAP/PatternReplace.php' which is called in '/PayPal/SOAP/client.php'. Uncomment the line in client.php if any wsdl tag element with "-" is in use(like "cpp_header_image")
