This extension offers a PHP interface to the YAZ toolkit that implements the Z39.50 protocol for information retrieval.
It supports persistent stateless connections very similar to those offered by the various SQL APIs that are available for PHP.
Compile YAZ and install it.
Build PHP with your favourite modules and add option --with-yaz.
gunzip -c yaz-1.6.tar.gz| tar xf - gunzip -c php-4.0.X.tar.gz |tar xf - cd yaz-1.6. / configure --prefix= / usr make make install cd.. / php-4.0.X. / configure --with-yaz= / usr / bin make make install
