~/public_html/php-5.3.13/ext> tar zxvf vld-0.11.2.tgz
~/public_html/php-5.3.13/ext> cd vld-0.11.2/
Next compile and install the vld extension:
~/public_html/php-5.3.13/ext/vld-0.11.2> phpize
~/public_html/php-5.3.13/ext/vld-0.11.2> ./configure --with-php-config=/usr/local/services/php/bin/php-config --enable- vld
~/public_html/php-5.3.13/ext/vld-0.11.2> make
~/public_html/php-5.3.13/ext/vld-0.11.2> sudo make install
Installing shared extensions: /usr/local/services/php/lib/php/extensions/no-debug-non-zts-20090626/
Finally copy the generated vld.so to the extension_dir directory:
~/public_html/php-5.3.13/ext/vld-0.11.2> cd /usr/local/services/php/lib/php/extensions/no-debug-non-zts-20090626/
/usr/local/services/php/lib/php/extensions/no-debug-non-zts-20090626> sudo cp vld.so /usr/local/services/php/extensions/
Then modify the php.ini file and add the following configuration:
extension=vld.so
Next create the test.php file:
$a = "hello world";
echo $a . PHP_EOL;
Use cli to execute and view the generated opcode:
~/public_html> php -dvld.active=1 test.php
