Question:
How can I check whether or not Zend Optimizer is installed, and which version it is?
Answer:
Create a zendcheck.php file with the following code in it:
<?php
if ( ! function_exists('zend_optimizer_version'))
{
echo 'Install Zend Optimizer';
}
else
{
echo 'Zend Optimizer version: '.zend_optimizer_version();
}
?>
FTP the zendcheck.php file to your server, and open in your browser.
If Zend Optimizer has been installed correctly, it is also mentioned in the output of phpinfo().
