Zend_Version
provides a class constant
Zend_Version::VERSION
that contains a string
identifying the version number of your Zend Framework installation.
Zend_Version::VERSION
might contain "1.7.4", for example.
The static method Zend_Version::compareVersion($version)
is based on the PHP function
version_compare()
.
This method returns -1 if the specified version
is older than the installed Zend Framework version, 0 if they are the same
and +1 if the specified version is newer than the
version of the Zend Framework installation.
Example 60.1. Example of the compareVersion() Method
// returns -1, 0 or 1 $cmp = Zend_Version::compareVersion('2.0.0');
