# Getting the Zend Framework Version

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 #1 Example of the compareVersion() Method

1. // returns -1, 0 or 1
2. $cmp = Zend_Version::compareVersion('2.0.0');
