111 Your server doesn't have support for PHP 5. |
|
112 </h2> |
|
113 <p> |
|
114 PHP 5 is the latest version of the language on which Enano was built. Its many new features have been available since early 2004, yet |
|
115 many web hosts have not migrated to it because of the work involved. In 2007, Zend Corporation announced that support for the aging |
|
116 PHP 4.x would be discontinued at the end of the year. An initiative called <a href="http://gophp5.org/">GoPHP5</a> was started to |
|
117 encourage web hosts to migrate to PHP 5. |
|
118 </p> |
|
119 <p> |
|
120 Because of the industry's decision to not support PHP 4 any longer, the Enano team decided that it was time to begin using the powerful |
|
121 features of PHP 5 at the expense of PHP 4 compatibility. Therefore, this version of Enano cannot be installed on your server until it |
|
122 is upgraded to at least PHP 5.0.0, and preferably the latest available version. |
|
123 <!-- No, not even removing the check in this installer script will help. As soon as the PHP4 check is passed, the installer shows the |
|
124 language selection page, after which the language code is loaded. The language code and libjson2 will trigger parse errors under |
|
125 PHP <5.0.0. --> |
|
126 </p> |
|
127 <p> |
|
128 If you need to use Enano but can't upgrade your PHP because you're on a shared or reseller hosting service, you can use the |
|
129 <a href="http://enanocms.org/download?series=1.0">1.0.x series of Enano</a> on your site. While the Enano team attempts to make this |
|
130 older series work on PHP 4, official support is not provided for installations of Enano on PHP 4. |
