Posted @ Jacob. Xu read (10) Comments (0) EDIT Bootstrap

Bootstrap, as its name implies, is to tie the shoelaces and point out the preparations made before sending. Since Zend framework 1.8 and later, Zend framework has released zend_tool and zend_application. Therefore, bootstrap has made great adjustments. Basically, you only need to set the value in index. when zend_application is called in PHP, you can directly set the config file, DB, view, and so on. If you need to make special settings, you can extend zend_application_bootstrap_bootstrap in Bootstrap and use the _ init * Resource function to set the settings. Bootstrap will call these _ init * resource functions one by one in order, then execute dispatch. Note the following points:

1. Do not mark the response attribute during initview, so that this Bootstrap will not instantiate response before layout;

2. You can determine the Ajax request header to remove layout, viewrender, errorhandler, and exception output. This frees you from setting it on the Ajax page.

3. After zf1.8, you can set the driver option to lazy load the DB charset of ZF.
