Zend OPcache
Bytecode caching technology is not new to PHP. We already have Alternative PHP Cache (APC), eAccelerator, ionCube, and XCache independent Extensions. they can all be used as our optional solutions. But they are not found in every core release version of PHP. Until now, PHP 5.5.0 has its built-in bytecode cache: Zend OPcache.
First, let me

driver dependencies between events and to manage the scheduling between tasks. Topological ordering is the sorting of the vertices of the DAG so that you (in the sort record) have a U (in the sorted records) that appears first for each directed Edge (U, v). It is also understood that V can only occur if all the source points of V are present at a point v.Gives the topological ordering of a forward-free graph:DfsIn Dfs, the vertices that are traversed are printed sequentially, and the vertices m

Each time PostgreSQL transitions from file-based replay to stream-based replay, you are facing a heavy starting point. In fact, starting a stream copy again is considered to be a boot point.Once the start point arrives, you can have PostgreSQL perform some cleanup (or anything else). It is easy to clean out old xlog or trigger some notifications.The following script shows how you can clean up any xlog of the d

Although PHP provides a skip escape sequence () for the newline character in a string, it also gives you a good idea to include a newline character in the string, PHP can also handle this form. When an HTML string is created, a line break symbol in the string is displayed.
Although PHP provides a skip escape sequence for line breaks (
), But it is good to let you know that it is good to include line breaks in the string literally. PHP can also handle this form. This is very convenient when c

Template practice
In a sense, a template is a structure between a macro and a general declaration.

We can organize templates in several waysSource code, The most common is to include the model.
There are three ways to organize a model:

Chapter 6 describes the structure. It provides a method for programmers to construct their own complex types by combining existing basic types.There are not many operations supported by the structure, including copying and assigning values, obtaining addresses, and accessing members. For copying and assigning values, you can assign values to a single member of a struct, or assign values to the entire Member
