fgets function. it can strip PHP and HTML tags and pass a third parameter to filter unnecessary data, which improves website security, for example, the message book can filter user input data. the fgetss function prototype is as follows:
The code is as follows:
String fgetss (resource fp, int length, string [optional] allowable_tags)
Allowable_tags.txt is optional. In this example, a line of text containing the html, body, and h1 mark is written in the leapsoulcn.txt file. Then, in the code

the third parameter to filter unnecessary data, can improve the security of the site, such as the message can filter the user's input data, the FGETSS function prototype is as follows:
String Fgetss (Resource fp,int length, string[optional] allowable_tags)
The allowable_tags parameter is optional, in which I have previously written a line of text containing HTML, body, H1 tags in the leapsoulcn.txt file, and then in the code I set only allow H1 tags to appear.

The fgetss function is a variant of the fgets function. It can strip PHP and HTML tags and pass a third parameter to filter unnecessary data, which improves website security, for example, the message book can filter user input data. The fgetss function prototype is as follows:

Hardware configuration management includes the model and hardware configuration of each server in the enclosure, and it is clear which business systems are using these servers. Even in virtualized environments, you need to know which physical machines are flowing in the pool of resources that these VMs are mad
In the MathType mathematical formula editor, the formula number has five parts: the chapter number (Chapter numbers), the section number, the formula number (equation numbers), the parentheses (enclosure), Delimiter (Separator). These five parts can be switched freely to achieve different needs. This article takes Microsoft Office as an example to teach you how to Modify chapter numbers in the MathType add-in in Word.How to set the formula number:1. C

, etc. in a page design can better differentiate between modules and content. As in (Fig. 4), Yahoo reading navigation, through the principle of similarity we can easily distinguish between level navigation and level two navigation.Figure 4To think differently, the change of color clearly distinguishes the different content, and the inverse thinking in similarity is a good way to get the focus. This method has been widely used in the design of navigation and emphasis on some information , 5.Figu

The system originally has n empty space, when you define a reference variable, you will find a similar size but may not be exactly the same space to store the address to the stack, and that space to save the specific values, but also to remove the extra parts to form a new space.

caller.These two problems DLL can not be solved very well, can only be said to be used. But in COM, all of them have been solved perfectly. So, whether you want to implement language independence on the Windows platform or only use COM middleware.In summary, DLLs are not easy to support C + + features such as function overloading, classes, unless the client also uses C + +. DLL's support for C functions is good, and I think that's one of the reasons why Windows libraries use C plus DLLs.Writing
simultaneously, but each other is set to standby, when one server fails, another server can in a short period of time to take over the application of the failed server, so as to ensure the continuity of the application, but the performance requirements of the server is relatively high. The server configuration is relatively better.dual-Machine Duplex modeAt present, a form of cluster (cluster), active/active Two servers are active, while running the same application, to ensure the overall perfo
