zend_eval_string in the previous article, some clever phper have thought of, right! The idea is to just find the eval and change it to echo.Practical examplesWe can't just dazoigu guns and say no. Here's an example:This time we'll take the php-beast of Pine brother. Pine's code was beautifully written, and it was known that AES DES decryption was time consuming and wrote a Cache.1.

Basic, Visual C ++, Delphi, and Power Builder. I often see some beginners asking: how can I learn C/C ++? is it better to learn Visual C ++ or Borland C ++ Builder? Alternatively, you must select between Visual Basic and Delphi. What is the relationship between learning programming and learning programming languages? How should beginners choose? In this case, let's make a simple analogy: Learning program design is like learning shooting, and the programming language corresponds to various firea
Webshell cleanup-driver-level file hiding on the server
Today, my friend's website is infected with Trojans. Baidu and Google search will find keywords such as guns and support. I have not found the cause for a long time, so I asked my younger brother to check the cause, in the end, I found that the server encountered driver-level file hiding, which I had never encountered before. record it and share it with friends in need.Symptom:Through Baidu and

So why does a FW do this? Ovear makes a no-responsibility speculation here. The most likely reason is that an FW employee originally wanted to block this IP segment, however, I accidentally entered the DNS pollution option, and did not write the pollution target, so the global pollution was caused ~
However, some children's shoes may ask why they say it's okay to use 8.8.8.8 ~
In fact, this is not correct, because Ovear used 8.8.8.8 before. The above also mentioned the default UDP q
to avoid UDP-contaminated map guns.
So why Will DNS be contaminated after the pollution ends? In fact, the reason is very simple. As Ovear mentioned earlier, [recursive DNS] requires querying [root DNS], while the default query method is UDP, naturally, it is polluted. Ovear mentioned TTL before ~
During the TTL period, [recursive DNS] based on the protocol directly caches the results on your own, and does not query [root DNS] any more, so the DNS in

citizens ran to Wu Dai under the microblog of Mr. Rong, a massive insult to abuse, leading Mr. Wu to close the comments.

To this end, Cologne a great God (non-Wu Dai fan) by the people of the well-being to a bird do not know what it is, just to show him Mr. Wu has filmed three l

We should use C to achieve the large framework of the program, and in line with the principle of good steel used in the cutting edge of the assembly, because only in a few special occasions are not used in assembly language, they are: Functions that cannot be written in C, such as manipulating special function registers, and implementing mutually exclusive access.Cheng (for example, NMI service routines) that perform processing at critical jun

people here. Code128 code has a first and a tail. The tail is always 2331112, which represents the end of Code128. The rest of the section is 6 bits for a block, including the head. There are 3 kinds of head: a) 211412 B) 211214 C) 211232. This indicates, respectively, what type this Code128 is.

lights, and subtractive methods, using pigments to reduce light waves. The color plate and CMYK system used by traditional artists are subtractive modes. On the website, we are faced with the projection of light, not the light reflected back from the object, so we use the additive mode, which we call RGB.
Add Color method
In nature, the light waves we see are reflected through objects into our retina, but the way in which color is produced is not only this one. For example, stage lighting use

How do we choose to use design patterns when we are developing the program? If it is a small program, I do not want to go too far toward the design pattern, there is a suspicion of excessive design.
