Echo lzf_optimized_for (), PHP_EOL

/ / 1

/ / returns 1 if LZF is optimized for speed, and 0 for compression.

All LZF provides are these three very simple functions. Lzf_compress () is used to compress and encode the string, and you can see that the compressed content of our output has become garbled. However, compared with the encoded content that Bzip2 does not understand at all, LZF can see part of the original text. Lzf_decompress () is used to decode the contents of the encoded string. Lzf_optimized_for () outputs the compiled running state of the LZF extension. If 1 is returned, it is optimized for the speed of the current system. If 0 is returned, it is only compressed.

Chinese support $str = "nowadays we webmasters choose more and more servers instead of virtual hosts. But after selecting a server, most of our netizens will directly use the pagoda panel, LNMP and other key to install WEB system to configure the website environment. Some software is indeed constantly upgraded and maintained and the security features are done well, but some may not take security into account.

Because most software providers pay more attention to features, they do not do enough for the security details. For example, some time ago, due to the loopholes in the THINKPHP framework, the programs installing THINKPHP were hacked, and at the same time, other websites in the same server were also hacked, so security issues still need to be dealt with separately. "
