First of all, I would like to apologize for the remarks I made about PHP version in my blog before. In any case, because of my personal common sense mistakes, it caused a bad impact and misled some people. Audiences who don’t know the truth~
Next, I will explain here about the PHP version (all previous remarks involving the PHP version, if there is any conflict, this time shall prevail. ).
PHP version is mainly divided into three branches: PHP4/PHP5/PHP6
Since PHP4 has been eliminated long ago, and PHP6 is too forward-looking and currently has no products, so we are currently All used are PHP5 series.
We also divide PHP5 into three branches: before PHP5.2/PHP5.2.X/PHP5.3.X
Similarly, the version before PHP5.2 has some defects and BUGs. There is no market; and PHP5.2.X is currently the most stable version, with excellent compatibility and security; and PHP5.3. At the same time, the system usage is better.
After talking for a long time, I didn’t get to the point. Why do you say it is a common sense mistake?
A few days ago, I once said that since the upcoming WordPress 3.2 requires PHP version 5.2.4 or above, and the PHP version of my space is 5.2.17, it needs to be upgraded, and I actually upgraded it. , upgraded to the latest 5.3.6.
Now, I solemnly overturn the above remarks! Version 5.2.17 is higher than 5.2.4, which is very depressing. The 17 in the PHP version is more appropriately pronounced as "seventeen". The arrangement of this version is also strange. The last section is not equivalent to the number we often use, so This made me upgrade blindly without any verification! Although upgrading is beneficial and harmless, the reason is absurd and shameful.
The picture above shows the two PHP versions currently provided on the PHP official download page.
