The quick documentation of php built-in functions is in English, as follows
But I don't know what configuration changes have caused everything to become Chinese when I recently used it (it is good to say that it is changed to Chinese, but some translations of tm are not smooth) as follows
In the end, I found the configuration after trying my own. The reason is that the new version of the translation plugin has a document translation function and is turned on by default. The method of closing is as follows: Open the phpstorm configuration box, find the translation plugin configuration, and translate the document before Tick to remove the final save. (The following picture is the path on the mac, the configuration of the window seems to be called setting. At the same time, the configuration path of different versions of the idea may be slightly different but the difference is very small, and you can find it roughly if you look for it)
