As you can see above, each page has the same header and bottom. As shown in the preceding figure, the same information can be written to each page when the workload is low, but imagine how much effort you will spend when there are more than 100 pages and you need to change all of their headers or bottoms? How tedious and boring is m

MongoDB update data syntaxIn the previous article "MongoDB query syntax", I introduced the common query syntax of MongoDB, and the update operation of MongoDB is a bit complicated. I will introduce it here based on my experience, let's take a look at MongoDB users. It is also convenient for future users to refer:

Since version 3.4.x and version 4.x, gnu cc also supports this mechanism to improve compilation efficiency. The reason is that the using precompiled headers section in the gnu cc Manual does not provide much information about this, and there is no simple automatic project management tool to support this function, therefore, many netizens do not know the gnu cc function.
In the gnu cc manual, we recommend that you use make to manage pre-compiled header fi

How tedious and boring is manual changes on one page! Therefore, we should write PHP headers and bottom files for these pages, and then we just need to reference them in each HTML page. The include and require functions contain a PHP code file. regardless of the file extension, the file is treated as a PHP fil

As your business continues to increase, orders will continue to increase, and a lot of disk visits are required to process each order. It is very likely that you will put all the orders in an accounting system one day.
Now, place the order in an independent database. Because the inventory is updated through the order, the inventory is a

You can use modifiers to modify a document, such as adding or deleting a document's key value. Using the modifier first to navigate to a document and then add the appropriate modification options, you need to use the UPDATE statement1.

the document will only have a part to be updated. Using an atomic update modifier makes this part of the update extremely efficient. The update modifier is a special key that specifies complex update operations, such as resizing, adding or removing keys, or manipulating arrays or inline documents.For example, to record website access, when someone accesses, you need to increase the counter, you can use the update modifier atomically to complete this increase:In PHP, $ represents a variable pref
