PHP download files automatically add BOM header, first need everyone to find out, what is the BOM header? When you save a text file in UTF-8 format with a program like Notepad under Windows, Notepad adds a few invisible characters (the EF BB BF) to the front of the file, which is the so-called BOM (Byte Mark).
In the Utf-8 encoded file BOM in the file head, occupies three bytes, used to indicate that the file belongs to the Utf-8 code, now has a lot of software to identify the BOM header, but s

The deque bidirectional queue is a continuous linear space with bidirectional openings that can efficiently insert and delete elements at both ends of the deque, which are very similar to vectors on the interface, and list the common member functions of deque:
The implementation of the deque is complex, and a map is maintained internally (note.) Not a map container in STL is a small contiguous space in which each element is a pointer to another (la
indicates that the surface of the image element is convex upward. A negative curvature indicates that the surface openings of the pixels are concave upward. A value of 0 indicates that the surface is flat.
The output curvature types available for selection are: section curvature (slope along the maximum slope) and plane curvature (perpendicular to the direction of the maximum gradient).
From the point of view of application, the output of the tool ca

First figure out, what is BOM header? When you save a text file in UTF-8 format with a program like Notepad under Windows, Notepad adds a few invisible characters (the EF BB BF) to the front of the file, which is the so-called BOM (Byte Mark).Not limited to Notepad saved files, as long as the openings in the file contain the EF BB BF several invisible characters (16 should be xefxbbxbf, visible with binary editing files).

quality of the program also plays an important role. Today's top PC programs like Fritz and Junior can reach and handle 500,000 scenarios per second. They are, in fact, more than 2600 points away and can counter anyone but the world's top 100 players. In the fast chess War human only about the top more than 10 can be competent, but in the ultra fast chess probably only 两、三名 human chess player to pass through.

In the design of the mobile end product, whether an application is friendly enough depends not only on whether its own function is good enough for the user, but also on whether the application is friendly to other applications and whether they will collide when the user calls the application to complete other applications.
