bom meaning

Recently there are many on the micro-blog to discuss the BOM head problem, BOM header will cause the page display garbled, XML analysis problems. And I happen to encounter a situation in the WML page if the BOM header, PC Browser (IE, Firefox) and Mobile browser (UC) are normal, and if the BOM header, the phone is norm

Example 1 The code is as follows:Copy code /*** Remove the bom header from the file.* @ Var 0.1* @ Author Chenwp*/Function clearbom ($ contents ){// Remove the bom header from the text by UTF8$ BOM = chr (239). chr (187). chr (191 );Return str_replace ($ BOM, '', $ contents );}/*** Remove the

1. JavaScript componentsWhile JavaScript and ECMAScript are often used to express the same meaning, JavaScript has a much larger meaning than what is stated in the ECMA-262 standard. A complete JavaScript should consist of the following three different parts Core (ECMAScript); ECMAScript is a script programming language that is standardized by the ECMA International (formerly the European Asso

BOM 1. BOM is short for Browser Object Model, that is, Browser Object Model. 2. BOM has no relevant standards. 3. The most fundamental object of BOM is window. From 1, we can see that BOM is closely related to the browser. Many browser things can be controlled through JavaSc

Tip: Do not use NotePad to edit the code file and template file, use a tool that can remove the Unicode signature (BOM) edit. If your website is blank, the style is lost, and the program reports an error, you may have used the tool that failed to remove BOM to modify the template file or source code file.Now, almost all text editing software can display and edit UTF-8-encoded files. However, unfortunately,

UTF-8 encoded files are divided into BOM and without BOM two kinds, with the BOM everyone is easy to handle, without BOM will be a little trouble, so write a function to judge, the code is as follows: Returns 1 for pure ASCII (that is, all characters are not greater than 127)Returns 2 indicating UTF8Return 0 indicates

BOM information is a hidden string starting with a file that is used by some editors to identify it as a UTF-8-encoded file. However, PHP reads these characters when reading a file, which leads to some unrecognized characters at the beginning of the file. For example, using the UTF-8 format to save the generated image PHP file, because the file header hidden BOM information is also issued, resulting in the

Interpreting BOM and COM, interpreting BOMCOM Concept: 1. BOM (Browser Object Model ): The browser object model is closely related to the browser by name.

This paper illustrates the method of automatic detection and removal of UTF-8 file BOM in PHP. Share to everyone for your reference. The implementation methods are as follows: BOM information is a string of hidden characters at the beginning of a file that allows some editors to recognize that this is a UTF-8 encoded file. But PHP reads these characters out of the file, creating a problem with the unrecogn

Use PHP to determine if the file is UTF-8 encoded (check Bom ). UTF-8 encoding files are divided into two types with Bom and without Bom, with Bom are easy to handle, without Bom will be a bit of trouble, so write a function to judge, the code is as follows: the returned UTF

With ADODB. Stream, you can easily read and write binary and text streams, read and write files, and specify character set encoding for text streams.However, when ADODB. Stream outputs a text stream of UTF-8 encoding, it will add bom at the front end of the stream.What is Bom: byte order mark, A UTF-8 code-specific tag that occupies 3 bytes of "ef bb bf" at the beginning of the file stream ".What is the use

Http://baike.baidu.com/view/1204863.htm of character encoding related information UTF-8 files can be divided into two formats: No BOM and BOM. A storage or byte stream with a BOM header must be encoded in the Unicode Character Set. In the end belong to that one (UTF-8 or UTF-16 or utf-32), can be determined by the header. In a UTF-8 encoded file,

Bom:byte Order MarkUTF-8 BOM is also called UTF-8 signature, in fact, UTF-8 BOM to UFT-8 has no effect,In order to support UTF-16,UTF-32, the Bom,bom signature means to tell the editor what encoding to use for the current file,The editor is easy to recognize, but the BOM doe

First, explain what Bom is. The full name of BOM is byte order mark. It is not hard to see from its name that it exists to mark byte order. the definition of byte order can be found here because the group in which the http://en.wikipedia.org/wiki/Endianness exists is used to determine the actual storage order of binary data in memory. When the two machines exchange data, the byte order (or endian) must be

What is the BOM header?The BOM header is placed in the header of the UTF-8-encoded file, which occupies three bytes to identify the file as being UTF-8-encoded. Currently, many software programs recognize BOM headers, but some cannot recognize BOM headers. For example, PHP cannot recognize

Preface: When we deal with JSON strings, we often encounter this problem org.json.JSONException:Value of type java.lang.String cannot be converted to Jsonobject, The Jsonobject object throws this exception when parsing the JSON string returned by the server. In fact, this is the return JSON string containing the BOM header caused.Ben is not good at writing. Hope you prawns forgive me!!!what is JSON? JSON (JavaScript Object Notation) is a lightweight d
