First, detect the current string encoding and change the encoding to Utf-8 1 Gets the encoding of the current string $encode = mb_detect_encoding ($str, Array ("ASCII", ' UTF-8 ', "GB2312", "GBK", ' BIG5 ')); 2 change character encoding to Utf-8 $str _encode = mb_convert_encoding ($str, ' UTF-8 ', $encode); Sec
The principle is very simple, because gb2312gbk is a Chinese byte, the two bytes have a value range, while UTF-8 contains three Chinese characters, and each byte also has a value range, english, regardless of the encoding, is less than 128, takes only one byte, full angle... the principle is very simple, because gb2312/gbk is a Chinese byte, the two bytes have a value range, while the Chinese character in UTF-8 is three bytes, and each byte also has a
I. Coding rules for BASE64 The idea of BASE64 encoding is to encode the data using 64 basic ASCII characters. It splits the data that needs to be encoded into a byte array. A group of 3 bytes. Arrange the 24-bit data in order, then divide the 24-bit data into 4 groups, that is, 6 bits per group. Then fill a byte with two 0 in front of each group's top digit. This encodes a 3-byte-A-group of data back into 4 bytes. When the number of bytes of data to b
When iconv encounters a character that cannot be transcoded, the interrupted content is lost. the code is as follows: $ c amp; lsquo; test amp; bull; character transfer amp; bull; Happy May Day! Amp; rsquo; echoiconv ( amp; lsquo; UTF-8 amp; prim Iconv is interrupted when transcoding fails. the code is as follows: $ C = 'Test • character transfer • Happy May Day! '; Echo iconv ('utf-8', 'gbk', $ c ); Only output: After the test,
Compile ffmpegin windows. Generally, mingww.msys. compile the windowsexecutable file ffmpeg.exe. When I read the FFMPEG source code, I found that FFMPEG supports pipe. In other words, the input file parameters and output file parameters transmitted to the ffmpeg.exe process do not need to be the hard disk file path. The entire process can be completed directly in the memory. Test method: 1. Use VC to call createnamedpipe to create a named pipe. Note that the opened space must contain at le

91flv video Playback system with the rise of video sharing sites, as well as the popularity of smartphones, a large number of offline video transcoding needs to be done to accommodate heterogeneous networks and multi-terminal environments, 2009 started the development of the video transcoding platform (converting various formats of video files into H264 encoded mp4,3gp files), And in June 2010 launched the
Because the Json_encode () method that converts an array to JSON can only convert the Utf-8 character set, the Chinese characters in the UTF-8 format will be null, and the character in the array needs to be uniformly transcoded, but the Iconv () method can only convert string type encoding , the following methods can be found on the Internet to solve the problem of transcoding of string type and array type
