In {code...} PHP, how can we efficiently retrieve the first 10 of these arrays and determine the number of keys whose key is 333.
array ( 22 => 3000, 1 => 2900, 8 => 2588, 11 => 2400, 6 => 2000, 30 => 1900, 39 => 1800, 25 => 1400, 40 => 1300, 100 => 1244, 15 => 1000, 69 => 900, 70 => 888, 3 => 666, 333 => 10 );
In PHP, how can such an array efficie
that we are writing varchar2 (100 char), so no matter it is a number, letter, Chinese character, it is regarded as a single character, a maximum of 100 write, of course, the more Chinese characters, the larger the space occupied, the above database encoding principles are also followed. For example, if a Chinese character is saved, the bottom layer occupies 2 or 3 bytes, and a letter occupies 1 byte,Definitely not in some articles12 letters or numbersOr 3Bytes!
Nvarchar2 (): No byte, CharSimila
Msc_ver defines the version of the compiler. Here are the _msc_ver values for some compiler versions (see the link to reference 2 in extended reading)Msvc++ 12.0 _msc_ver = = 1800 (Visual Studio) msvc++ 11.0 _msc_ver = 1700 (Visual Studio) msvc++ 10.0 _msc_ver = = (Visual Studio) msvc++ 9.0 _msc_ver = = (Visual Studio) msvc++ 8.0 _msc_ver = 1400 (visual Studi O 2005) msvc++ 7.1 _msc_ver = = 1310 (Visual Studio 2003) msvc++ 7.0 _msc_ver = 1300msvc+
character, all as a character, write up to 100, of course, the more Chinese characters, occupy more space, also follow the database coding principle above. For example: In a Chinese character, the bottom 2 or 3 bytes, deposited in a letter, accounting for 1 bytes, is definitely not some of the article said 1 letters or numbers also accounted for 2 or 3 bytes! nvarchar2 (): No byte,char , similar to VARCHAR2 (char), except Nvarchar2 () block the database encoding, regardless of the encoding, NV
