UTF8到php中的等效数字 [英] UTF8 to equivalent number in php

问题描述

我一直在搜索我的！试图找到一个PHP函数将UTF8转换为等效数字。我不完全知道该叫什么号码（我听说它被称为一个纵坐标），但是还有一个例子： http://jrgraphix.net/r/Unicode/3040-309F

基本上我正在读取一个UTF-8 .txt文件在PHP中，然后保存数组中的每一行，所以我可以搞砸它。

如果有人可以帮助我，这将是非常感谢，因为我是不熟悉UTF8。

编辑：
这是我到目前为止这样：

  echovar TextCharacters = new Array（）; \\\
; 
 
 $ LineArray = array（）; 
 $ file_handle = fopen（lesson1.txt，r）; 
 
 
 while（！feof（$ file_handle））
 {
 $ line_of_text = fgets（$ file_handle）; 
 array_push（$ LineArray，$ line_of_text）; 
} 
 
 fclose（$ file_handle）; 
 
 foreach（$ LineArray as $ s）
 {
 for（$ i = 0; $ i< mb_strlen（$ s，utf-8）; $ i ++ ）
 {
 $ char = mb_substr（$ s，$ i，1，utf-8）; 
 echoalert（go（。bin2hex（iconv（'UTF-8'，'UCS-2'，$ char）））））;; 
} 
} 
  

解决方案

您正在寻找的是Unicode代码点，即Unicode字符表中已知字符的数字标识符。 最便宜的方法是通过UCS-2字符编码，将1：1从字节映射到Unicode代码点：

  echo bin2hex（iconv（'UTF-8'，'UCS-2'，'あ'））; 
 // 3042 
  

注意事项：返回的代码始终为4个十六进制数字可能或可能不喜欢），UCS-2不支持高于BMP的字符，即高于代码点FFFF。

I've been searching my !!! off trying to find a PHP function to convert UTF8 to the equivalent number. I'm not entirely sure what to call the number (I heard its called an ordinate?) but heres an example: http://jrgraphix.net/r/Unicode/3040-309F

Basically I'm trying to read a UTF-8 .txt file in PHP and then save every line in an array, so I can mess around with it.

If anyone can assist me with this it would be highly appreciated, as I am not that familiar with UTF8 yet.

Edit: This is what I've got so far:

echo "var TextCharacters = new Array();\n";

$LineArray = array();
$file_handle = fopen("lesson1.txt", "r");


while (!feof($file_handle)) 
{
  $line_of_text = fgets($file_handle);  
  array_push($LineArray, $line_of_text);
}

fclose($file_handle);

foreach($LineArray as $s)
{
    for($i = 0; $i < mb_strlen($s,"utf-8"); $i++)
    {
        $char = mb_substr($s, $i, 1, "utf-8");
        echo "alert(go(" . bin2hex(iconv('UTF-8', 'UCS-2', $char)) . "));";         
    }
}

解决方案

What you're looking for is the Unicode code point, i.e. the numeric identifier by which the character is known in the Unicode character table. The "cheapest" way to do this is through the UCS-2 character encoding, which maps 1:1 from bytes unto the Unicode code points:

echo bin2hex(iconv('UTF-8', 'UCS-2', 'あ'));
// 3042

Caveats: the returned code is always 4 hexadecimal digits long (which you may or may not like) and UCS-2 does not support characters higher than the BMP, i.e. higher than code point FFFF.
