Question

我想插入一些数据，这些数据来自谷歌翻译。例如： http://translate.google.com/translate_a/t?client=t&hl=en&sl=auto&tl=fa&multires=1&prev=btn&ssel=0&tsel=3&uptl=fa&alttl=en&sc=1&text=hello

收到结果后，我想将其插入MySQL表中。所以我写了下面的代码：

$link     = "http://translate.google.com/translate_a/t?client=t&hl=en&sl=auto&tl=fa&multires=1&prev=btn&ssel=0&tsel=3&uptl=fa&alttl=en&sc=1&text=";

$server   = "127.0.0.1";
$username = "AliAhmadi";
$password = "AliAhmadi";
$database = "AliAhmadi";

$conn     = mysql_pconnect($server, $username, $password);
if (!$conn)
     die("Bye Bye");
mysql_select_db($database, $conn);
mysql_set_charset('utf8',$conn);
$ch       = curl_init();
$url          = $link."hello";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$WebContent   = curl_exec($ch);
$update_query = 'update `en_db` SET `meaning`="'.mysql_real_escape_string($WebContent).'" where `id`=1';
mysql_query($update_query,$conn);
mysql_close($conn);

Google发送了以下文本文件：

[[["سلام", "hello", "", ""]], [["interjection", ["سلام", "هالو", "الو"], [["سلام", ["hello", "hi", "aloha", "all hail"]], ["هالو", ["hallo", "hello", "halloo"]], ["الو", ["hello"]]]]], "en", , [["سلام", [5], 0, 0, 1000, 0, 1, 0]], [["hello", 4, , , ""], ["hello", 5, [["سلام", 1000, 0, 0], ["خوش", 0, 0, 0], ["میهمان گرامی", 0, 0, 0], ["خوش آمدید", 0, 0, 0], ["درود کاربر", 0, 0, 0]], [[0, 5]], "hello"]], , , [["en"]], 74]

但是在表格中只保存了字符串的第一部分：

[[["

我认为问题来自unicode，因为当我评论mysql_set_charset('utf8',$conn);时，它会在表格中保存一些东西，但看起来像

[[["Èå","to","",""]],[["preposition",["Èå","ÈÑÇ\u06CC","ÏÑ","ÏÑ ÈÑÇÈÑ","\u06CCÔ","Óæ\u06CC","äÒÏ","ØÑÝ","ÈÓæ\u06CC","ÊÇ äÓÈÊ Èå","ÈÑ ÍÓÈ","ÈØÑÝ","ÑæÈØÑÝ"],[["Èå",["to","into","in","on","at","against"]],["ÈÑÇ\u06CC",["for","to","on","for the sake","toward","in order that"]],["ÏÑ",["at","to","about","unto"]],["ÏÑ ÈÑÇÈÑ",["against","versus","to","for","unto"]],["\u06CCÔ",["before","to","with","unto"]],["Óæ\u06CC",["to","unto"]],["äÒÏ",["to","near","about"]],["ØÑÝ",["towards","to"]],["ÈÓæ\u06CC",["toward","to","into","off","unto","at"]],["ÊÇ äÓÈÊ Èå",["to","unto"]],["ÈÑ ÍÓÈ",["according to","in","at","to"]],["ÈØÑÝ",["toward","at","unto","to","in","into"]],["ÑæÈØÑÝ",["unto","to"]]]],["",["ÚáÇãÊ ãÕÏÑ Çäá\u06CCÓ\u06CC ÇÓÊ"],[["ÚáÇãÊ ãÕÏÑ Çäá\u06CCÓ\u06CC ÇÓÊ",["to"]]]]],"en",,[["Èå",[5],0,0,1000,0,1,0]],[["to",4,,,""],["to",5,[["Èå",1000,0,0],["ÈÑÇ\u06CC",0,0,0],["ÊÇ",0,0,0],["ÑÇ Èå",0,0,0],["Èå ãäÙæÑ",0,0,0]],[[0,2]],"to"]],,,,5]

google翻译器返回的unicode是什么？这个代码我的问题在哪里？我在utf8_unicode_ci，utf8_general_ci和utf8_presian_ci之间更改了Collation，但这个问题又发生了。

Answer 1

我认为您的en_db.meaning列定义为默认排序规则latin1_swedish_ci。这使用ISO-8859-1（Latin-1）编码，该编码无法存储阿拉伯字符。

（当您删除mysql_set_charset调用时，MySQL会将您的UTF-8阿拉伯语误解为拉丁字符，这些字符适合该列，但看起来完全错误。）

确保在创建表时指定使用UTF-8的排序规则，例如CREATE TABLE en_db (...) COLLATE utf8_general_ci或一般(...) CHARACTER SET utf8（或utf8mb4用于星体平面支持（如果可用））。

您可以使用ALTER TABLE en_db CONVERT TO CHARACTER SET utf8更改现有表及其中所有文本列的排序规则，但如果您已经有非ASCII字符，则无论哪种方式都可能出错。

Answer 2

<?php
//Set Beginning of php code:
header("Content-Type: text/html; charset=UTF-8");
mysql_query("SET NAMES 'utf8'"); 
mysql_query('SET CHARACTER SET utf8');

//then create the connection 
$CNN=mysql_connect("localhost","usr_urdu","123") or die('Unable to Connect');
$DB=mysql_select_db('db_urdu',$CNN)or die('Unable to select DB');

使用UTF-8时无法将字符串插入MySQL
