嘿，夥計們，我有點問題。我將textarea的值作爲一個數組，然後我做了一個foreach循環，並且它變得混亂，我有兩個函數可以與變量一起工作，但是隻有一個函數可以正常工作，另一個函數只能工作在數組的最後一個對象上。 （我沒有太大的PHP專家，使代碼看起來凌亂）Foreach循環問題（只有最後一個變量）
<form action="example.php" method="post">
<textarea name="tran" id="tran" rows="25" cols="20"></textarea>
<input name="submit" type="submit" value="Submit">
</form>
<?php
function translate($line) {
$url = "http://m.translate.ru/translator/result/?text=$line&dirCode=gr";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_USERAGENT, "Opera/9.63 (Windows NT 5.1; U; ru) Presto/2.1.1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$html = curl_exec($ch);
curl_close($ch);
preg_match('/<div class=\"tres\">(.*)<\/div><div class=\"tinfo\">/', $html, $translate);
$blabla = strip_tags($translate[0]);
return $blabla;
}
if(isset($_POST['submit'])) {
require("GTranslate.php");
$text = trim($_POST['tran']);
$textAr = explode("\n", $text);
$fp = fopen('data.txt', 'a+');
foreach ($textAr as $line) {
try{
$gt = new Gtranslate;
$transl = $gt->german_to_english($line);
$more_precise = translate($line);
fwrite($fp, $line);
fwrite($fp, "|");
fwrite($fp, $transl);
fwrite($fp, "|");
fwrite($fp, $more_precise);
fwrite($fp, "\n");
} catch (GTranslateException $ge)
{
echo $ge->getMessage();
}
}
fclose($fp);
}
?>

Gtranslate.php沒有按」沒有任何問題，它工作正常。
所以再次關於我的問題，我做了一個foreach循環從文本文件中的單詞，每個被翻譯成英文，然後我得到另一個數據（但更精確的我）第一部分工作正常，第二部分只適用於數組的最後一個單詞。
我希望你明白我的問題是什麼。
非常感謝您的回答。
你怎麼知道它只適用於最後的單詞？你有沒有檢查哪些參數傳遞給'translate（）'？ – 2010-11-09 22:47:38
似乎無法看到任何錯誤。你的翻譯功能似乎沒問題。舉一個輸入數組的例子並輸出結果 – Stewie 2010-11-09 22:50:29
