Foreach循環問題（只有最後一個變量）

Question

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）

<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); 
} 
?> 

這裏的Gtranslate.php（從谷歌代碼得到它）：

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。

Answer 1

嘗試在循環播放數據之後移動您的剪輯，否則每行仍可能有空白前後。
