Foreach loop problems (only the last variable)
Hey guys, I have a bit of a problem. I get values from textarea as an array, then I do a foreach loop and there it gets messy, I have 2 functions that work with the vars, but only one them works normally, the other one only works on the last objest of an array. (I'm not much of a php specialist so the code might look messy)
<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);
}
?>
Here's the Gtranslate.php (got it from google code):

Gtranslate.php doesn't have any problems it works ok.
So again about my problem, I do a foreach loop from words that are in the textfile, each gets translated into english and then I get another data (but more precise for me) the first part works fine, the second part only works on the last word of the array.
I hope you understand what my problem is.
Thank you in advance for your answers.
try moving your trim to after you're looping through the data, else each line could still have whitespace front and back.

<textarea name="tran" id="tran" rows="25" cols="20"></textarea>
<input name="submit" type="submit" value="Submit">
