$var = $_POST['var'];
$new_words = $_POST['new_words'];
$en_word = $_POST['en_word'];
for($i=0; $i<count($var); $i++)
{
$file = '/www/translation.php';
$handle = fopen($file, "r");
$input = fread($handle, filesize($file));
$stringData = html_entity_decode($new_words[$i], ENT_COMPAT, 'UTF-8');
$first_str = "\"$en_word[$i]\""."=>";
$string="\"$stringData\"".",\n";
fclose($handle);
if(!eregi($first_str,$input) && !eregi($string,$input))
{
$myFile = "/www/translation.php";
//echo $en_word[$i];
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = "\"$en_word[$i]\""."=>";
fwrite($fh, $stringData);
$stringData = html_entity_decode($new_words[$i], ENT_COMPAT, 'UTF-8');
fwrite($fh, "\"$stringData\"".",\n");
fclose($fh);
}
elseif (eregi($first_str,$input) && !eregi($string,$input))
{
// here I want to replace the input word if not exist in translation.php.

Answer 1

Please change your html to this:
`<form method='post'>
<input type='hidden' name='var'/>
<input type='hidden' name='en_word[]' value='HOME'/>
<input type='text' name='new_word'/>
<input type='hidden' name='en_word[]' value='REWARD'/>
<input type='text' name='new_word'/>
<input type='hidden' name='en_word[]' value='LEADERBOARDS'/>
<input type='text' name='new_word'/>
<input type='submit'>
`
If not, the post will only havethe last en_word value. Please check if it works now and comeback.
Thanks

So you have a php-file that includes translations for certain keywords like "HOME" and "REWARDS". you then have a form to change the translation for those keywords. on submit you want to replace the old translations with new ones.
Maybe this code can help you solve your problem. i first load the whole translation.php into $contents, then perform a preg_replace search&replace on it.
<?php
// prepare $find and $replace for preg_replace.
$find = array("HOME", "REWARD");
$replace = array("whatever", "foobar");
// convert $find into regular expressions for the whole line
foreach ($find as $i => $key)
$find[$i] = '~("'.$key.'"\s*=>\s*")[^"]*(",\r?\n?)~u';
// convert $replace to use the first and second part of any match
// and put the new translation in between
foreach ($replace as $i => $translation)
$replace[$i] = '$1'.$translation.'$2';
// read translation.php
$contents = file_get_contents("translation.php");
// do the replacements
$contents = preg_replace($find, $replace, $contents);
// debug output, just delete later
var_dump($find, $replace, $contents);
// you want to save your changes into translation.php
// file_put_contents("translation.php", $contents);
?>
if you have to manage more than a few values in your translation.php, consider using a database like mysql to do this. changing the values and even having multiple language support is way easier with mysql.
there also is a special library for handling translations of text: http://php.net/manual/de/book.gettext.php
