Hey everyone, I have a small problem, I have the following script that replaces characters like ü, ö (German characters) with ue, oe, etc. Here is the script: 1<?php
2
3error_reporting(E_ALL);
4
5$dbhost = 'localhost';
6$dbuser = 'root';
7$dbpass = '';
8
9mysql_connect($dbhost, $dbuser, $dbpass) or die(mysql_error());
10mysql_select_db('stavki');
11
12/*mysql_set_charset('utf-8');*/
13mysql_query("SET CHARSET utf-8");
14
15if(isset($_POST['dodaj']))
16{
17 $input2 = $_POST['input'];
18
19 $vn = array('ö', 'ü', 'ä', 'ß', 'Ö', 'Ü', 'Ä', 'Š', 'È', 'Ž', 'š', 'è', 'ž');
20 $not = array('oe', 'ue', 'ae', 'ss', 'OE', 'UE', 'AE', 'S', 'C', 'Z', 's', 'c', 'z');
21
22 $input = str_replace($vn, $not, $input2);
23
24 $besede = explode(" ", $input);
25
26 $stavki = mysql_query("SELECT * FROM stavki") or die(mysql_error());
27
28 echo "IZPIŠEMO VSE MOŽNE BESEDE, KI JIH JE VPISAL UPORABNIK";
29 echo "<pre>";
30 print_r($besede);
31 echo "</pre>";
32 echo "<hr />";
33
34 while($kos = mysql_fetch_array($stavki))
35 {
36
37 $vprasanje = $kos['vpr'];
38 $odgovor = $kos['odg'];
39
40 $vpr2 = str_replace($vn, $not, $vprasanje);
41
42 echo "Debug:<BR />Odgovor: ".$odgovor."<br />";
43 echo "Vprašanje: ".$vpr2."<br />";
44 $a = 0;
45 foreach($besede as $beseda)
46 {
47 if(stristr($vpr2, $beseda))
48 {
49 $a = $a + 1;
50 echo "<font color=\"green\"><b>".$beseda."</b></font> ";
51 }
52 else
53 {
54 echo "<font color=\"red\">".$beseda."</font> ";
55 }
56 }
57 echo "<hr />";
58
59 $konec[] = array("st_ujemanj" => $a, "vpr" => $vprasanje, "odg" => $odgovor);
60 }
61 array_multisort($konec, SORT_DESC);
62 echo "<pre>";
63 print_r($konec);
64 echo "</pre>";
65 echo "<hr />";
66 echo "<b>".$_POST['input']."</b> ";
67 echo $konec[0]['odg'];
68
69}
70?>
71
72<form action="" method="post">
73 Vprašanje: <input type="text" name="input" /><br />
74 <input type="submit" name="dodaj" />
75</form>
Note: not my code I guess what it comes down to is this: 1<?php
2
3if(isset($_POST['dodaj']))
4{
5 $input2 = $_POST['input'];
6
7 $vn = array('ö', 'ü', 'ä', 'ß', 'Ö', 'Ü', 'Ä', 'Š', 'È', 'Ž', 'š', 'è', 'ž');
8 $not = array('oe', 'ue', 'ae', 'ss', 'OE', 'UE', 'AE', 'S', 'C', 'Z', 's', 'c', 'z');
9
10 $input = str_replace($vn, $not, $input2);
11
12 echo $input;
13
14
15}
16?>
17
18<form action="" method="post">
19 Vprašanje: <input type="text" name="input" /><br />
20 <input type="submit" name="dodaj" />
21</form>
I input ü and it outputs ü. Does anyone know how to solve this? Maybe using the MultiByte extension? But AFAIK, it doesnt have a mb_str_replace(). I would really appreciate any help or suggestions. Thank you. In capitalist America bank robs you. |

Adding header("Content-type: text/html; charset=utf-8"); to the top of the file causes the script to work on my server. I don't know why though [append] The behavior is that the browser sends the form data in the same character set as the page that contained the form, and this is supported by this page, but I haven't found anything on W3C. -- Ryan Patterson - <http://cgamesplay.com/> |

First, make sure you are explicitly setting the character encoding type. If you set it to UTF-8, then you only have to handle one case. Second, make sure your file is saved in UTF-8. Then it will work. Reason: The character: "ö" might be stored as 0xF6 (ASCII) or 0xC3B6 (UTF-8) or 0x00F6 (UTF-16) or 0x000000F6 (UTF-32) in your file. In addition to those types, the browser may submit it as ö or ö or ö. (Although for characters < 256, the default is probably always ASCII.) A naive search and replace will only work if both encoding types are the same. |

Maybe if you stopped killing kittens your code would work |

My advice: use UTF-8 for everything. This includes: --- |
