hi!
i hope this is the right group for my question, if i got it wrong, please accept my apologies and tell me where to go next.
i have a form which needs to accept strings with specific central european, japanese, russian, etc. charactres. the site accepts utf-8, all headers are sent for utf-8 and on windows, where i'm testing it, all works ok. eg. i enter something in japanese, korean, russian, slovene, etc. and if i put everything through this:
ereg_replace ("[^[:alnum:]\n]", "", $t)all japanese, russian, etc. characters remain in the string, as i'd like them to.
but when i test this same function on dragonflybsd or freebsd, all those characters get stripped out.
php.ini settings, mbstring section has the overload setting set to overload everything, so php should basically be using mb_ereg_replace. just to be sure, i tried that function specifically.
my test environments are:
win2k, sp4, apache 2.0.50, php 4.3.8 (here, it works ok)
freebsd 5.2.1, fully patched, apache-1.3.31_4, mod_php4-4.3.8_2,1 (doesn't work)
dragonflybsd, latest version, today freshly installed apache and php from ports, also doesn't work
could someone please help me, point me in the right direction, tell me what i am doing wrong or just explain why such a difference on windows and the bsd platforms? i couldn't test it on a linux platform since i don't have access to one. am i expectinh too much from ereg* functions if i want them to tell me if some foreign characters are valid in some alphabet or should i take a different approach?
thank you for any information!
i have mbstring extension installed and here are my php.ini mbstring settings:
[mbstring]
mbstring.language = Neutral
mbstring.internal_encoding = UTF-8
mbstring.http_input = UTF-8
mbstring.http_output = UTF-8
mbstring.encoding_translation = On
mbstring.substitute_character = _
mbstring.func_overload = 7
this is the (very simple) script i am using for testing: ___________________________ <?php
header("content-type:text/html; charset=utf-8");unset ($t);
if (isset ($_POST['t']))
{
$t = $_POST['t'];
}?> <?xml version="1.0" encoding="utf-8"?> <head> <title>mad scientists not a work</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> </head>
<body> <div align="center"> <?php
if (isset ($t))
{
echo "<pre>Got this:\n" . $t . "\n</pre>";
echo "<hr><br><pre>put through preg_replace:\n" . preg_replace ("/[^[:alnum:]\n]/", "", $t) . "\n</pre>";
echo "<hr><br><pre>put through ereg_replace:\n" . ereg_replace ("[^[:alnum:]\n]", "", $t) . "\n</pre>";
}
?>
<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post">
<textarea name="t" rows="7" cols="60"><?php if (isset ($t)) echo $t; ?></textarea>
<br />
<input type="submit">
</form>
</div>
</body>
