View Full Version : special characters lost from dumpfile through mysql_query

11-07-2007, 04:04 PM
I have a script on my local machine which makes a dumpfile of the local database, then uploads it to the web-server by ftp. After that, a script on the web-server opens (fopen) and reads (fread) the file, splits it into individual queries and passes them through mysql_query() - thus synchronizing the web-server with the local. During that process, special characters - e.g. the Scandinavian æ, ø and å - get lost and become weird signs.

The remote dump-file is located here: http://skred-svalbard.no/dump.sql. If you open that file in a web-browser, the special characters will indeed look weird, example:

INSERT IGNORE INTO `content` VALUES (121,5,'2007-02-01','Safety training in Ny Ã…lesund', (...)
(supposed to be "Ny Ålesund"). However, if you save the file to your drive and open it with a text-editor, you will see that the characters are still intact - it's just the browser which doesn't render them.

Apparently, the characters are not passed correctly from php to the mysql server.

Any suggestions?

Here is the code which reads and passes the dump file to the mysql server:

$file = "dump.sql";
$fh = fopen($file, 'r');
$text = fread($fh, filesize($file));

// insert seperator before each command
$sep=" |SEP| ";
$text=ereg_replace("DROP"," $sep DROP",$text);
$text=ereg_replace("INSERT"," $sep INSERT",$text);
$text=ereg_replace("CREATE"," $sep CREATE",$text);
$text=ereg_replace("--"," $sep --",$text);
$text = eregi_replace(
'', $text); // remove what is btw /* and */

// create array from seperator and run
// queries one-by-one
$sqls=explode(' |SEP| ',$text);
echo "<div class='section'><h2 style='text-align:center;'>SQL commands executed</h2>";
foreach ($sqls as $sql) {
echo "<div style='border:solid 1px #888888;margin:0 auto 8px auto;width:80%;'>
<p style='text-align:left;'>".$sql."</p>";
if ($sql!=" ") {
if (!mysql_query($sql)) {
echo '<p style=\'color:red;\'>ERROR: '.mysql_error().'</p>';
} else {echo "<p style='color:red;'>SUCCES!</p>";
echo "</div>";
echo "</div>";

Please, someone out there must have an idea?

I have read the documentation of fread() and fopen() without finding out.

I tried to add a "b" to the fopen argument:
$fh = fopen($file, 'rb');
- it doesn't help.

I suppose it has something to do with how php reads the data - any alternative functions perhaps?

- through this thread:

Simply adding this:
$text="SET NAMES 'utf8';".$text;
- just before the:
$sqls=explode(" $sep ",$text);
- does the trick!
