I had similar problems using the Norwegian letter "Ã" as the first letter in
the elements it was simply not there after the fgetcsv transfer. The following
WORKAROUND worked for me using explode().
dee ell ell at fugro dot no
//read the text file into a variable
$txt=read_txtfile("test.txt");
//explode the stream into an array of $nr rows
$rowArr = explode("\n", $txt);
$nr=count($rowArr);
For ($r=0;$r<$nr;$r++){
$insert_data="'".str_replace(";", "','",$rowArr[$r])."'";
//insert each row in the DB table "test"
$query_string=" INSERT INTO test (name,name2)"
." VALUES (".$insert_data.")";
$result_id = mysql_query($query_string, $my_conn)
or die("display_db_query:" . mysql_error());
}
If ($result_id ==1){echo $nr." rows transfered<br />\n"; }
Function read_txtfile($infile){
// read text data from file into a variable
$txt='';
$fo=fopen($infile,"r");
$txt=fread($fo,filesize($infile));
fclose($fo);
return $txt;
}
===================================================================
If there is a need to access each data column in the row before transferring,
these can easily be accessed by exploding each row once more in an inner loop.

In the window-versions it works correct,
I got the error under php 5.2.6-1+lenny13

Description:
------------
fgetcsv() throws away the first character of a field if it is invalid in the
current locale, but ignores invalid characters which are not at the beginning
of a field. The inconsistent behavior makes it hard to locate the source of the
bug; it should either throw all invalid characters away, or none of them (IMO
the second is much better).
(This is a duplicate of bug 45356, but that one has been closed as "no
feedback", and apparently mere mortals are not allowed to reopen it, even if
they do provide the feedback...)
Test script:
---------------
<?php
setlocale(LC_ALL,'C');
$utfchar = chr(0xC3).chr(0x89); // U+009C in UTF-8
$csv = $utfchar."x".$utfchar."x\n";
file_put_contents('test.csv', $csv);
$file = fopen('test.csv', 'r');
$data = fgetcsv($file);
for ($i = 0; $i < strlen($data[0]); $i++) {
echo dechex(ord($data[0][$i])).' ';
}
echo "\n";
unlink('test.csv');
// expected: c3 89 78 c3 89 78 - "ÃxÃx"
// actual: 78 c3 89 78 - "xÃx"
?>
