I try to read a CSV and echo the content. But the content displays the characters wrong.
Mäx Müstermänn -> Mäx Müstermänn
Encoding of the CSV file is UTF-8 without BOM (checked with Notepad++).
This is the content of the CSV file:
"Mäx";"Müstermänn"
My PHP script
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<?php
$handle = fopen ("specialchars.csv","r");
echo '<table border="1"><tr><td>First name</td><td>Last name</td></tr><tr>';
while ($data = fgetcsv ($handle, 1000, ";")) {
$num = count ($data);
for ($c=0; $c < $num; $c++) {
// output data
echo "<td>$data[$c]</td>";
}
echo "</tr><tr>";
}
?>
</body>
</html>
I tried to use setlocale(LC_ALL, 'de_DE.utf8'); as suggested here without success. The content is still wrong displayed.
What I'm missing?
Edit:
An echo mb_detect_encoding($data[$c],'UTF-8'); gives me UTF-8 UTF-8.
echo file_get_contents("specialchars.csv"); gives me "Mäx";"Müstermänn".
And
print_r(str_getcsv(reset(explode("\n", file_get_contents("specialchars.csv"))), ';'))
gives me
Array ( [0] => Mäx [1] => Müstermänn )
What does it mean?
Try this:
<?php
$handle = fopen ("specialchars.csv","r");
echo '<table border="1"><tr><td>First name</td><td>Last name</td></tr><tr>';
while ($data = fgetcsv ($handle, 1000, ";")) {
$data = array_map("utf8_encode", $data); //added
$num = count ($data);
for ($c=0; $c < $num; $c++) {
// output data
echo "<td>$data[$c]</td>";
}
echo "</tr><tr>";
}
?>
Encountered similar problem: parsing CSV file with special characters like é, è, ö etc ...
The following worked fine for me:
To represent the characters correctly on the html page, the header was needed :
header('Content-Type: text/html; charset=UTF-8');
In order to parse every character correctly, I used:
utf8_encode(fgets($file));
Dont forget to use in all following string operations the 'Multibyte String Functions', like:
mb_strtolower($value, 'UTF-8');
The problem is that the function returns UTF-8 (it can check using mb_detect_encoding), but do not convert, and these characters takes as UTF-8. ?herefore, it's necessary to do the reverse-convert to initial encoding (Windows-1251 or CP1251) using iconv. But since by the fgetcsv returns an array, I suggest to write a custom function: [Sorry for my english]
function customfgetcsv(&$handle, $length, $separator = ';'){
if (($buffer = fgets($handle, $length)) !== false) {
return explode($separator, iconv("CP1251", "UTF-8", $buffer));
}
return false;
}
In my case the source file has windows-1250 encoding and iconv prints tons of notices about illegal characters in input string...
So this solution helped me a lot:
/**
* getting CSV array with UTF-8 encoding
*
* @param resource &$handle
* @param integer $length
* @param string $separator
*
* @return array|false
*/
private function fgetcsvUTF8(&$handle, $length, $separator = ';')
{
if (($buffer = fgets($handle, $length)) !== false)
{
$buffer = $this->autoUTF($buffer);
return str_getcsv($buffer, $separator);
}
return false;
}
/**
* automatic convertion windows-1250 and iso-8859-2 info utf-8 string
*
* @param string $s
*
* @return string
*/
private function autoUTF($s)
{
// detect UTF-8
if (preg_match('#[\x80-\x{1FF}\x{2000}-\x{3FFF}]#u', $s))
return $s;
// detect WINDOWS-1250
if (preg_match('#[\x7F-\x9F\xBC]#', $s))
return iconv('WINDOWS-1250', 'UTF-8', $s);
// assume ISO-8859-2
return iconv('ISO-8859-2', 'UTF-8', $s);
}
Response to @manvel's answer - use str_getcsv instead of explode - because of cases like this:
some;nice;value;"and;here;comes;combinated;value";and;some;others
explode will explode string into parts:
some
nice
value
"and
here
comes
combinated
value"
and
some
others
but str_getcsv will explode string into parts:
some
nice
value
and;here;comes;combinated;value
and
some
others
Try putting this into the top of your file (before any other output):
<?php
header('Content-Type: text/html; charset=UTF-8');
?>
