I read a csv file with php and print it to the screen with echo.
After printing, there is a utf-8 character problem in the output.
how can i solve this problem?
enter image description here
<?php
$row = 1;
if (($handle = fopen("Liste.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
echo "<p> $row satırındaki $num alan: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
// convert encoding
$data = mb_convert_encoding($data, "UTF-8", "auto");
// str_getcsv
$array = str_getcsv($data);
?>

I have problems with encoding csv file and showing it.
I found function like:
$row = 1;
if (($handle = fopen("1611005286991218.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
//echo "<p> $num fields in line $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
And it's opening but not encoded. This is the first lines of output:
PK!��Y^�[Content_Types].xml
�(����N�0E�H���-Jܲ#5��*Q>�ēƪ_��{&.-�V���J

I tried encoding it with UTF-8, but no success, like so:
echo mb_convert_encoding($data[$c], 'UTF-8', 'windows-1251');
Anyone had similar problems?
When I open the csv file
$str = file_get_contents($filename);
$str = mb_convert_encoding($str,"utf-8","sjis");
var_dump($str);
It shows like this
\0000\000.\0000\0000\0008\0000\0005\0007\000,\0000\000.\0000\0001\0000 ....
At first I think , this is the problem of encoding, so I added mb_convert_encoding but in vain.
What cause this improper encoding?
Better you can do like this:
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
echo "<p> $num fields in line $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
Code copied from :http://php.net/manual/en/function.fgetcsv.php
alternatively : http://php.net/manual/en/function.str-getcsv.php
I want to retrieve for each line all data for a specific column of a csv file.
File structure
Swimlane,Column,ID,Title
For example retrieve all data for the column "Title".
Code:
$row = 1;
if (($handle = fopen("Business Backlog API Publication.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
// Column title
$num = $data[4];
echo "<p> $num : $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
Thank you so much
If file is not huge, you can use file() function:
$lines = file("Business Backlog API Publication.csv");
$row = 0;
foreach($lines as $line)
{
$line = explode(",", $line);
$title = $line[3];
echo "<p> $row : $title: <br /></p>\n";
$row++;
}
Note that title is at index 3, not 4
I need to replace a lot of data in csv and after changing all things i want it saved to a new csv file.
i can read the csv with the code from php.net but i can't get it to work saving the new file. i have this
$row = 0;
if (($handle = fopen("original.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 20000, ";")) !== FALSE) {
$num = count($data);
$cat_alt = ['cold', 'hot', ... and so on...];
$cat_neu = ['kalt', 'heiß', ...und so weiter...];
echo "<p> $num Felder in Zeile $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
$output = str_replace($cat_alt, $cat_neu, $data[$c] . "<br />\n");
echo $output;
}
}
}
$fp = fopen('changed.csv', 'w');
foreach ($row as $rows) {
fputcsv($fp, $rows);
}fclose($fp);
You have two options:
Use n array
$rows = []
...
$rows[] = str_replace($cat_alt, $cat_neu, $data[$c] . "\n");
...
fputcsv($fp, $rows);
Open the output file beforehand and write to it as you process the data
$fp = fopen('changed.csv', 'w');
if (($handle = fopen("original.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 20000, ";")) !== FALSE) {
$num = count($data);
$cat_alt = ['cold', 'hot', ... and so on...];
$cat_neu = ['kalt', 'heiß', ...und so weiter...];
echo "<p> $num Felder in Zeile $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
fputs($fp, str_replace($cat_alt, $cat_neu, $data[$c] . "<br />\n"));
}
}
}
fclose($fp);
I want to take a text file formatted like so:
*note I can change the format of the stored messages, basically there are delimiters and different lines
;68.229.164.10:4/5/2013:Hello
;71.73.174.13:4/6/2013:Oh Hey
(;IPADDRESS:TIMESTAMP:MESSAGE)
and put it in a table that looks like so:
IP Time Message
68.229.164.10 4/6/2013 Hello
71.73.174.13 4/6/2013 Oh Hey
I prefer to use something like the following:
http://php.net/manual/en/function.fgetcsv.php
And then format the output accordingly.
From Example 1 on the above referenced page:
<?php
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
echo "<p> $num fields in line $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
?>
so, you could do something like this...
<?php
$row = 1;
if (($handle = fopen("path_to_your_data_file", "r")) !== FALSE) {
echo '<table>';
echo '<tr><td></td>IP<td>Time</td><td>Message</td></tr>';
while (($data = fgetcsv($handle, 1000, ":")) !== FALSE) {
$num = count($data);
$row++;
if ($num > 2) {
echo '<tr>';
for ($c=0; $c < $num; $c++) {
echo '<td>'.$data[$c].'</td>';
}
echo '</tr>';
}
}
echo '</table>';
fclose($handle);
}
?>
$a=";68.229.164.10:4/5/2013:Hello
;71.73.174.13:4/6/2013:Oh Hey";
preg_match_all('{;(.*?):(.*?):(.*)}',$a,$d);
//set th
$d[0][0]='IP';
$d[0][1]='TIME';
$d[0][2]='Message';
$table = '<table>'.PHP_EOL;
foreach($d AS $tr){
$row = PHP_EOL;
foreach($tr AS $td){
$row .= "<td>{$td}</td>".PHP_EOL;
}
$table .= "<tr>{$row}</tr>".PHP_EOL;
}
$table .= "</table>".PHP_EOL;
echo $table;
