PHP Encoding type - php

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

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?

How to adapt PHP CSV utf-8?

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);
?>

Open csv file improper encoding

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);
}

Retrieve columns data for each line csv

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

PHP open csv and save data to new csv

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);

How to transform while loop into foreach loop in the context of using fopen and fgetcsv functions?

This is the standard code on php.net:
<?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);
}
?>
Let's assume that test.csv has 3 rows with:
cell11,cell12,cell13
cell21,cell22,cell23
cell31,cell32,cell33
Is it possible to use a foreach loop instead of the while used here and still get the values inside test.csv, for further use?
The code above gives this result:
3 fields in line 1:
cell11
cell12
cell13
3 fields in line 2:
cell21
cell22
cell23
3 fields in line 3:
cell31
cell32
cell33
This is what I have tried:
<?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";
// }
// }
foreach(($data = fgetcsv($handle, 1000, ",")) as $field){
$num = count($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 the result:
3 fields in line 1:
cell11
cell12
cell13
3 fields in line 2:
cell11
cell12
cell13
3 fields in line 3:
cell11
cell12
cell13

This:
foreach(($data = fgetcsv($handle, 1000, ",")) as $field){ ...
Passes the data from fgetcsv to the new variable $data which doesn't make sense in this case. You can just write this:
foreach (fgetcsv($handle, 1000, ",") as $field) { …
But to explain why foreach doesn't work:
As fget (and thus fgetcsv) is a function it does not work as an array, it just returns one, namely the next line in the file.
The foreach example above just gets the first line from that function and iterates over it. This means you iterate over each column of the first line.
