How can I split a csv file into arrays? If the row starts with the letter M I would create a new array and push next lines to it until I had again a row with letter M.
At this moment I push all staff to same array.
while (($data = fgetcsv($handle, 1000, ';')) !== FALSE) {
if($data[0] == 'M'){
$costumerDetail[$x] = $data;
}
else {
$costumerDetail[] = $data;
}
$x++;
}
fclose($handle);
The main concept is there, using $x to keep track of the array position, but you then go back and just add the next values to the same part level of the array.
This code adds the missing part which is a multidimensional array, so $x is the main thing that keeps track of which set of data you are in and you just add it into that dimension of the array (using [$x][]) till the next M occurs...
$costumerDetail = [[]];
$x = 0;
while (($data = fgetcsv($handle, 1000, ';')) !== FALSE) {
if($data[0] == 'M'){
$x++;
$costumerDetail[$x] = [];
}
$costumerDetail[$x][] = $data;
}
fclose($handle);

I have a csv file that contains several empty cells like this :
I would like every time the value in the 'Style' column changes that the empty cells take the values of the same style, like this:
I don't really see how I will be able to proceed to put the expected values in the cells, if someone could help me it would be a great help...
<?php
//uploaded xlsx file recovery
$xlsx="C:/wamp64/www/Extract_pictures_Excel/xlsx_files/".date('Y_m_d H-i-s')."_file.xlsx";
move_uploaded_file($_FILES["mon_fichier"]["tmp_name"],$xlsx);
// Excel in CSV
$excel = PHPExcel_IOFactory::load($xlsx);
$writer = PHPExcel_IOFactory::createWriter($excel, 'CSV');
$writer->setDelimiter(";");
$writer->setEnclosure("");
$nomcsv = "C:/wamp64/www/Extract_pictures_Excel/csv/".date('Ymd_His').".csv";
$writer->save($nomcsv);
$delimiter = ";";
$csv_data = array();
$row = 1;
if (($handle = fopen($nomcsv, 'r')) !== FALSE) {
while (($data = fgetcsv($handle, 1000, $delimiter)) !== FALSE) {
//I tried this for if this value changes put back the old ones
$data = $data[5] ?: $data[5];
$csv_data[] = $data;
$row++;
}
fclose($handle);
}
if (($handle = fopen($nomcsv, 'w')) !== FALSE) {
foreach ($csv_data as $data) {
fputcsv($handle, $data, $delimiter);
}
fclose($handle);
}
?>
You need to keep track of the previous style, a simple way would be to set it to blank initially and if the element is blank - set it from the previous style. Note that you only should be updating that element of the array (so add [5] to the assignment)...
$prevData = [];
while (($data = fgetcsv($handle, 1000, $delimiter)) !== FALSE) {
// Overlay current values over the previous values
$data = array_replace ( $prevData, array_filter($data));
// Store current data for future use
$prevData = $data;
$csv_data[] = $data;
$row++;
}
$arr=array();
$row = -1;
if (($handle = fopen("out.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
$row++;
for ($c = 0; $c < $num; $c++) {
$arr[$row][$c]= $data[$c];
}
}
fclose($handle);
}
I'm using this code to read excel file data, this code counts elements in a row that are divided by comma (,),
Name, Surname, Num, Tel
Name
Surname
Num
tel
but in one field I have word Orginal, and this code also divides element by that word like this:
Orgina
l
and in that way, I receive wrong elemnts, any help?
In the line
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
the 1000 is the maximum length of data to read, as your data (in the example posted) has more than that, it will split the data.
To allow it to read the data properly you can just leave the second and third parameters as defaults ( null for length - in other words any length and the default delimiter is a comma anyway...
while (($data = fgetcsv($handle)) !== FALSE) {
I have data as below in a CSV file. The green lines are what I'd like to keep.
Basically if someone has a single line, I want to keep it.
If they have multiple lines, I want to remove any where the 3rd column is A - Fully Fit.
After running through the whole file, I then want to save it over the original.
I tried writing the code but not sure if it's a Friday but the logic is escaping me at the moment.
There could be just a single line or there could be dozens. So if an ID has 1000 rows, I would just want to delete the rows for that ID where the 4th column is "A - Fully Fit"
UPDATE
This code works but not sure if it's the most optimal
// DECLARE ARRAYS
$a = Array();
$b = Array();
$c = Array();
// LOOP THROUGH FILE AND COLLECT DUPLICATES
if (($handle = fopen($filename, "r")) !== FALSE) {
while (($line = fgetcsv($handle, 4096, ",")) !== FALSE) {
$a[$line[1]][] = 'SHAKKA';
}
foreach ($a as $k=>$v) {
if (count($v)>1) {
$b[] = $k;
}
}
}
// IF A DUPLICATE THEN REMOVE ROWS THAT ARE 'A - Fully Fit'
if (($handle = fopen($filename, "r")) !== FALSE) {
while (($golly = fgetcsv($handle, 4096, ",")) !== FALSE) {
if (in_array($golly[1],$b) && $golly[3] == 'A - Fully Fit') {
}
else {
$c[] = $golly;
}
}
}
fclose($handle);
// WRITE THE FILE
$fp = fopen($filename, 'wa+');
foreach ($c as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);
<?php
if (($handle = fopen($filename, "r")) !== FALSE) {
$new_rows = [];
$hash_ids = [];
while (($line = fgetcsv($handle, 4096, ",")) !== FALSE) {
if($line[3] === 'A - Fully Fit'){
if(isset($hash_ids[$line[1]])) continue;
$hash_ids[$line[1]] = true;
}
$new_rows[] = $line;
}
fclose($handle);
// WRITE TO THE FILE
$fp = fopen($filename, 'wa+');
foreach ($new_rows as $current_row) {
fputcsv($fp,$current_row);
}
fclose($fp);
}
In the above code, we maintain a hash(associative array) for each ID. If we have already come across with an ID with A - Fully Fit, then we skip the row, else we add it to the list.
Pretty new to PHP. I have a csv feed that i am trying to display every line of in the right place. The feed is loaded into a multidimentional array and I can echo out specific places like this.
echo $readcsv[0][2]
But I am trying to use the value of the variable $row in stead of the first number while doing a while loop.
Something like:
echo $readcsv[$row][2]
I have tried next(), str_replace() and strtr() but none of them seems to work while the loop is running.
$row = 1;
$readcsv = array();
if (($handle = fopen("file.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {
$num = count($data);
echo $readcsv[$row][2];
$row++;
for ($c=0; $c < $num; $c++) {
}
$mycsvfile[] = $data;
}
fclose($handle);
}
CSV file:
title;image_link;link;empty;price;
1;back.gif;http://link.com;;19.95;
2;back.gif;http://link.com;;19.95;
3;back.gif;http://link.com;;19.95;
4;back.gif;http://link.com;;19.95;
5;back.gif;http://link.com;;19.95;
I am not quite sure from your code and question exactly what you are trying to do, but maybe its something like this
if (($handle = fopen("file.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {
// you load the line into $data and its a one dimentional array
// occurance 2 is the `link` (http://link.com) if that what you want to echo
echo $data[2];
// as you have a loop, maybe you were trying to
// echo each fields from the csv so you can do that like this
foreach ($data as $idx => $value) {
echo "Column $idx = $value";
}
$mycsvfile[] = $data;
}
fclose($handle);
}
I currently have some code like this:
$handle = fopen($_FILES['file']['tmp_name'], "r");
$i = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== false) {
if($i > 0) {
$sql = "
insert into TABLE(A, B, C, D)
values ('$data[0]', '$data[1]', '$data[2]', '$data[3]')
";
$stmt = $dbh -> prepare($sql);
$stmt->execute();
}
$i++;
}
fclose($handle);
This allows me to write to a certain table the contents of a CSV file, excluding the first row where all the names are. I want to be able to extract only the filled rows. How would I use so using this code?
fgetcsv returns an array consisting of a single null if the rows are empty
http://www.php.net/manual/en/function.fgetcsv.php
so you should be able to do a check based on that.
if ($data[0]===null)
{
continue;
}
or something like that
fgetcsv() returns an array with null for blank lines so you can do something like below.
$handle = fopen($_FILES['file']['tmp_name'], "r");
$i = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== false) {
if (array(null) === $data) { // ignore blank lines
continue;
}
if($i > 0) {
$sql = "
insert into TABLE(A, B, C, D)
values ('$data[0]', '$data[1]', '$data[2]', '$data[3]')
";
$stmt = $dbh -> prepare($sql);
$stmt->execute();
}
$i++;
}
fclose($handle);
Based on the documentation, fgetcsv will return an array consisting of a single null value for empty rows, so you should be able to test the return value against that and skip blank lines that way.
The following example code will skip processing blank lines. Note that I have changed the file and removed some other logic to make it more easily testable.
<?php
$handle = fopen("LocalInput.txt", "r");
$i = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== false) {
if($data== array(null)) continue;
var_dump($data);
$i++;
}
fclose($handle);
?>
