i have a csv file with values,
i want to add a column ID with an increasing number for each row.
I see this page: [http://www.w3schools.com/php/func_filesystem_fputcsv.asp]
in this case i have an array defined but i want first count the row of the csv, than for each row add a column with a value.
Anybody can suggest me a way?
<?php
$list = array
(
"Peter,Griffin,Oslo,Norway",
"Glenn,Quagmire,Oslo,Norway",
);
$file = fopen("contacts.csv","w");
$i = 0;
foreach ($list as $line)
{
$newline = $line . "," . $i;
fputcsv($file,explode(',',$newline));
$i++;
}
fclose($file); ?>

i am fairly new to PHP and tried several hours to get something going, sadly without a result. I hope you can point me into the right direction.
So what i got is a CSV file containing Articles. They are separated into diff columns and always the same structure, for example :
ArtNo, ArtName, ColorCode, Color, Size
When an article has different color codes in the CSV, the article is simply repeated with the same information except for the color code, see an example:
ABC237;Fingal Edition;48U;Nautical Blue;S - 5XL;
ABC237;Fingal Edition;540;Navy;S - 5XL;
My problem is, i want to display all the articles in a table, include an article image etc.. so far i got that working which is not a problem, but instead of showing the article twice for every different color code i want to create only one line per ArtNo (First CSV Line) but still read the second duplicate line to add the article color to the first one, like :
ABC237; Fingal Edition ;540;Nautical Blue, Navy;S - 5XL;
Is this even possible or am I going into a complete wrong direction here? My code looks like this
<?php
$csv = readCSV('filename.csv');
foreach ($csv as $c) {
$artNo = $c[0]; $artName = $c[1]; $colorCode = $c[2]; $color = $c[3]; $sizes = $c[4]; $catalogue = $c[5]; $GEP = $c[6]; $UVP = $c[7]; $flyerPrice = $c[8]; $artDesc = $c[9]; $size1 = $c[10]; $size2 = $c[11]; $size3 = $c[12]; $size4 = $c[13]; $size5 = $c[14]; $size6 = $c[15]; $size7 = $c[16]; $size8 = $c[17]; $picture = $c[0] . "-" . $c[2] . "-d.jpg";
// Echo HTML Stuff
}
?>
Read CSV Function
<?php
function readCSV($csvFile){
$file_handle = fopen($csvFile, 'r');
while (!feof($file_handle) )
{
$line_of_text[] = fgetcsv($file_handle, 0, ";");
}
fclose($file_handle);
return $line_of_text;
}
?>
I tried to get along with array_unique etc but couldn't find a proper solution.
Read all the data into an array, using the article number as the key....
while (!feof($file_handle) ) {
$values = fgetcsv($file_handle, 0, ";");
$artno = array_shift($values);
if (!isset($data[$artno])) $data[$artno]=array();
$data[$artno][]=$values;
}
And then output it:
foreach ($data as $artno=>$v) {
$first=each($v);
print $artno . "; " . each($first);
foreach ($v as $i) {
$discard=array_shift($i);
print implode(";", $i);
}
print "\n";
}
(code not tested, YMMV)
You need to know exactly how many items belong to each ArtNo group. This means a loop to group, and another loop to display.
When grouping, I steal the ArtNo from the row of data and use it as the grouping key. The remaining data in the row will be an indexed subarray of that group/ArtNo.
I am going to show you some printf() and sprintf() syntax to keep things clean. printf() will display the first parameter's content and using any subsequent values to replace the placeholders in the string. In this case, the 2nd parameter is a conditional expression. On the first iteration of the group, ($i = 0), we want to show the ArtNo as the first cell of the row and declare the number of rows that it should span. sprinf() is just like printf() except it produces a value (silently). Upon any subsequent iterations of the group, $i will be greater than zero and therefore an empty string is passed as the value.
Next, I'm going to use implode() which is beautifully flexible when you don't know exactly how many columns your table will have (or if the number of columns may change during the lifetime of your project).
Tested Code:
$csv = <<<CSV
ABC237;Fingal Edition;48U;Nautical Blue;S - 5XL
ABC236;Fingal Edition;540;Navy;S - 5XL
ABC237;Fingal Edition;49U;Sea Foam;L - XL
ABC237;Fingal Edition;540;Navy;S - 5XL
CSV;
$lines = explode(PHP_EOL, $csv);
foreach ($lines as $line) {
$row = str_getcsv($line, ';');
$grouped[array_shift($row)][] = $row;
}
echo '<table>';
foreach ($grouped as $artNo => $group) {
foreach ($group as $i => $values) {
printf(
'<tr>%s<td>%s</td></tr>',
(!$i ? sprintf('<td rowspan="%s">%s</td>', count($group), $artNo) : ''),
implode('</td><td>', $values)
);
}
}
echo '</table>';
Output:
I have a csv file called data.csv.
Here's a sample of what's in data.csv
Microsoft,2020-02-13,"Sample",tt,aa,qq,w,ee,rr,tt,", ",", ",", ","2020-02-13 16:03:08"
Google,2020-02-13,"HQ",tt,aa,qq,w,ee,rr,tt,", ",", ",", ","2020-02-13 16:10:48"
I'm trying to iterate through each row of the csv and check if user inputted variable (lets say var="Microsoft") matches the first value in any row. If it does match, then return all the elements in that row as an array. (tried this using fgetcsv but returns whole csv file)
Here's what I have tried so far:
foreach ($csv as $line) {
if ($line[0] == 'Microsoft') {
$file = fopen("data.csv","r");
echo(fgetcsv($file));
fclose($file);
}
}
$csv = array_map('str_getcsv', file('./temp.csv'));
foreach ($csv as $line) {
if ($line[0] == 'Microsoft') {
echo implode(', ',$line);
}
}
If the first column's value is suitable as an array index. You can use array_column to re-index by your first column:
<?php
$result = array_column(array_map('str_getcsv', file('data.csv')), null, 0)['Microsoft'] ?? null;
I have a php page that is creating a csv file for download which is made up of an array.
Short version of Array:
$data = array("Joe Bloggs", "jbloggs", "John Doe", "jdoe")
My array is made from output from other commands so i cant just change the layout of my array, i can make two arrays, one for names and one for usernames if that help achieve my goal.
This is what i am doing to add the array values into my csv file:
$output = fopen('php://output', 'wb');
fputcsv($output, array('Name', 'Username'));
foreach ($data as $line ) {
$val = explode(",", $line);
for ($i=0; $i<$val["count"]; $i++); {
fputcsv($output , array($val[$i]));
}
}
fclose($output);
This gives me a csv that looks like this:
Name | Username
Joe Bloggs|
jbloggs |
John Does |
jdoe |
Really i need to have the usernames on the same row but in the username column.
I have tried this and lots of variations on this but it does not seem to work, my thinking was i increase N by two each time so $i will be the name because it is every other index position and then when doing the fputcsv it would add 1 to $i so it would grab the username as it is the value after the name.
foreach ($data as $line ) {
$val = explode(",", $line);
for ($i=0; $i<$val["count"]; $i+=2); {
fputcsv($output , array($val[$i], $val[$i+1]));
}
}
fclose($output);
Using the above gives me all the values in column one still.
Apologies for the write my code style question but i am out of my depth on this and cant find how to get to two consecutive values in a for loop of an array.
Here is 1 way of doing it.
$output = fopen('php://output', 'wb');
fputcsv($output, array('Name', 'Username'));
$temp = []; //Define a temp array.
foreach ($data as $line ) {
$temp[]= $line;
if( count( $temp) == 2 ) { //If no. of values in temp array is 2, write to csv file
fputcsv($output , $temp );
$temp = []; //initialize $temp;
}
}
fclose($output);
You can use simply these two line codes.
for ($i=0 ;$i < count($data);$i+2) {
fputcsv($output , $data[$i],$data[$i+1]);
}
I would like to count rows of text file (.txt) after specific row.
Example: I want after row 10 then row 11 until end will be count.
Is it possible?
What I've tried:
$files = "log.txt";
echo count(file($files));
But as you know it will count all rows.
What I want is, after row 10 then row 11 until end will be count.
Any idea?
UPDATE
Need to count only row with values, ignore for empty row/line
Try this
$files ="log.txt";
$f = fopen($files, 'rb');
$row = 1;
while (!feof($f)) {
$row += substr_count(fread($f, 8192), "\n");
}
fclose($f);
echo $row;
this if empty line is not counted
$r = array_filter(array_map("trim", file($files)), "strlen");
echo count($r);
Similar to markatonay but shorter:
$text = file_get_contents('/tmp/log.txt');
$lines = array_filter(array_map('trim', explode("\n", $text)));
print_r($lines);
echo "COUNT:" . count($lines);
echo "\r\n";
I'm trying to figure out how parse a multidimensional array/loop statement to lay out the iterated array values into rows (which will become a full row in a CSV file) The CSV file will end up with 24 rows based on below example
result
1999,apple,red
1999,apple,green
1999,orange,red
1999,orange,green
1999,strawberrry,red
... and so on
$year = array('1999','2000','2001','2002');
$fruit = array('apple','orange','strawberry');
$color = array('red','green');
You can use a foreach() loop and iterate over each of the 3 arrays and use fputcsv() to save the 3 items into a CSV file.
$fp = fopen('file.csv', 'w');
$year = array('1999','2000','2001','2002');
$fruit = array('apple','orange','strawberry');
$color = array('red','green');
foreach ($year as $y) {
foreach ($fruit as $f) {
foreach($color as $c) {
echo "$y,$f,$c" . PHP_EOL; // Echo to screen. Not needed
fputcsv($fp,array($y,$f,$c)); // Save each row to CSV file
}
}
}
fclose($fp);
Resulting file.csv file will then look like so:
