I have a CSV file with 2 columns, id and key. An extract is...
26,"test1
test2
test3
"
54,"test34
test52
test673
"
67,"test1
test2a
test333
"
I am trying to load this file into PHP and convert the second field (key) into a serialized array, I have this so far...
$filename = 'myfile.csv';
if (($h = fopen("{$filename}", "r")) !== FALSE) {
while (($data = fgetcsv($h, 1000, ",")) !== FALSE) {
var_dump($data[1]);
}
fclose($h);
}
I am now trying to loop through the lines in $data[1] to convert them into an array, but when I do a var_dump the new lines seems to have disapeard. Am i approaching this the correct way?
Not sure what you meant by a serialized array here but I assume you want to make your key to be in a single line like below. LET ME KNOW IF I AM WRONG. So lets try like this way-
<?php
$fp = fopen('file.csv', 'r');
$csvArray = array();
while ($row = fgetcsv($fp)) {
$csvArray[$row[0]] = preg_replace("/[\r\n]/"," ",$row[1]);
}
fclose($fp);
print_r($csvArray);
?>
Output:
Array
(
[26] => test1 test2 test3
[54] => test34 test52 test673
[67] => test1 test2a test333
)

How to count non-empty entries in a PHP array?

Closed last year.
I have one CSV file. It contains 3 columns I want to count only the 3rd column total rows. I tried with one code but It showed the whole CSV file rows counts.
$record = file('filename.csv', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
$total_record = count($record);
echo $total_record; // output 6
As per the below image, I want to count only the Ph_no column. Please help me out
You could use array_map() to run callback str_getcsv() on each element (row) in the array that is returned by file().
$arr = array_map('str_getcsv', file('./filename.csv'));
The result ($arr) would look something like this:
Array
(
[0] => Array
(
[0] => First_Name
[1] => Last_name
[2] => Ph_no
)
[1] => Array
(
[0] => ABC
[1] => AB
[2] => 1234567890
)
... etc.
You can then count the number of phone numbers:
$phNo = array_column($arr, 2);
$phNoCount = count($phNo) -1 ; // subtract the header
echo 'Ph_no count: ' . $phNoCount;
$file = fopen('myCSVFile.csv', 'r');
$count = 0;
while (($line = fgetcsv($file)) !== FALSE) {
$num = count($line);
for ($i=0; $i < $num; $i++) {
if(!empty($line[2]) {
$count++;
}
}
}
fclose($file);
echo $count;
Using the fgetcsv() function it is quite simple
$tot = 0;
if (($f = fopen("filename.csv", "r")) !== FALSE) {
// read and ignore first line, titles
fgetcsv($f, 1000, ",");
while (($line = fgetcsv($f, 1000, ",")) !== FALSE) {
if ( $line[2] !== '' ) {
$tot += $line[2]; // accumulate column 3
}
}
}
fclose($f);
echo $tot;
I have a csv file which Contains Trace Signals of Vibration Data.
Its Starts with an ISO 8601 Date 2017-01-31T16:16:21.000+01:00
then it have 1024 rows of data(512Hz 2Sec Signal). And then the next Trace signal which starts with the new Date but in the same file -.-.
2017-01-31T16:16:21.000+01:00
0,06;0,03;0,01
0,07;0,03;0,01
0,07;0,03;0,02
.... up to line 1025
2017-01-31T16:24:37.000+01:00
1,72;0,2;-0,9
1,48;0,39;-1,46
1,23;0,58;-1,67
0,99;0,76;-1,81
... up to line 2050
This file can contain much more than 2 traces, how can i pass this in seperated arrays ? i would prefer arrays like :
Array
(
[0] => Array
(
[Time] => 2017-01-31T16:16:21.000
[Data] => array ( [0] => 0,06;0,03;0,01
[1] => 0,07;0,03;0,01 etc..)
)
But I don't know how to loop through the file and explode by the datetime value and also use it. Other way was To read Firstline as Time and next 1024 rows by line and push it but how ?
You may run into problems as your array gets larger, but this is the approach:
$i = $j = 0;
if($handle = fopen('/path/to/file.csv', 'r')) {
while(($line = fgets($handle)) !== false) {
if($i % 1025 === 0) {
$j++;
$result[$j]['Time'] = $line;
} else {
$result[$j]['Data'][] = $line;
}
$i++;
}
}
Just loop through the file and test if it is the first line or one that is a multiple of 1026. If it is, then you are on a line with the time, if not it is the data.
I am trying to import a CSV for a shop, with a subset of data from an existing CSV file. I need to split one item from a column (column 3, category_id) that contains multiple comma-separated values, then combine it with one other column (Product_id) to produce multiple rows in the import CSV. See the following examples.
Original CSV
Product_id;article_id;category_id;
"1";"0001";"2,4,6"
Need it into a new CSV file
Product_id;category_id
"1";"2"
"1","4"
"1","6"
I tried just the fegetcsv function to read in the CSV and to printout the whole into an array but I have no idea what to do next.
<?php
$handle = fopen ("articles.csv","r");
while ( ($data = fgetcsv ($handle, 1000, ";")) !== FALSE ) {
$column3[] = $data[3];
}
fclose ($handle);
//edit:
print_r($column3);
?>
I get:
Array ([0] => category_id [1] => 1 [2] => 0001 [3] => 2,4,6
Quick and dirty:
$csvData = file('articles.csv');
$matches = array();
$output = "";
foreach($csvData as $csvLine) {
if(preg_match('/"(.+)";".+";"(.+)"/', $csvLine, $matches))
{
$numbers = explode(',', $matches[2]);
foreach($numbers as $number) {
$output .= "\"{$matches[1]}\";\"{$number}\"" . PHP_EOL;
}
}
}
I have several csv files that contain order information for products. My csv files look something like below:
order_number,sku,qty,price_per,total_price
12345,55555,25,4,100
12346,33333,10,5,50
12347,55555,20,4,80
I'm not having any trouble finding out the total_price for all transactions, but how can I find the totals on each product? I tried creating an array for each, but I can't figure out how to keep the sku and total_price elements bound together.
Update #2
Since I can't have an array with matching keys, and since I want to end up here anyway, how can I get an array like this:
Array(
[55555] => 180
[33333] => 50
)
If anyone has any ideas on how I can make this array that would be great. Thanks!
Update #1
Sorry, I spaced adding my code, here it is:
foreach($files as $file){
$fh = fopen($file, 'rb');
while($col = fgetcsv($fh)) {
$csv[] = $col;
$total = array($col[27])
}}
This will do what you want, i.e. create an array $totals which sums the totals over skus:
$totals = array();
foreach($files as $file) {
$fh = fopen($file, 'rb');
while($col = fgetcsv($fh)) {
$csv[] = $col;
$total = array($col[27])
$totals[$col[1]] += $col[27];
}
}
Current answers don't produce the array you're after:
Array(
[55555] => 100
[33333] => 50
[55555] => 80
)
Because this can't be done - 55555 can't be used as a key twice. An alternative would be to have an array of the form:
Array(
[12345] => array("sku"=>55555,"total_price"=>100),
[12346] => array("sku"=>33333,"total_price"=>50),
[12347] => array("sku"=>55555,"total_price"=>80),
)
This code produces the second array:
$trans = array();
foreach($files as $file){
$fh = fopen($file, 'rb');
while($col = fgetcsv($fh)) {
$trans[$col[0]] = array("sku"=>$col[0],"total_price"=>$col[27]);
}
}
Assuming $col[0] is order and $col[1] is sku.
I have a CSV file that I need to import into an associative array. The data looks like this:
"General Mills Cereal",http://sidom.com/dyn_li/60.0.75.0/Retailers/Saws/120914_20bp4_img_8934.jpg,$2.25,"9-17.12 oz., select varieties","Valid Sep 14, 2012 - Sep 20, 2012",Saws,"Grocery"
I wan to transform this data into an array where I can grab values like this:
$items[$row]['title'];
$items[$row]['imgurl'];
$items[$row]['itemprice'];
$items[$row]['itemsize'];
$items[$row]['expir'];
$items[$row]['storename'];
$items[$row]['storetype'];
Where the elements above correspond to my CSV file. How can I import this file into such an array?
I would suggest using the built-in function fgetcsv
There's a simple usage example there also.
fgetcsv() will give you a numerically indexed array.
Once you have read all records in to say $rawData, which has a structure along the lines of:
$rawData = array(0 => array(0 => "General Mills Cereal",
1 => "http://sidom.com/dyn_li/60.0.75.0/Retailers/Saws/120914_20bp4_img_8934.jpg"
2 => "$2.25",
3 => "9-17.12 oz.",
4 => "select varieties",
5 => "Valid Sep 14, 2012 - Sep 20, 2012",
6 => "Saws",
7 => "Grocery"),
...);
To convert this $rawData array to what you want, you can do something like this:
$fields = array('title', 'imgurl', 'itemprice', 'itemsize',
'expir', 'storename', 'storetype');
$data = array_map(function($cRow) uses ($fields) {
return array_combine($fields, $cRow);
}, $rawData);
See below URL
CSV to Associative Array
Try it
run over the csv file line by line, and insert to array like:
$array = array();
$handle = #fopen("file.csv", "r");
if ($handle) {
while (($line = fgetcsv($handle, 4096)) !== false) {
$array[$line[0]][$line[1]][$line[2]] = $line[3];
}
if (!feof($handle)) {
echo "Error: unexpected fgets() fail\n";
}
fclose($handle);
}
