["Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:22, GENDER:MALE, Age:63,Bp_Systolic:120,Bp_Diastolic:80", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:27, GENDER:FEMALE, Age:56,Bp_Systolic:110,Bp_Diastolic:70", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:33, GENDER:MALE, Age:58,Bp_Systolic:130,Bp_Diastolic:70", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:48, GENDER:FEMALE, Age:62,Bp_Systolic:132,Bp_Diastolic:80", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:50, GENDER:MALE, Age:60,Bp_Systolic:120,Bp_Diastolic:70", "Boxname:MH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:51, GENDER:MALE, Age:63,Bp_Systolic:118,Bp_Diastolic:62"]

I want to convert this array into csv export file. I have tried code like this.

<?php
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=data.csv');

// create a file pointer connected to the output stream
$output = fopen('php://output', 'w');

// output the column headings
fputcsv($output, array('Column 1', 'Column 2', 'Column 3'));

$list=$name;
foreach ($list as $line)
  {
fputcsv($output, $line);
  }

?>

But i can t able to get the data. Can any body help me out. I have tried many ways. I think my array format giving trouble. Can anybody suggest array format from this to make the export easy.

Answer 1

You are passing a string of concatenated values as rows to fputcsv() where it expects an array element for each column. Your data should be split into an array of column values for each row, IE:

$list = Array(
    Array("Boxname:HH", "X1:53.3", "X2:106.6", "Y1:33.300000000000004", "Y2:59.947215189873425", "PID:22", "GENDER:MALE", "Age:63", "Bp_Systolic:120", "Bp_Diastolic:80"),
    Array("Boxname:HH", "X1:53.3", ..)
    //etc
)

Changing this array is how you are going to fix this. If you can't change the way the array is created, you can always remap it to have it in the format fputcsv() expects, using array_map() :

$list = ["Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:22, GENDER:MALE, Age:63,Bp_Systolic:120,Bp_Diastolic:80", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:27, GENDER:FEMALE, Age:56,Bp_Systolic:110,Bp_Diastolic:70", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:33, GENDER:MALE, Age:58,Bp_Systolic:130,Bp_Diastolic:70", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:48, GENDER:FEMALE, Age:62,Bp_Systolic:132,Bp_Diastolic:80", "Boxname:HH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:50, GENDER:MALE, Age:60,Bp_Systolic:120,Bp_Diastolic:70", "Boxname:MH, X1:53.3, X2:106.6, Y1:33.300000000000004,Y2:59.947215189873425, PID:51, GENDER:MALE, Age:63,Bp_Systolic:118,Bp_Diastolic:62"];

$list = array_map(function($i){
    return array_map("trim", // Trim the values
        explode(",", $i) // Explode each row into an array of column values
    );
}, $list);

header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=data.csv');

$output = fopen('php://output', 'w');

fputcsv($output, array('Column 1', 'Column 2', 'Column 3'));

foreach ($list as $line) {
    fputcsv($output, $line);
}

Answer 2

This is an example of a working solution, maybe you could use this as a base:

$maxSize = count($commentArray);

    for ($c=0; $c < $maxSize; $c++) {
        $toCSV .= $nameArray[$c] . ";" . $amountArray[$c] . ";" . $dateArray[$c] . ";" . $commentArray[$c] . ";" . $bankaccount[$c] . "\n";
    }

file_put_contents($file, $toCSV);       

It loops through all elements of the arrays, separates the values by ; s and when the final element is reached then it puts a new line separator.

Once this is concatenated as a whole, file_put_contents creates a CSV file.
