There are three single dimensional arrays that needs to be saved in csv
$arr1=array(1,2,3);
$arr2=array('a','b','c');
$arr3=array('x','y','z');
I need to save the above arrays in the csv like the following example-
1,a,x
2,b,y
3,c,z
I have tried the following code but its not saving in that format
$handle = fopen('file.csv', 'w');
$data=array($arr1,$arr2,$arr3);
foreach ($data as $line) {
fputcsv($handle, $line);
}
fclose($handle);
Output
1,2,3
a,b,c
x,y,z

Answer 1

Transpose the data before writing to the CSV
$data = array($arr1,$arr2,$arr3);
$transposedData = call_user_func_array(
'array_map',
array_merge(
array(NULL),
$data
)
);
$handle = fopen('file.csv', 'w');
foreach ($transposedData as $line) {
fputcsv($handle, $line);
}
fclose($handle);

Answer 2

foreach ($arr1 as $key => $value) {
fputcsv($handle, array($value, $arr2[$key], $arr3[$key]));
}

Answer 3

try like below:-
$arr1=array(1,2,3);
$arr2=array('a','b','c');
$arr3=array('x','y','z');
$handle = fopen('file.csv', 'w');
for($i=0; $i<count($arr1); $i++) {
$data=array($arr1[$i],$arr2[$i],$arr3[$i]);
fputcsv($handle, $data);
}
fclose($handle);
output
1 a x
2 b y
3 c z

Answer 4

Try this,Just take the transpose of the array before fputcsv
<?php
$arr1=array(1,2,3);
$arr2=array('a','b','c');
$arr3=array('x','y','z');
$data=array($arr1,$arr2,$arr3);
$rows = count($data);
$cols = count($data[0]);
$ridx = 0;
$cidx = 0;
$out = array();
foreach($data as $rowidx => $row){
foreach($row as $colidx => $val){
$out[$ridx][$cidx] = $val;
$ridx++;
if($ridx >= $rows){
$cidx++;
$ridx = 0;
}
}
}
$handle = fopen('file.csv', 'w');
foreach ($out as $line) {
fputcsv($handle, $line);
}
fclose($handle);
?>
Output
1,a,x
2,b,y
3,c,z

Answer 5

<?php
$arr1=array(1,2,3);
$arr2=array('a','b','c');
$arr3=array('x','y','z');
$output = '';
$data=array($arr1,$arr2,$arr3);
$size=count($data[0]);
//all arrays must have the same size! and $data must contain at least one item
for ($i = 0; $i < $size; $i++) {
foreach ($data as $arr) {
$output .= $arr[$i] . ';';
}
$output .= "\n";
}
file_put_contents($output);
?>
Expected output:
1;a;x;
2;b;y;
3;c;z;
