PHP probleme while remove columns in csv - php

Question

I use the php script below to remove some columns from a csv, order them new and save it as new file.
And it works for the file i made it for.
Now i need to do the same with another csv but i don't know whats wrong. I always get a comma befor the data in the first column.
This is what i have, but it doesn't really work.
<?php
$input = 'http://***/original.csv';
$output = 'new.csv';
if (false !== ($ih = fopen($input, 'r'))) {
$oh = fopen($output, 'w');
while (false !== ($data = fgetcsv($ih))) {
// this is where you build your new row
$outputData = array($data[4], $data[0]);
fputcsv($oh, $outputData);
}
fclose($ih);
fclose($oh);
}
The original.csv looks that:
subproduct_number barcode stock week_number qty_estimate productid variantid
05096470000 4024144513543 J 3 6 35016
ae214 848518017215 N 23 0 7 35015
05097280000 4024144513727 J 1 32 34990
The seperator is ';'. The same seperator is used in the file that is working
But here it will be go wrong because my saved new.csv looks like this:
subproduct_number barcode stock week_number qty_estimate productid variantid
,05096470000 4024144513543 J 3 6 35016
,ae214 848518017215 N 23 0 7 35015
,05097280000 4024144513727 J 1 32 34990
But what i need is a new csv that looks like this:
qty_estimate subproduct_number
3 05096470000
0 ae214
1 05097280000
As you can see, i need only the 5. column ($data[4]) as first and the first column ($data[0]) as the second one.
I hope someone can point me in the reight direction.
Thanks

You can do so:
while (false !== ($data = fgetcsv($ih))) {
$data = explode(';', $data[0]);
$outputData = array($data[4], $data[0]);
fputcsv($oh, $outputData, ';');
}
