unable to write csv from array - php

Question

I read most of the discussions about my problem but I do not find a solution.
So, I have a .csv file from which I read, extract all the content and populate a multidimensional array. That is the code I wrote to do that:
if (($handle = fopen("dateRegion.csv", "r")) !== FALSE) {
# Set the parent multidimensional array key to 0.
$pr = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
# Count the total keys in the row.
$count = count($data);
# Populate the multidimensional array.
for ($x = 0; $x < $count; $x++) {
$brim[$pr][$x] = $data[$x];
}
$pr++;
}
fclose($handle);
}
After that, I extract the element I need and put it into another array. That array will be the content of the new .csv file.
This is the code:
$parserCsv = array();
$dip=1;
do {
$region = $brim[$dip][7];
$sex = $brim[$dip][8];
$frequency = $brim[$dip][9];
$value = $brim[$dip][10];
$parserCsv[] = array($region, $sex, $frequency, $value);
$dip++;
} while($dip <= 6336);
This is the "var_dump()" of the array:
Array(
[0] => Piemonte
[1] => maschi
[2] => 2005
[3] => 16.972)
etc.
I tried to put the content of the array $parserCsv using the method fputcsv(), with that script:
$fp = fopen('csvExtract.csv', 'w');
foreach ($parserCsv as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);
but it did not work. The content of the file csvExtract.csv is blank. I do not understand my mistake, I tried other solution like create the array $parserCsv like:
$parserCsv = array(
array($region), array($sex), array($frequency), array($value));
and nothing change. Does anyone have some advise?
EDIT: Edited the code with the solution suggested by mkjasinski! The code is working now.
Thanks for all the replies.

Try this:
if (($handle = fopen("dateRegion.csv", "r")) !== FALSE) {
# Set the parent multidimensional array key to 0.
$pr = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
# Count the total keys in the row.
$count = count($data);
# Populate the multidimensional array.
for ($x = 0; $x < $count; $x++) {
$brim[$pr][$x] = $data[$x];
}
$pr++;
}
fclose($handle);
}
and this:
$parserCsv = array();
$dip=1;
do {
$region = $brim[$dip][7];
$sex = $brim[$dip][8];
$frequency = $brim[$dip][9];
$value = $brim[$dip][10];
$parserCsv[] = array($region, $sex, $frequency, $value);
$dip++;
} while($dip <= 6336);
and save:
$fp = fopen('csvExtract.csv', 'w');
foreach ($parserCsv as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);

Answer 2

are you getting some errors?
Is the file open in some other software? (like MS Excel?)
Following code enters 4 records in CSV
$parserCsv = array(
array('Piemonte'),
array('maschi'),
array(2005),
array(16.972)
);
$fp = fopen('blah.csv', 'w');
foreach($parserCsv as $fields)
{
fputcsv($fp, $fields);
}
fclose($fp);
