Writing to multiple (splitting) CSV files with PHP - php

Question

I'm using a simple function to write write arrays to a CSV-file, which look like this:
function writeToCSV($array) {
$fp = fopen('programmes.csv', 'a');
fputcsv($fp, $array);
fclose($fp);
}
Simple as a pie. However, is there anyway to know what line-number the pointer is at? Because I want to be able to after 1000 lines to begin writing to a new file. Why? Because I need to be able to import them to a database later with some memory constraints, and to parse a CSV-file with 15000 lines is a no-no.

Answer 1

function writeToCSV($array) {
$i = 1;
$j = 1;
$fp = fopen('programmes' . $j . '.csv', 'a');
foreach($array as $fields) {
if ($i % 1000 == 0) {
fclose($fp);
$fp = fopen('programmes' . $j . '.csv', 'a');
$j = $j + 1;
}
fputcsv($fp, $fields);
$i = $i + 1;
}
fclose($fp);
}

Answer 2

Try this:
count(file('programmes.csv'));
This will give you the number of lines in a file.

Answer 3

I haven't tried if this works, but i would do something like this:
<?php
function writeToCSV($array) {
// count lines in the current file
$linecount = 0;
$fh = fopen('programmes.csv','rb') or die("ERROR OPENING DATA");
while (fgets($fh) !== false) $linecount++;
fclose($fh);
$aSize = sizeof($array);
if (($linecount + $aSize) > 1000) {
// split array
$limit = 1000 - $linecount;
$a = array_slice($array, 0, $limit);
$b = array_slice($array, $limit);
// write into first file
$fp = fopen('programmes.csv', 'a');
foreach($a as $field) fputcsv($fp, $field);
fclose($fp);
// write into second file
$fp = fopen('programmes2.csv', 'a');
foreach($b as $field) fputcsv($fp, $field);
fclose($fp);
} else {
$fp = fopen('programmes.csv', 'a');
$idx = 0;
while ($linecount < 1000) {
// fill the file to the 1000 lines
fputcsv($fp, $array[$idx]);
++$linecount;
++$idx;
}
fclose($fp);
if ($idx != $aSize) {
// create new file
$fp = fopen('programmes.csv', 'a');
while ($idx< $aSize) {
// fill the file to the 1000 lines
fputcsv($fp, $array[$idx]);
++$idx;
}
fclose($fp);
}
}
}
?>
