Splitting array if empty value - php

Question

I am trying to split an array if one of the lines has an empty value. My array is being exported to a csv and has multiple lines of data, if the data is not complete it will be sent to a uncomplete csv and if it is complete it will be sent a complete csv.
This is what my array structure looks like the blank field on the first line is on email (this line should be split out of the array:
array(2) {
[0]=> array(6) {
["Username"]=> string(47) " STARRY NIGHT CINEMA - RISE OF THE GUARDIANS "
["Email"]=> string(0) ""
["Location"]=> string(1) "1"
["Type"]=> int(1)
["Title"]=> string(47) " STARRY NIGHT CINEMA - RISE OF THE GUARDIANS "
["Description"]=> string(491) "the Tooth Fairy"
}
[1]=> array(6) {
["Username"]=> string(26) "Maui Nui Botanical Gardens"
["Email"]=> string(18) "info#mnbg.org"
["Location"]=> string(1) "1"
["Type"]=> int(1)
["Title"]=> string(26) "Maui Nui Botanical Gardens"
["Description"]=> string(50) "Conserving Hawaiian Plants & Cultural Heritage"
}
}
Writing to my csv:
$fp = fopen('entries.csv', 'w');
foreach ($entries as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);
if (!copy("http://www.simonstaton.co.uk/entries.csv", "entries.csv")) {
echo ("failed to copy file");
};
I have no idea where to start with this and as to what function I should use so any advice is greatly appreciated.

Answer 1

To separate the entries by complete or incomplete you can open two files for writing. One to contain each.
// filenames
$fn_complete = 'entries.csv';
$fn_incomplete = 'incomplete_entries.csv';
// file pointers
$fp_complete = fopen($fn_complete, 'w');
$fp_incomplete = fopen($fn_incomplete, 'w');
// write CSVs
foreach ($entries as $fields) {
if (in_array('', $fields))
fputcsv($fp_incomplete, $fields);
else
fputcsv($fp_complete, $fields);
}
fclose($fp_complete);
fclose($fp_incomplete);
if (!copy('http://www.simonstaton.co.uk/' . $fn_complete, $fn_complete)) {
echo ('failed to copy file ' . $fn_complete);
};
if (!copy('http://www.simonstaton.co.uk/' . $fn_incomplete, $fn_incomplete)) {
echo ('failed to copy file ' . $fn_incomplete);
};

You can check if any of the values in your array is empty like this:
in_array('', $array)
so it then you can do a simple if
if(in_array('', $array)) {
//Do whatever you have to do to slip your array. I don't understand exactly what you want the end result to look like .
}

Answer 3

First pack your CSV data into an array using fgetcsv(). Then use a loop to search for "".
Exemplar:
$row = 1;
if (($resource = fopen("example.csv", "r")) !== false) {
while (($data = fgetcsv($resource, 1000, ",")) !== false) {
$num = count($data);
$row++;
for ($c=0; $c < $num; $c++) {
if ($data[$c] == "") {
// operate
}
}
}
fclose($handle);
}
By the way, don't use the split() function. Use preg_split().
