PHP CSV File Stop on Blank Lines - php

Question

I'm trying to process an uploaded CSV file into an array in PHP. I have that working fine, but some files from users end up have a bunch of blank rows with delimiters. This usually happens when they use Excel on an existing file. Highlighting the old cells and just clearing them.
Sample CSV File
lineNo,date,vendor,amount
1,5/2/2012,V000236,3727.21
2,5/2/2012,V003432,4826.19
,,,
,,,
Becomes the following array
Array
(
[0] => Array
(
[0] => lineNo
[1] => date
[2] => vendor
[3] => amount
)
[1] => Array
(
[0] => 1
[1] => 5/2/2012
[2] => V000236
[3] => 3727.21
)
[2] => Array
(
[0] => 2
[1] => 5/2/2012
[2] => V003432
[3] => 4826.19
)
[3] => Array
(
[0] =>
[1] =>
[2] =>
[3] =>
)
[4] => Array
(
[0] =>
[1] =>
[2] =>
[3] =>
)
)
I don't want to just remove any blank rows, I want to stop after array index 2. Go easy on my function I'm new :P
function csvToArray($csvFile, $specialChars = FALSE) {
$arrayCSV = array();
if (($csvHandle = fopen($csvFile, "r")) !== FALSE) { // Open the CSV
$csvKey = 0; // Set the parent array key to 0
while (($csvData = fgetcsv($csvHandle)) !== FALSE) {
$c = count($csvData); // Count the total keys in each row
//need something to stop on blank delimiter rows ,,,
for ($x = 0; $x < $c; $x++) { //Populate the array
if ($specialChars === TRUE) {
$arrayCSV[$csvKey][$x] = htmlspecialchars($csvData[$x]);
} else {
$arrayCSV[$csvKey][$x] = $csvData[$x];
}
}
$csvKey++;
}
fclose($csvHandle);
}
return $arrayCSV;
}
Ultimately, I'd like this returned
Array
(
[0] => Array
(
[0] => lineNo
[1] => date
[2] => vendor
[3] => amount
)
[1] => Array
(
[0] => 1
[1] => 5/2/2012
[2] => V000236
[3] => 3727.21
)
[2] => Array
(
[0] => 2
[1] => 5/2/2012
[2] => V003432
[3] => 4826.19
)
)

Answer 1

Can't you break; your while loop as soon as you find an empty value?
if (($csvHandle = fopen($csvFile, "r")) !== FALSE) { // Open the CSV
$csvKey = 0; // Set the parent array key to 0
while (($csvData = fgetcsv($csvHandle)) !== FALSE) {
$c = count($csvData); // Count the total keys in each row
// ## Flag variable ##########
$empty = true;
for ($x = 0; $x < $c; $x++) { //Populate the array
// ## Test each value ##########
$empty = $empty && (empty($csvData[$x]));
if ($specialChars === TRUE) {
$arrayCSV[$csvKey][$x] = htmlspecialchars($csvData[$x]);
} else {
$arrayCSV[$csvKey][$x] = $csvData[$x];
}
}
// ## Stop loop if all empty ##########
if ($empty) {
unset($arrayCSV[$csvKey]);
break;
}
$csvKey++;
}
fclose($csvHandle);
}

Answer 2

Note:
A blank line in a CSV file will be returned as an array comprising a single null field, and will not be treated as an error.
if ($c == 1 && current($csvData) === null) {
break;
}

Answer 3

You can run a extra loop for checking empty
while(! feof($file)){
$current_data = fgetcsv($file);
for ($i=0; $i < $total_title ; $i++) {
if( empty( $current_data[ $i ] ) ){
unset($information[$itt]);
break;
}
$information[$itt][ $titles[$i] ] = $current_data[$i] ;
}
$itt = $itt+1;
}

I recommend this php function that does exactly what you want
