How to count non-empty entries in a PHP array?
(5 answers)
Closed last year.
I have one CSV file. It contains 3 columns I want to count only the 3rd column total rows. I tried with one code but It showed the whole CSV file rows counts.
$record = file('filename.csv', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
$total_record = count($record);
echo $total_record; // output 6
As per the below image, I want to count only the Ph_no column. Please help me out

Answer 1

You could use array_map() to run callback str_getcsv() on each element (row) in the array that is returned by file().
$arr = array_map('str_getcsv', file('./filename.csv'));
The result ($arr) would look something like this:
Array
(
[0] => Array
(
[0] => First_Name
[1] => Last_name
[2] => Ph_no
)
[1] => Array
(
[0] => ABC
[1] => AB
[2] => 1234567890
)
... etc.
You can then count the number of phone numbers:
$phNo = array_column($arr, 2);
$phNoCount = count($phNo) -1 ; // subtract the header
echo 'Ph_no count: ' . $phNoCount;

$file = fopen('myCSVFile.csv', 'r');
$count = 0;
while (($line = fgetcsv($file)) !== FALSE) {
$num = count($line);
for ($i=0; $i < $num; $i++) {
if(!empty($line[2]) {
$count++;
}
}
}
fclose($file);
echo $count;

Answer 3

Using the fgetcsv() function it is quite simple
$tot = 0;
if (($f = fopen("filename.csv", "r")) !== FALSE) {
// read and ignore first line, titles
fgetcsv($f, 1000, ",");
while (($line = fgetcsv($f, 1000, ",")) !== FALSE) {
if ( $line[2] !== '' ) {
$tot += $line[2]; // accumulate column 3
}
}
}
fclose($f);
echo $tot;
