How to use fgetcsv to get specific columns from a CSV? - php

Question

I have an interesting piece of work to complete
I have a lot of spreadsheets which I have converted to CSV's - these spreadsheets started out as templates with a set number of columns.
Unfortunately over time people have added columns and removed them.
Is there a way I can adapt the following code to select certain column names from each CSV
foreach($fileinfos as $pathname => $fileinfo) {
if (!$fileinfo->isFile()) continue;
if(substr($pathname,-3) == 'csv'){
$file = fopen($pathname, "r");
while ($line = fgetcsv($file,0,'^','¬')){
echo substr($pathname,56) .' '.$numcols.'<br>';
}
fclose($file);
}
}
UPDATE:
Here is my array of accepted columns
Array
(
[0] => Date Raised
[1] => QA phase
[2] => Item ID
[3] => Screen Number
[4] => Reason
[5] => Matches originals?
[6] => Issue / Comments
[7] => Raise with Client?
[8] => Raised By
[9] => Status
[10] => TP/AS Status Initials
[11] => TP/AS Status date
[12] => TP/AS Status Comment
[13] => Retested by
[14] => Retested date
[15] => Retested Comment
)

Answer 1

$file = fopen($pathname, 'r');
$headers = fgetcsv($file, 0, '^', '¬');
while ($line = fgetcsv($file, 0, '^', '¬')) {
$line = array_combine($headers, $line);
var_dump($line);
// access specific fields using $line['columnName']
}

Answer 2

I would try something like this:
$csv = array();
$columnnames = fgetcsv($fp, 1024);
while (true == ($columns = fgetcsv($fp, 1024))) {
$row = array_combine($columnnames, $columns);
$csv[] = $row;
}
On a CSV file like this
id,name,email
1,benjamin,benjamin#example.com
2,rob,rob#example.com
the $csv variable should contain something like this:
1 => array(
'id' => 1,
'name' => 'benjamin',
'email' => 'benjamin#example.com'
)
...
