Loop into CSV file and get specific values from headers PHP - php

Question

I'm trying to import CSV file in order to automate the candidacies insertion.
As a first step, the user imports an excel file (.xls, .xls). From file, I convert it to csv in order to exploit it better thanks to PhpSpreadSheet library.
Example of csv file :
I would like to recover only some data columns, like lastName, firstName, gender, phonenumber .
For that, I'm using regular expressions to detect them. In every detection, I store the result in array.
However afterward, how can I recover data from these columns ?
$headers = [];
if(($handle = fopen($loadedSheetName.'.csv', "r")) !== FALSE)
{
foreach (fgetcsv($handle, 1000, ';') as $key => $header)
{
if (preg_match('/^(lastName)/i', $header, $matches))
{
$headers[$key] = $header;
}
if (preg_match('/^(firstName)/i', $header, $matches))
{
$headers[$key] = $header;
}
if (preg_match("/^(gender)/i", $header, $matches))
{
$headers[$key] = $header;
}
if (preg_match("/^(phoneNumber)/i", $header, $matches))
{
$headers[$key] = $header;
}
}
$keys = array_keys($headers);
$values = array_values($headers);
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)
{
$num = count($data);
for ($c=0; $c < $num; $c++)
{
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}

<?php
$headers = [];
$skip_headers = Array('lastname', 'firstname', 'gender', 'phonenumber');
if(($handle = fopen($loadedSheetName.'.csv', "r")) !== FALSE)
{
foreach (fgetcsv($handle, 1000, ';') as $key => $header)
{
if (!in_array(strtolower($header), $skip_headers))
{
$headers[$key] = $header;
}
}
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)
{
foreach ($headers as $key_ => $value)
{
echo $data[$key_] . "<br />\n";
}
}
fclose($handle);
}
