What potential issues can arise when using fgetcsv to read a large CSV file and writing to a MySQL database in PHP?

One potential issue that can arise when using fgetcsv to read a large CSV file and writing to a MySQL database in PHP is memory consumption. Reading a large CSV file into memory can lead to high memory usage, potentially causing performance issues or even running out of memory. To solve this issue, you can process the CSV file line by line instead of loading the entire file into memory at once. 

<?php
$csvFile = 'large_file.csv';
$handle = fopen($csvFile, 'r');
if ($handle !== false) {
    while (($data = fgetcsv($handle)) !== false) {
        // Process each row of data and insert into MySQL database
        // Example: $data[0] is the first column, $data[1] is the second column, etc.
    }
    fclose($handle);
} else {
    echo "Error opening file.";
}
?>
