What potential issue could arise when reading a CSV file into a table using PHP?

One potential issue that could arise when reading a CSV file into a table using PHP is handling large files that may exceed memory limits. To solve this, you can use the `fgetcsv` function to read the file line by line instead of loading the entire file into memory at once. 

<?php

$filename = 'data.csv';
$delimiter = ',';
$header = NULL;
$data = [];

if (($handle = fopen($filename, 'r')) !== FALSE) {
    while (($row = fgetcsv($handle, 1000, $delimiter)) !== FALSE) {
        if (!$header) {
            $header = $row;
        } else {
            $data[] = array_combine($header, $row);
        }
    }
    fclose($handle);
}

print_r($data);

?>
