Are there specific considerations for handling large files in PHP scripts?

When handling large files in PHP scripts, it's important to consider memory usage and execution time. One way to handle large files efficiently is to read and process them in chunks rather than loading the entire file into memory at once. This can help prevent memory exhaustion and improve performance. 

$filename = 'large_file.txt';
$chunkSize = 1024; // 1 KB

$handle = fopen($filename, 'r');
if ($handle) {
    while (!feof($handle)) {
        $chunk = fread($handle, $chunkSize);
        // Process the chunk here
    }
    fclose($handle);
}
