How can PHP developers optimize their code to prevent memory-related errors during file uploads?

PHP developers can optimize their code to prevent memory-related errors during file uploads by increasing the memory limit in the php.ini configuration file, using functions like `ini_set('memory_limit', '256M');` before the file upload process, and handling file uploads in chunks rather than loading the entire file into memory at once. 

// Set memory limit to 256MB
ini_set('memory_limit', '256M');

// Handle file upload in chunks
$chunkSize = 1024 * 1024; // 1MB chunk size
$filePath = 'path/to/uploaded/file';
$handle = fopen($filePath, 'rb');

while (!feof($handle)) {
    $chunk = fread($handle, $chunkSize);
    // Process the chunk here
}

fclose($handle);
