What are some strategies for efficiently handling memory usage when reading large or multiple files in PHP?

When reading large or multiple files in PHP, it's important to efficiently handle memory usage to prevent running out of memory. One strategy is to read files line by line instead of loading the entire file into memory at once. This can be achieved using functions like `fgets()` or `SplFileObject`. 

// Open the file for reading
$handle = fopen('large_file.txt', 'r');

// Read the file line by line
while (($line = fgets($handle)) !== false) {
    // Process each line here
}

// Close the file handle
fclose($handle);
