What are common challenges when parsing files in PHP and how can they be overcome?

One common challenge when parsing files in PHP is handling large files that may exceed memory limits. To overcome this, you can read the file line by line instead of loading the entire file into memory at once. 

$filename = 'large_file.txt';
$handle = fopen($filename, 'r');

if ($handle) {
    while (($line = fgets($handle)) !== false) {
        // Process each line here
    }

    fclose($handle);
} else {
    echo "Error opening file.";
}
