What are the best practices for checking and monitoring log files in PHP to diagnose issues like a white screen?

To diagnose issues like a white screen in PHP, it is important to check and monitor log files for any errors or warnings that may be causing the problem. One way to do this is by enabling error logging in PHP and setting the appropriate log level to capture any issues that may arise. Additionally, regularly monitoring these log files can help identify and troubleshoot any issues quickly. 

// Enable error logging in PHP
ini_set('display_errors', 0);
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Set the error reporting level to capture all errors
error_reporting(E_ALL);

// Check the error log file for any issues
$logFile = '/path/to/error.log';
if (file_exists($logFile)) {
    $logContent = file_get_contents($logFile);
    echo $logContent;
} else {
    echo 'No errors found in log file.';
}
