What are some common methods in PHP to read and parse log files for specific data extraction?

Reading and parsing log files in PHP can be done using various methods such as file_get_contents, fopen, or libraries like SplFileObject. Once the log file is read, regular expressions or string manipulation can be used to extract specific data from the log entries. 

// Example code to read and parse a log file for specific data extraction
$logFile = 'path/to/logfile.log';
$logData = file_get_contents($logFile);

// Extract specific data using regular expressions
preg_match('/Error: (.*)/', $logData, $matches);
$errorMessages = $matches[1];

echo $errorMessages;
