How can one effectively process specific lines of text stored in an array after extracting them from a textarea in PHP?

When text is entered into a textarea and stored in an array in PHP, you may need to process specific lines of text individually. To do this, you can loop through the array and apply any necessary operations to each line. You can use functions like explode() to split each line into an array of words or preg_match() to extract specific patterns from each line. 

// Assuming $lines is an array containing text lines from a textarea
foreach ($lines as $line) {
    // Perform operations on each line here
    // For example, splitting the line into words
    $words = explode(' ', $line);
    
    // Or extracting specific patterns using regular expressions
    if (preg_match('/pattern/', $line)) {
        // Process the line further
    }
}
