How can PHP developers efficiently handle empty elements in arrays when processing text files?

When processing text files in PHP, empty elements in arrays can be efficiently handled by using the array_filter() function. This function will remove any empty elements from the array, allowing developers to work with a clean set of data. 

// Read the contents of a text file into an array
$lines = file('example.txt', FILE_IGNORE_NEW_LINES);

// Remove empty elements from the array
$lines = array_filter($lines);

// Loop through the array and process each line
foreach ($lines as $line) {
    // Process each line of text
    echo $line . "\n";
}
