How can one prevent or handle empty lines in a text file when using the explode function in PHP?

When using the explode function in PHP to split a string into an array based on a delimiter, empty lines in the text file can result in empty array elements. To prevent or handle empty lines, you can use array_filter() function to remove any empty elements from the resulting array before processing it further. 

// Read the contents of the text file into a string
$file_contents = file_get_contents('example.txt');

// Split the string into an array based on new line delimiter
$lines = explode("\n", $file_contents);

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

// Process the non-empty lines as needed
foreach ($lines as $line) {
    // Do something with each non-empty line
}
