What is the significance of using the FILE_IGNORE_NEW_LINES flag when reading lines from a file into an array in PHP?

The FILE_IGNORE_NEW_LINES flag is significant when reading lines from a file into an array in PHP because it prevents newline characters from being included in the array elements. This is useful when you want to process the lines without having to trim each element to remove the newline character.

// Read lines from a file into an array without including newline characters
$lines = file('file.txt', FILE_IGNORE_NEW_LINES);
