How Can I Efficiently Remove Invisible Line Breaks from a String?

Removing Line Breaks from Strings without Characters

In situations where user input contains line breaks without visible characters, standard methods like nl2br() may not suffice. To address this issue, we present a cleaner approach that preserves the original line break placement:

To remove line breaks from a string, use str_replace():

$buffer = str_replace(array("\r", "\n"), '', $buffer);

Advantages of this approach:

  • Efficient: str_replace() is significantly faster than preg_replace() for this task.
  • Eco-friendly: Using less CPU power reduces carbon dioxide emissions.

Understanding the Code:

The code uses str_replace() with two parameters:

  • array("r", "n"): An array of line break characters.
  • '': An empty string, effectively removing these characters from the $buffer string.
