How Can I Efficiently Remove Line Breaks from a String Without Using Regular Expressions?

Removing Line Breaks from Strings Without Characters

In this question, a user seeks to remove line breaks from a string obtained from user input. The user clarifies that there are no end-of-line characters (n, r) present in the string.

Ben's Solution Using preg_replace()

One suggested solution is to use preg_replace() with an empty replacement string. However, this approach is relatively slower compared to str_replace(). Here's the code:

$buffer = preg_replace('/[\n\r]/m', '', $buffer);

Optimized Solution Using str_replace()

A more efficient alternative is to use str_replace() with an empty replacement string as shown below:

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

This method outperforms preg_replace() in terms of speed and efficiency. It does not require the use of a regular expression, which is more computationally intensive.

Environmental Impact

By using the optimized str_replace() solution, you can reduce the CPU power required to process the string. This, in turn, contributes to a reduction in carbon dioxide emissions from server operations.
