How Can I Efficiently Replace Newlines with Single Spaces in a String using Regex?

Stripping Newlines and Replacing Them with Single Spaces

You have a string with line breaks and want to eliminate them, replacing them with a single empty space. To accomplish this, you've crafted a regex:

/\r\n|\r|\n/

But you're uncertain of the appropriate function to employ.

Let's dive into a solution that efficiently handles this task:

$string = trim(preg_replace('/\s\s+/', ' ', $string));

This regex effectively matches and replaces multiple spaces and newlines with a single space, ensuring a clean and consistent string.

Addressing Double Line Breaks

Originally, our regex might have left you with double spaces in cases of double line breaks. To rectify this, consider the following modified regex:

$string = trim(preg_replace('/\s+/', ' ', $string));

This modification ensures that all consecutive spaces, regardless of their count, are replaced with a single space.

Handling Single Newlines

While our solution handles most scenarios, it might encounter issues with single newlines occurring midway through words. If such a situation arises, you can opt for the following alternative:

$string = trim(preg_replace('/\n+/', ' ', $string));

This regex specifically targets newlines and replaces them with spaces, addressing the aforementioned issue.
