How Can I Replace All Newlines in a String with Single Spaces Using PHP?

Eliminating Newlines in Strings with a Single Space

Given a string with embedded newlines, the goal is to remove all occurrences of newlines and replace them with a single empty space. The provided regex effectively identifies all newlines, but the appropriate function to employ for this task eludes you.

Utilizing the powerful preg_replace() function, along with a tailored regular expression, can accomplish the desired result:

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

This regex matches consecutive spaces, including newlines, and replaces them with a single space. This ensures that multiple spaces or newlines are effectively collapsed into a single space.

Be aware of potential issues with double line breaks, which could result in double spaces. To address this, consider an alternative regex:

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

This regex matches all consecutive spaces, regardless of their origin, and replaces them with a single space, successfully removing all newlines and extra spaces.
