2 You have to be cautious of double line breaks, which would cause double spaces. Use this really efficient regular expression:
Multiple spaces and newlines are replaced with a single space. Edit: As others have pointed out, this solution has issues matching single newlines in between words. This is not present in the example, but one can easily see how that situation could occur. An alternative is to do the following:

PCRE regex replacements can be done using preg_replace: http://php.net/manual/en/function.preg-replace.php
Would replace new line or return characters with a space. If you don't want
anything to replace them, change the 2nd argument to answered Sep 21, 2010 at 13:37

GDYGDY 2,7451 gold badge23 silver badges42 bronze badges 3 I was surprised to see how little everyone knows about regex. Strip newlines in php is
In perl
Meaning replace any newline character at the end of the line (for efficiency) - optionally preceded by a carriage return - with a space. \n or \015 is newline. \r or \012 is carriage return. ? in regex means match 1 or zero of the previous character. $ in regex means match end of line. The original and best regex reference is perldoc perlre, every coder should know this doc pretty well: http://perldoc.perl.org/perlre.html Note not all features are supported by all languages. answered Feb 10, 2017 at 13:54
