$string = " put returns between paragraphs for linebreak add 2 spaces at end "; Want to remove all new lines from string.
I've this regex, it can catch all of them, the problem is I don't know with which function should I use it.
/\r\n|\r|\n/ $string should become:
$string = "put returns between paragraphs for linebreak add 2 spaces at end ";

The strip() method in-built function of Python is used to remove all the leading and trailing spaces from a string. Our task can be performed using strip function() in which we check for “\n” as a string in a string.
trim method removes any line breaks from the start and end of a string. It handles all line terminator characters (LF, CR, etc). The method also removes any leading or trailing spaces or tabs. The trim() method doesn't change the original string, it returns a new string.
You have to be cautious of double line breaks, which would cause double spaces. Use this really efficient regular expression:
$string = trim(preg_replace('/\s\s+/', ' ', $string)); 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:
$string = trim(preg_replace('/\s+/', ' ', $string)); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
