Newline inside variable string

rated 0 times [ 164] [ 6] / answers: 1 / hits: 18270 / 12 Years ago, sat, march 10, 2012, 12:00:00

What if I have a long input of string? maybe 50-250 characters.
and I echoed the variable it would echo a very long line of letters and words.

So, how will I let the variable auto Newline itself? maybe after 50 characters it would new line when echoed.

I have thought of counting the length of the string and looping it and after counting 50 characters it would Newline but if i do that it would slow down the Site.

is there any function to Newline a VARIABLE STRING? or i should use Looping instead?

You can use a built-in PHP function: wordwrap.

If you want to cut at 50 characters and insert a HTML line-break:
wordrap($str, 50, <br />);
You can also use the last parameter to force return, even if the string does not contain spaces.
