Question

Imagine I have 150 characters long string. I would like to divide it into 3 parts, each max 50 characters long. The trick is I also have to keep words intact while dividing the string into 3 parts.

I could use substr and check if it cut the word into half or not. I would like to know if there is any other elegant way to do this.

I also have to keep it in mind that the string might have less than 150 characters. For example if it is 140 characters long then it should be 50 + 50 + 40.

In case if it is less than 100 than it should be 50 + 50. If it is 50 characters or less it shouldn’t divide the string.

I would be glad to hear your ideas / ways to approach this.

Thank you in advance for your time and concern.

Sounds like you just want the php function wordwrap()

 string wordwrap ( string $str [, int $width = 75 [, string $break = “\n” [, bool $cut = false ]]] )

Wraps a string to a given number of characters using a string break character.
