PHP wordwrap function

PHP wordwrap() function is used for wrapping a string to a given number of characters. It will cut the string at the specified length and insert the string or character we have entered at that position.

Its Syntax will be :
wordwrap ( string , length , break character , cut mode );

  • First parameter will be the string to be wrapped
  • Second parameter specifies at which length wrap should occur.
  • Third parameter specified the character or string to be inserted at the specified length.
  • Fourth parameter is optional. This cut mode parameter specified the mode of cutting. When we specify this parameter as TRUE , cutting will occur at the middle of words too , it will strictly cut at the specified length. By default its value will be false , and cutting wont happen in the middle of a word.

You will get more clear picture about this wordwrap function after seeing the following sample PHP programs and its output

<?php
$text="This tutorial will show about wordwrap function";
echo wordwrap($text,5," * ")
?>

Its output will be :

This * tutorial * will * show * about * wordwrap * function

Here we can see that single words are not splitted , they remains the same.

Now look at the next program with CUT mode parameter as TRUE

<?php
$text="This tutorial will show about wordwrap function";
echo wordwrap($text,5," * ", TRUE)
?>
Its output will be :

This * tutor * ial * will * show * about * wordw * rap * funct * ion

Here we can see that function has splitted the string strictly at the specified length and single words also splitted .
