Using PHP wordwrap() to Split Strings into Specified Lengths

The wordwrap() function in PHP breaks a given string into smaller chunks based on a specified width, optional break string, and an optional cut flag that forces splitting even within words.

Parameters:

str : the input string to be wrapped.

width : the maximum line width (number of characters).

break : the string inserted at each wrap point (default is "\n").

cut : boolean flag; when true, the string is cut at the exact width even if a word exceeds the limit.

Return value: the wrapped string with the chosen break characters inserted.

Example 1:

<?php
$text = "The quick brown fox jumped over the lazy dog.";
$newtext = wordwrap($text, 20, "<br />
");
echo $newtext;
?>

Output:

The quick brown fox<br />
jumped over the lazy<br />
dog.

Example 2 (cut enabled):

<?php
$text = "A very long woooooooooooord.";
$newtext = wordwrap($text, 8, "
", true);
echo $newtext;
?>

Output:

A very<br/>long<br/>wooooooo<br/>ooooord
