wordwrap() requires one argument, the string to be transformed. : wordwrap String PHP
By default, wordwrap() wraps lines every 75 characters and uses n as its line-break character. <?php $string = "this is a test.this is a test.this is a test.this is a test.this is a test.this is a test."; $string .= "this is a test.this is a test.this is a test.this is a test.this is a test.this is a test."; print wordwrap($string); ?>
wordwrap() has two more optional arguments: a number representing the maximum number of characters per line and a string representing the end of the line string. : wordwrap String PHP
<?php print wordwrap( $string, 24, "<br/>n"); ?>
