Word wrap in PHP

Word wrap in PHP

Did you know that doing word wrap in PHP is really really easy? It seems that starting PHP version 4.0.2 there is a function called "wordwrap" that does this thing.

It accepts 4 parameters (one required and 3 optional) :

• text to wrap (required)
• width of a line (optional, default is 75 characters)
• new line separator (optional, default is "n", for HTML output use "<br />")
• cut long words? set to true if you want to cut into words (optional, default is false)

Here are some usage examples :

$test = 'CodePax is a great learning resource.';
 
//word wrap at 10 characters
$new1 = wordwrap($test,10);
 
//word wrap at 4 characters, separate lines by '-'
$new2 = wordwrap($test,4,'-');
 
//word wrap at 4 characters, separate lines by '-' but also break longer words
$new3 = wordwrap($test,4,'-',true);

and the output of the code above :

$new1 will contain : 
CodePax is
a great
learning
resource.
 
 
$new2 will contain :
CodePax-is a-great-learning-resource.
 
 
$new3 will contain : 
Code-Pax-is a-grea-t-lear-ning-reso-urce-
