Recipe 1.13 Wrapping Text at a Certain Line Length
1.13.1 Problem
You need to wrap lines in a
string. For example, you want to display text in
<pre>/</pre> tags
but have it stay within a regularly sized browser window.
1.13.2 Solution
Use wordwrap( ):
$s = "Four score and seven years ago our fathers brought forth on this continen
t a new nation, conceived in liberty and dedicated to the proposition that all
men are created equal.";
print "<pre>\n".wordwrap($s)."\n</pre>";
<pre>
Four score and seven years ago our fathers brought forth on this continent
a new nation, conceived in liberty and dedicated to the proposition that
all men are created equal.
</pre>
1.13.3 Discussion
By default, wordwrap( ) wraps text at 75
characters per line. An optional second argument specifies different
line length:
print wordwrap($s,50);
Four score and seven years ago our fathers brought
forth on this continent a new nation, conceived in
liberty and dedicated to the proposition that all
men are created equal.
Other characters besides
"\n" can be used for linebreaks.
For double spacing, use "\n\n":
print wordwrap($s,50,"\n\n");
Four score and seven years ago our fathers brought
forth on this continent a new nation, conceived in
liberty and dedicated to the proposition that all
men are created equal.
There is an optional fourth argument to wordwrap(
) that controls the treatment of words that are longer than
the specified line length. If this argument is 1, these words are
wrapped. Otherwise, they span past the specified line length:
print wordwrap('jabberwocky',5);
print wordwrap('jabberwocky',5,"\n",1);
jabberwocky
jabbe
rwock
y
