php add <br /> only after first 100 characters
<p>How to add <code>&lt;br /&gt;</code> only after first 100 characters? I mean just break once, not add <code>&lt;br /&gt;</code> after each 100 characters.</p>

<pre><code>$str="Apple has announced that co-founder, former CEO and chairman of the board Steve Jobs has passed away at the age of 56, so we take a look back at the famous innovator's life.At left, Steve Jobs, chairman of the board of Apple Computer, leans on the new 'Macintosh' personal computer following a shareholder's meeting Jan. 24, 1984, in Cupertino, Calif. The Macintosh was priced at $2,495.";
//echo substr($str, 0, 100).'&lt;br /&gt;'; this will break sentence after 100 characters. 
//echo wordwrap($str, 100, "\n&lt;br /&gt;\n");this will add &lt;br /&gt; after each 100 characters.
</code></pre>

<p>And what I need is:</p>

<pre><code>Apple has announced that co-founder, former CEO and chairman of the board Steve Jobs has passed away    
&lt;br /&gt; &lt;-- only add here.
at the age of 56, so we take a look back at the famous innovator's life.At left, Steve Jobs, chairman of the board of Apple Computer, leans on the new 'Macintosh' personal computer following a shareholder's meeting Jan. 24, 1984, in Cupertino, Calif. The Macintosh was priced at $2,495.
