<font color="#0000BB">&lt;?php phpinfo</font><font color="#007700">(); </font><font color="#0000BB">?&gt;</font>
</font>

<code><span style="color: #000000">
<span style="color: #0000BB">&lt;?php phpinfo</span><span style="color: #007700">(); </span><span style="color: #0000BB">?&gt;</span>
</span>
</code>

Notes

Note:

When the return parameter is used, this function uses internal output buffering so it cannot be used inside an ob_start() callback function.
