It is suitable for more complex strings, generating HTML strings or XML or other functions. It will treat each line as each line of text. However, in some special cases, it cannot be seen but the real existence, such as HTML code, will be ignored. Line break


Symbol:
<<<

Syntax:

<code><<<变量(无<span>$符</span>)
(开头无空格)第一行 
<span>XXX</span><span>XXX</span><span>XX</span>(开头无空格)变量(无<span>$符</span>)</code>
<code><span><span><?php</span><span>$s</span> =<span><<<s
<p>1</p>
<p>2</p>
<p>3</p>
s;<span>echo</span><span>$s</span>;
<span>?></span><pre class="brush:php;toolbar:false"><code>1

2

3</code>

Example 2:

<code><span><?php</span><span>$_data</span> =<span><<<data
<?xml version="1.0" encoding="UTF-8"?>
<note>
    <to>George</to>
    <from>老三</from>
    <heading>Reminder</heading>
    <body>Don't forget the meeting!</body>
</note>
data;</span><span>$myfile</span> = fopen(<span>"file.txt"</span>, <span>"w"</span>) <span>or</span><span>die</span>(<span>"Unable to open file!"</span>); 
fwrite(<span>$myfile</span>, <span>$_data</span>);
fclose(<span>$myfile</span>);
<span>?></span></code>
<code>file.txt内容:
<span><?xml version="1.0" encoding="UTF-8"?></span><span><<span>note</span>></span><span><<span>to</span>></span>George<span></<span>to</span>></span><span><<span>from</span>></span>老三<span></<span>from</span>></span><span><<span>heading</span>></span>Reminder<span></<span>heading</span>></span><span><<span>body</span>></span>Don't forget the meeting!<span></<span>body</span>></span><span></<span>note</span>></span></code>
').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });
