highlight_string

(PHP 4, PHP 5)

highlight_string -- Syntax highlighting of a string

Description

mixed highlight_string ( string str [, bool return] )

The highlight_string() function outputs a syntax highlighted version of str using the colors defined in the built-in syntax highlighter for PHP.

If the second parameter return is set to TRUE then highlight_string() will return the highlighted code as a string instead of printing it out. If the second parameter is not set to TRUE then highlight_string() will return TRUE on success, FALSE on failure.

Note: This function internally uses the output buffering with this parameter so it can not be used inside ob_start() callback function.

Example 1. highlight_string() example

<?php
highlight_string('<?php phpinfo(); ?>');
?>

The above example will output (in PHP 4): 

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

The above example will output (in PHP 5): 

<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>

Note: The return parameter became available in PHP 4.2.0. Before this time it behaved like the default, which is FALSE
