highlight_string

(PHP 4, PHP 5, PHP 7)

highlight_string — Syntax highlighting of a string

Description

highlight_string ( string $str [, bool $return = FALSE ] ) : mixed

Outputs or returns html markup for a syntax highlighted version of the given PHP code using the colors defined in the built-in syntax highlighter for PHP.

Parameters

str: The PHP code to be highlighted. This should include the opening tag.
return: Set this parameter to TRUE to make this function return the highlighted code.

Return Values

If return is set to TRUE, returns the highlighted code as a string instead of printing it out. Otherwise, it will return TRUE on success, FALSE on failure.

Examples

Example #1 highlight_string() example

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

The above example will output:

<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.

The HTML markup generated is subject to change.
