PHP micro-script displays PHP, HTML, Javascript code without parsing

May 6, 2006

It's almost embarrassing to release code this miniscule, but I haven't found anything similar anywhere else on the 'Net. It displays PHP, HTML, Javascript and other source code direct from file, unparsed, and presents it cleanly and professionally. An image link brands the displayed code, and refers viewers back to the main site.

To use, call source.php with the name of the file to display, i.e.

source.php?file=source.php

Code can be saved directly, or copied and pasted, without problems.

Complete functionality derives from one simple PHP function - htmlentities():

echo '<pre 
style="background-color:#FFF3CC;padding:10px;padding-top:50px">'.
htmlentities(@file_get_contents($f)).'</pre>';

The htmlentities() function converts all PHP, HTML and other tags to non-coding, display-only character codes, without parsing. Too easy.

Full source.php code is presented here by source.php itself (in an odd sort of homage to PHP - the acronym is self-referential). More on PHP and the htmlentities() function at http://php.net/.
