highlight_file
(PHP 4)
Description
The highlight_file() function prints out a syntax higlighted version of the code contained in filename using the colors defined in the built-in syntax highlighter for PHP.
If the second parameter return is set to TRUE then highlight_file() will return the highlighted code as a string instead of printing it out. If the second parameter is not set to TRUE then highlight_file() will return TRUE on success, FALSE on failure.
蛁: The return parameter became available in PHP 4.2.0. Before this time it behaved like the default, which is FALSE
蛁: Care should be taken when using the show_source() and highlight_file() functions to make sure that you do not inadvertently reveal sensitive information such as passwords or any other type of information that might create a potential security risk.
蛁: Since PHP 4.2.1 this function is also affected by safe_mode and open_basedir.
瞰赽 1. Creating a source highlighting URL
To setup a URL that can code hightlight any script that you pass to it, we will make use of the "ForceType" directive in Apache to generate a nice URL pattern, and use the function highlight_file() to show a nice looking code list.
In your httpd.conf you can add the following:
Location /source ForceType application/x-httpd-php /Location
And then make a file named "source" and put it in your web root directory.
HTML HEAD TITLE Source Display /TITLE /HEAD BODY BGCOLOR="white" ?php $script = getenv ("PATH_TRANSLATED"); if(!$script) {echo "BR B ERROR: Script Name needed /B BR ";} else {if (ereg("(\.php|\.inc)$",$script)) {echo" H1 Source of: $PATH_INFO /H1 \n HR \n"; highlight_file($script);} else {echo "H1 ERROR: Only PHP or include script names are allowed /H1 ";}} echo" HR Processed: ".date("Y/M/d H:i:s",time());? /BODY /HTML
Then you can use an URL like the one below to display a colorized version of a script located in "/path/to/script.php" in your web site.
http://your.server.com/source/path/to/script.php
