highlight_fileSyntax highlighting of a fileDescriptionmixedhighlight_filestringfilenameboolreturn
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.
The return parameter became available in PHP
4.2.0. Before this time it behaved like the default, which is &false;
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.
Since PHP 4.2.1 this function is also affected by safe_mode and open_basedir.
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:
Creating a source highlighting URL
ForceType application/x-httpd-php
]]>
And then make a file named "source" and put it in your
web root directory.
Source DisplayERROR: Script Name needed ";
} else {
if (ereg("(\.php|\.inc)$",$script)) {
echo "
Source of: $PATH_INFO
\n\n";
highlight_file($script);
} else {
