HIGHLIGHT_FILE(3) 1 HIGHLIGHT_FILE(3) highlight_file - Syntax highlighting of a file SYNOPSIS
mixed highlight_file (string $filename, [bool $return = false]) DESCRIPTION
Prints out or returns a syntax highlighted version of the code contained in $filename using the colors defined in the built-in syntax highlighter for PHP. Many servers are configured to automatically highlight files with a phps extension. For example, example.phps when viewed will show the syntax highlighted source of the file. To enable this, add this line to the httpd.conf: AddType application/x-httpd-php-source .phps PARAMETERS
o $filename - Path to the PHP file to be highlighted. o $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. CHANGELOG

Caution Care should be taken when using the highlight_file(3) function to make sure that you do not inadvertently reveal sensitive informa- tion such as passwords or any other type of information that might create a potential security risk. Note When the $return parameter is used, this function uses internal output buffering so it cannot be used inside an ob_start(3) callback function. SEE ALSO
