highlight_file Syntax highlighting of a file &reftitle.description; mixedhighlight_file stringfilename boolreturn&false; 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;: &reftitle.parameters; filename Path to the PHP file to be highlighted. return Set this parameter to &true; to make this function return the highlighted code. &reftitle.returnvalues; 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. &reftitle.notes; Care should be taken when using the highlight_file function 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. ¬e.uses-ob; &reftitle.seealso; highlight_string Highlighting INI directives
