Syntax highlighting of a file

说明

mixed highlight_file ( string $filename [, bool $return ] )

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

参数

filename: Path to the PHP file to be highlighted.
return: Set this parameter to TRUE to make this function return the highlighted code.

返回值

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.

更新日志

注释

Caution

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.

Note: 该函数的内部依赖这个参数使用输出缓冲，所以它不能在 ob_start() 的回调函数中使用
