The highlight_string() function outputs a syntax
highlighted version of str
using the colors defined
in the built-in syntax highlighter for PHP.
If the second parameter return
is set to TRUE
then highlight_string() will return the highlighted
code as a string instead of printing it out. If the second parameter is
not set to TRUE then highlight_string() will
return TRUE on success, FALSE on failure.
Note: This function internally uses the output buffering with this parameter so it can not be used inside ob_start() callback function.
Note: The
return
parameter became available in PHP 4.2.0. Before this time it behaved like the default, which is FALSE
