CVarDumper is intended to replace the buggy PHP function var_dump and print_r. It can correctly identify the recursively referenced objects in a complex object structure. It also has a recursive depth control to avoid indefinite recursive display of some peculiar variables.

CVarDumper can be used as follows,

CVarDumper::dump($var);

Method Details

dump() method

public static void dump(mixed $var, integer $depth=10, boolean $highlight=false)
$var	mixed	variable to be dumped
$depth	integer	maximum depth that the dumper should go into the variable. Defaults to 10.
$highlight	boolean	whether the result should be syntax-highlighted

Source Code: framework/utils/CVarDumper.php#41 (show)


public static function dump($var,$depth=10,$highlight=false)
{
    echo self::dumpAsString($var,$depth,$highlight);
}

Displays a variable. This method achieves the similar functionality as var_dump and print_r but is more robust when handling complex objects such as Yii controllers.

dumpAsString() method

public static string dumpAsString(mixed $var, integer $depth=10, boolean $highlight=false)
$var	mixed	variable to be dumped
$depth	integer	maximum depth that the dumper should go into the variable. Defaults to 10.
$highlight	boolean	whether the result should be syntax-highlighted
{return}	string	the string representation of the variable

Source Code: framework/utils/CVarDumper.php#55 (show)


public static function dumpAsString($var,$depth=10,$highlight=false)
{
    self::$_output='';
    self::$_objects=array();
    self::$_depth=$depth;
    self::dumpInternal($var,0);
    if($highlight)
    {
        $result=highlight_string("<?php\n".self::$_output,true);
        self::$_output=preg_replace('/&lt;\\?php<br \\/>/','',$result,1);
    }
    return self::$_output;
}

Dumps a variable in terms of a string. This method achieves the similar functionality as var_dump and print_r but is more robust when handling complex objects such as Yii controllers.
