It's a lazy coding hack used to prevent a syntax error in the event that $cid or $hot are not defined. The 'foo' part of the string doesn't prevent the match as grep ignores it. That said, it could actually cause it to break if $dow just happens to be "foo" (or some substring of it).
A tidier solution is to instead use "$cid" or to first evaluate "$cid" and check it's defined.

classkit_method_redefine - Dynamically changes the code of the given method

SYNOPSIS
bool classkit_method_redefine (string $classname, string $methodname, string $args, string $code, [int $flags = CLASSKIT_ACC_PUBLIC]) DESCRIPTION
Note This function cannot be used to manipulate the currently running (or chained) method. Warning This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk. PARAMETERS
o $classname - The class in which to redefine the method o $methodname - The name of the method to redefine o $args - Comma-delimited list of arguments for the redefined method o $code - The new code to be evaluated when $methodname is called o $flags - The redefined method can be CLASSKIT_ACC_PUBLIC, CLASSKIT_ACC_PROTECTED or CLASSKIT_ACC_PRIVATE Note This parameter is only used as of PHP 5, because, prior to this, all methods were public. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 classkit_method_redefine(3) example <?php class Example { function foo() { return "foo! "; } } // create an Example object $e = new Example(); // output Example::foo() (before redefine) echo "Before: " . $e->foo(); // Redefine the 'foo' method classkit_method_redefine( 'Example', 'foo', '', 'return "bar! ";', CLASSKIT_ACC_PUBLIC ); // output Example::foo() (after redefine) echo "After: " . $e->foo(); ?> The above example will output: Before: foo! After: bar! SEE ALSO
