Replace character not working in ver 4

[oceans]

Dear people,

 

I did this

 

define

function ConvertSingleBackSlash($string)
{
return str_replace("\\", "-", $string);
}

 

later call

 

$Input[$i]=filter_var($Input[$i]=FILTER_CALLBACK,array("options"=>"ConvertSingleBackSlash"));

 

it works fine in ver 5 but not in ver 4, is there a substitue for this.

 

Thanks.

You can use a foreach() loop instead of filter_var().  I think it'll be more readable too.  There's no need to use such high level programming for such a simple task.
