preg_replace

[fizzwizz]

I want to replace a dot wth an underscore

$newstring = preg_replace("/./","_",$string);

replaces all characters in $string with an inderscore (_). How do I make this replace a dot (.) ?

thanks ... Fizz

$newstring = preg_replace("/\\./","_",$string);

You just needed a backslash.
